The aim of this book is to contribute to understanding risk knowledge and to forecasting components of early flood warning, particularly in the environment of tropical high mountains in developing cities. This research covers a challenge, taking into account the persistent lack of data, limited resources and often complex climatic, hydrologic and hydraulic conditions. In this research, a regional method is proposed for assessing flash flood susceptibility and for identifying debris flow predisposition at the watershed scale. An indication of hazard is obtained from the flash flood susceptibility analysis and continually, the vulnerability and an indication of flood risk at watershed scale was obtained. Based on risk analyses, the research follows the modelling steps for flood forecasting development. Input precipitation is addressed in the environment of complex topography commonly found in mountainous tropical areas. A distributed model, a semi-distributed model and a lumped model were all used to simulate the discharges of a tropical high mountain basin with a paramo upper basin. Performance analysis and diagnostics were carried out in order to identify the most appropriate model for the study area for flood early warning. Finally, the Weather Research and Forecasting (WRF) model was used to explore the added value of numerical weather models for flood early warning in a paramo area.

Mountains are water towers of our world, but their role in global water resources may be altered due to changing climate. This book provides an integrated assessment of the spatial and temporal variability of both recent and future climate change impacts in the Yellow River source region (YRSR) with specific focus on extremes. The book is structured across four different topics from detecting contemporary hydro-climatic changes, comparing three different statistical downscaling methods, assessing elevation dependency of expected changes in temperature, and projecting future climate-induced hydrologic changes in the YRSR. The detection of historical hydro-climatic changes in recent decades indicates that climate change may already be happening and may pose a serious threat to water availability in this region. However, an ensemble of climate change projections for the periods 2046-2065 and 2081-2100 based on two GCMs and three emission scenarios demonstrates that the future water availability of this region would increase due to climate change. This discrepancy suggests that contemporary hydro-climatic experience based on past records alone may not always provide a reliable guide to the future. This study makes an important contribution toward an improved understanding of climate change impacts in the YRSR. The knowledge generated has major implications for water resources management in the Yellow River and will be instructive for climate change impacts studies in other mountain areas.

Since the 1980s a major change took place in public policies for water resources management. The role of governments shifted under this reform process from an emphasis on investment in the development, operation and maintenance of water infrastructure to a focus on managing water resources systems by stipulating general frameworks and defining key principles for water allocation. This interdisciplinary research examines how this water reform process unfolds within four African waterscapes that are historically constituted by natural and social processes. The study analyzes the interplay between public policies designed and implemented by government agencies and the institutions that govern access to and control over water resources among groups of agricultural water users. The findings of this research show that the water reform policies have led to similar outcomes in dissimilar contexts and that water policy only to a limited extent leads to progressive institutional change concerning agricultural water use, especially in this neoliberal era. Moreover, this research shows that excluding targeted investments in the development of hydraulic infrastructure for historically disadvantaged groups has narrowed the options of the governments to redress the colonial legacy and the capacity of small-scale farmers to move their livelihood beyond subsistence.

Once a prosperous region, the Ganga-Brahmaputra-Meghna (GBM) river basin-inhabited by about a tenth of the world's population-is currently one of the poorest. Large-scale socioeconomic development is urgently needed to ensure the sustainability of the region, and the management of water resources is a crucial part of this. Ganga-Brahmaputra-Meghna Waters: Advances in Development and Management discusses water resource development and management issues related to the GBM river basin, including interactions, institutional set ups, and future perspectives. It also proposes several novel technologies, developed by the author, to help revolutionize the development of India's waters. Written by an authority in water resource management studies, the book addresses the need for a holistic, integrated, basin-wide approach to improve the quality of life for people living within the region. Pointing out that water does not recognize political boundaries, the text also discusses Nepal, Bangladesh, and Bhutan as integral parts of the GBM basin. The author suggests that the unique geophysical and hydrologic characteristics of the basin present an opportunity for technologies that can increase the available water and hydroelectric potential in the region. The proposed advances can also help generate collaborative development between India and its neighboring countries. The book emphasizes the adoption of a societal-environmental systems management approach, which treats the physical and social-environmental systems as integral components, backed by participatory transparent modeling. It also argues that technology must be considered a key part of the system. A unique contribution to water resources engineering, this book provides readers with a case study of the development and management of the world's largest water system. It offers new perspectives and useful advice for other countries and regions developing river and irrigation plans and for policy makers involved in large-scale water resources engineering.

For integrated water resources management both blue and green water resources in a river basin and their spatial and temporal distribution have to be considered. This is because green and blue water uses are interdependent. In sub-Saharan Africa, the upper landscapes are often dominated by rainfed and supplementary irrigated agriculture that rely on green water resources. Downstream, most blue water uses are confined to the river channels, mainly for hydropower and the environment. Over time and due to population growth and increased demands for food and energy, water use of both green and blue water has increased. This book provides a quantitative assessment of green-blue water use and their interactions. The book makes a novel contribution by developing a hydrological model that can quantify not only green but also blue water use by many smallholder farmers scattered throughout the landscape. The book provides an innovative framework for mapping ecological productivity where gross returns from water consumed in agricultural and natural vegetation are quantified. The book provides a multi-objective optimization analysis involving green and blue water users, including the environment. The book also assesses the uncertainty levels of using remote sensing data in water resource management at river basin scale.

The enhanced biological removal of phosphorus (EBPR) is a popular process due to high removal efficiency, low operational costs, and the possibility of phosphorus recovery. Nevertheless, the stability of the EBPR depends on different factors such as: temperature, pH, and the presence of toxic compounds. While extensive studies have researched the effects of temperature and pH on EBPR systems, little is known about the effects of different toxic compounds on EBPR. For example, sulphide has shown to inhibit different microbial activities in the WWTP, but the knowledge about its effects on EBPR is limited. Whereas the sulphide generated in the sewage can cause a shock effect on EBPR, the continuously exposure to sulphide potentially generated in WWTP can cause the acclimatization and adaptation of the biomass. This research suggests that sulphate reducing bacteria can proliferate in WWTP, as they are reversibly inhibited by the recirculation of sludge through anaerobic-anoxic-oxic conditions. The research enhances the understanding of the effect of sulphide on the anaerobic-oxic metabolism of PAO. It suggests that the filamentous bacteria Thiothrix caldifontis could play an important role in the biological removal of phosphorus. It questions the ability of PAO to generate energy from nitrate respiration and its use for the anoxic phosphorus uptake. Thus, the results obtained in this research can be used to understand the stability of the EBPR process under anaerobic-anoxic-oxic conditions, especially when exposed to the presence of sulphide.

Quantitative research with respect to the combination of engineering and socialcultural- religious aspects based on the Tri Hita Karana philosophy in Subak irrigation schemes is original in the field of land and water development. A scenario analysis needs a good and careful system approach. Based on a Generic Algorithm the RIBASIM model was applied using the dependable 80% of discharge and shifting the start of land preparation. The results provide evidence that the cropping pattern of the fifth scenario results in an overall optimal agriculture production of the Subak schemes. The recoverable flow considered in the river basin scheme model plays an important role in the optimisation. Nevertheless, if a normal hydro-climate occurs, the other scenarios, especially the first scenario, can be applied as well. When the indigenous knowledge of farmers is compromised with present day knowledge of agricultural and technological developments, capability of these farmers increases, thus reflects the applicability of the Tri Hita Karana philosophy on harmony among people and harmony among people and nature.

The book presents documentary evidence of the insufficiency of rehabilitation works to close the gap between the irrigation service and actual area irrigated of publicly funded national irrigation systems in the Philippines. It outlines a methodology for formulating a modernisation plan for national irrigation systems with focus on the mostly ungauged, medium to small canal irrigation systems. The proposed methodology adaptively modified some known modernisation concepts and techniques and integrated them in a more holistic framework in the context of changing weather patterns and river flow regimes. It includes in-depth review of rehabilitation works; system diagnosis; revalidation of design assumptions on percolation and water supply; characterisation of system management, irrigation service and demand; and drawing up of options and a vision for the modernised irrigation systems. Central to the proposed modernisation strategy is the logical coherence among the design of physical structures, system operation and water supply so that improvements of irrigation service are possible. The book discusses the development of the proposed methodology and demonstrates its utility in two case study irrigation systems.

International cooperation for reaching development goals has expanded gradually since the 1950s. The effectiveness of the Overseas Development Aid (ODA) has become a topic of great public interest. A growing body of experience exists to demonstrate that finance alone is not sufficient for development, and capacity and knowledge are increasingly seen as the constraints to proper decision making, absorption of funds, and effective results on the ground. This book presents the investigation into the role of Knowledge and Capacity Development (KCD) in public water resources management in Indonesia and the Netherlands. The two cases indicate that the institutional environment is defining for the type of knowledge and capacity development that is prevailing in that period and it also determines the formal organisational structure and the KCD mechanisms in use. The cases further show the importance yet the low valuation of tacit knowledge, while the Indonesian case also suggests that tacit knowledge is among the most important assets gained from international post-graduate education. The conceptual model introduced in this book allows to measure knowledge and capacity at three nested levels: the institutional, organisational and individual level. It provides insight in the numerous contextual factors that influence knowledge and capacity and KCD mechanisms.

After World War II, international development became the world leading development model, but its effectiveness is much debated. Nowadays, it is acknowledged that international development can effectively support development through knowledge and capacity development (KCD). Nonetheless, understanding what capacity really consists of in operational terms and what its development entails remains a challenge. This book investigates KCD processes in water utilities in Sub-Saharan Africa. The three cases analysed reveal that the learning impact of KCD on utilities depends on whether they are able to close their learning cycle, i.e., to ensure that improved capacity is also translated into mainstream behaviour. This finding challenges conventional wisdom for which KCD translates "automatically" into improved performance. Hence the need to focus KCD evaluation on both capacity improvement and capacity application. The proposed learning-based framework for KCD identifies two distinct but interrelated stages in KCD, namely knowledge transfer and knowledge absorption. Knowledge absorption usually takes time due to slow organisational processes that govern it. However, in practice it is often taken for granted. The framework also identifies the key factors that shape learning processes in water utilities. The book argues that water utilities in Sub-Saharan Africa can reinvent themselves by embracing change management approaches and striving to become learning organisations.

First Published in 2002. Oil is of strategic significance. The bulk of the earth's known oil reserves, more than 70 percent, is concentrated in the Persian Gulf area. And although alternative energy sources have been vigorously pursued, the United States continues, since 1970, to import from the Persian Gulf 24 percent of needed oil for her own consumption. Since this study was completed thirty years ago there have been several major events related to the control of the flow of Gulf oil. This work narrates the history of the world's power struggle over the control of oil in the Persian Gulf from the time of the signing of the earliest oil concessions in 1901 until 1971.

Anaerobic oxidation of methane (AOM) coupled to sulfate reduction (AOM-SR) is a biological process mediated by anaerobic methanotrophs (ANME) and sulfate reducing bacteria. It has scientifi c and societal relevance in regulating the global carbon cycle and biotechnological application for treating sulfate-rich wastewater. This research aimed to enhance the recent knowledge on ANME distribution and its enrichment in different bioreactor confi gurations, i.e. membrane bioreactor (MBR), biotrickling fi lter (BTF) and high pressure bioreactor (HPB). Marine sediment from Ginsburg mud volcano, Gulf of Cadiz was used as inoculum in the BTF and MBR. The BTF operation showed the enrichment of ANME in the biofi lm, especially ANME-1 (40%) and ANME-2 (10%). Whereas, the dominancy of ANME-2 and Desulfosarcina aggregates was observed in the MBR. Moreover, HPB study was performed by using highly enriched ANME-2 community from Captain Arutyunov mud volcano. During the study of HPB at different temperature and pressure conditions, the incubation at 10 MPa pressure and 15 C was observed to be the most suitable condition for the studied AOM-SR community. Furthermore, AOM-SR activity in the coastal sediments from marine Lake Grevelingen (the Netherlands) was explored and the microbial community was characterised which was dominated by ANME-3 among known ANME types.

Considers the role of economics in discussions about the depletion of finite stocks of natural resources including oil.

Taking the case of the Norwegian petroleum industry as its vantage point, the book discusses the question of industrial transformations in resource-based industries. The book presents new, empirically-based analyses of the development of the petroleum industry, with an emphasis on three ongoing transformation processes: Technological upgrading and innovation in upstream petroleum. Globalisation of the petroleum industry and suppliers' experiences of entering foreign markets. Diversification into and out of petroleum - and the potential for new growth paths after oil. Drawing together a range of key thinkers in this field, this volume addresses the ways in which the petroleum industry and its supply industry has changed since the turn of the millennium. It provides recommendations for the development of resource economies in general and petroleum economies in particular. This book will be of great interest to students and scholars of energy policy and economics, natural resource management, innovation studies and the politics of the oil and gas sector.

The discussion on arsenic in the environment is complex and must grasp the importance of very many, mostly unrelated works on individual aspects. This volume represents one of the first comprehensive and interdisciplinary examinations into arsenic's behaviour in air, water, soils, sediments, plants and the human body. Based on state-of-the-art investigations into the global arsenic cycle, the related human toxicology and available remediation technologies, arsenic is assessed holistically in all the environmental compartments. Using the results of primary research, the authors offer concrete suggestions for risk reduction and management of environmental pollution that allow the reader to successfully tackle similar problems and find sustainable solutions. The book consists of three essential parts: Review of the current knowledge of arsenic behaviour in the environment (global biogeochemical cycles), toxicology, remediation techniques, immobilization technologies and environmental legislation Case studies for mining-related arsenic problems Discussion of mitigation and remediation technologies and approaches such as environmental education, hygiene training, backed by real experience and successful implementation in the study area In a highly coherent manner, the book makes use of 120 tables and figures, a large number of literature citations, and very detailed subject index (that encompasses references) to provide rapid and up-to-date access to all relevant information. Cross-references provide a great manoeuvrability between the chapters. The book delivers very insightful and hands-on approaches for graduate students and professionals working on arsenic questions not only in environmental science, but also in the fields of environmental engineering, medicine and social science.

'A remarkably hopeful and useful book...The climate crisis leaves us no choice but to build a new world and as Sanderson makes clear, we are capable of making it a better one than the dirty and dangerous planet we've come to take for granted.' Bill McKibben, Observer book of the week We depend on a handful of metals and rare earths to power our phones and computers. Increasingly, we rely on them to power our cars and our homes. Whoever controls these finite commodities will become rich beyond imagining. Sanderson journeys to meet the characters, companies, and nations scrambling for the new resources, linking remote mines in the Congo and Chile's Atacama Desert to giant Chinese battery factories, shadowy commodity traders, secretive billionaires, a new generation of scientists attempting to solve the dilemma of a 'greener' world.

Any sustainable groundwater development programme requires knowledge of the prevailing flow system, extending from local to regional scale. This book of selected papers discusses integral groundwater management with scale flow issues and presents methods of defining, preventing, controlling and mitigating negative environmental impacts related to groundwater. It highlights specific issues such as trans-boundary groundwater flow, groundwater recharge, groundwater mining, and groundwater flow in thick aquifers, and stresses the importance of the sustainable development of groundwater and its social and economic implications. The book will interest groundwater researchers and professionals, students, government administrators and educators, providing new insights into the procedures and processes that are influenced by the scale of the groundwater flow system.

Sediment pollution and accumulation in harbours are major environmental issues and studies that advance their solutions are essential for harbour sustainability. This book provides the first comprehensive assessment of chemical pollution in sediments and sediment accumulation rates in the tropical Tema Harbour (Ghana). This book contributes to improving our ability to use an integrated approach involving sediment chemistry and bioassays in one comprehensive assessment of the contamination state of a tropical coastal environment. Whole-sediment toxicity bioassays using the amphipod Corophium volutator and the polychaete Hediste diversicolor as bioindicators were combined with data on concentrations of total metal and metal binding forms, radionuclides, organochlorine pesticides and polycyclic aromatic hydrocarbons in bottom sediments as well as total metal concentrations in settling silt-clay particles collected by sediment traps to characterise the hazard, risk and impact of sediments from the tropical coastal Tema Harbour.

Pollution of waterbodies and the environment by petroleum industry is of particular concern in Nigeria. This problem can be addressed by the application of constructed wetlands (CWs) which is a nature-based system that is simple to construct, have low operational and maintenance costs in terms of supply of energy and its periodic maintenance. The application of CWs in Nigeria for polishing of petroleum refinery wastewater is an unprecedented research. This PhD thesis focused on some specific objectives which were characterization of treated secondary refinery wastewater, design, construction, operation and monitoring of planted (T. latifolia, C. alternifolius and C. dactylon) and unplanted vertical subsurface flow, horizontal subsurface flow and hybrid CWs for the removal of suspended solids, nutrients, heavy metals, organic matter and organic pollutants. The CWs effectively treated the petroleum contaminated wastewater to effluent compliance limits. In this study, T. latifolia planted CWs had consistently higher removal efficiencies for all the measured parameters than C. alternifolius and C. dactylon planted CW systems. Therefore, in order to improve the wastewater quality discharged by Kaduna Refining and Petrochemical Company (KRPC) Nigeria, meet stringent guidelines and protect the recipient streams, installation of CWs at the effluent discharge point of KRPC is strongly recommended.

This research investigated new approaches to control anaerobic methane oxidation coupled to sulfate reduction (AOM-SR) and enrich anaerobic methanotrophs (ANME) and sulfate reducing bacteria (SRB) with the purpose of designing a suitable bioreactor for AOM-SR at ambient pressure and temperature. The current knowledge about AOM and the microorganisms involved in AOM are discussed. The effect of different substrates and pressures was investigated on the ANME and SRB community adapted to the shallow marine Lake Grevelingen, the Netherlands. Further, microorganisms from the Alpha Mound (Spain) deep sediment were enriched with methane gas as substrate in biotrickling filters (BTF) at ambient conditions for 147-230 days of operation. The effect of alternative sulfur compounds (sulfate, thiosulfate and elemental sulfur) were studied and the microbial community was characterized. The highest AOM and sulfate reduction rates were obtained in the BTF fed with thiosulfate as the electron acceptor (~0.4 mmol l-1 day-1), but the highest number of ANME was visualized in the sulfate fed BTF (ANME-2 43% of the total visualized archaea). A BTF was proposed as a suitable bioreactor for the enrichment of ANME and SRB at ambient pressure and temperature which could be potentially used for future biotechnological applications.

This volume in the Fundamentals for the Water and Wastewater Main Operator series covers the basics of piping and valves in water and wastewater plants, including details on fittings, strainers, filters, traps and control systems. The book explains how pipes and valves are used to feed materials (e.g., chemicals) into influents and effluents and siphon off unwanted liquid and gaseous by-product. Also covered is how pipes are developed into systems and subsystems and coordinated into a plant-wide functioning unit.

This volume provides readers with an opportunity to learn from front line water managers of watershed-based agencies across Canada about integrated water management (or integrated water resource management). In common with practice in much of the world, the responsibility for implementing integrated watershed management in Canada is fragmented. Each province and territory in Canada has developed unique approaches or governance models to guide decision making in that regard. Thus, this edited volume enables readers from around the world to gain insight on the best practices in Canada for achieving success and addressing barriers to implement IWM. Although there remains non consensus about how to "best" approach river basin management, some of the main observations include: There is a need to balance a focus on "the big picture", with scoping the scale and scope of planning activities in order that feasible and effective solutions can be implemented Three types of integration are popular among the agencies included in the book: (i) among environment, economy and society, (ii) interactions between people and the environment and (iii) integration (or coordination) of administrative activities. Much more attention is required to achieving effective engagement from Indigenous communities The chapters were originally published in a special issue of the International Journal of Water Resources Development.

The Fukushima disaster continues to appear in national newspapers when there is another leakage of radiation-contaminated water, evacuation designations are changed, or major compensation issues arise and so remains far from over. However, after five years, attention and research towards the disaster seems to have waned despite the extent and significance of the disaster that remains. The aftermath of Fukushima exposed a number of shortcomings in nuclear energy policy and disaster preparedness. This book gives an account of the municipal responses, citizen's responses, and coping attempts, before, during, and after the Fukushima crisis. It focuses on the background of the Fukushima disaster, from the Tohoku earthquake to diffusion on radioactive material and risk miscommunication. It explores the processes and politics of radiation contamination, and the conditions and challenges that the disaster evacuees have faced, reflecting on the evacuation process, evacuation zoning, and hope in a post-Fukushima environment. The book will be of great interest to students and scholars of disaster management studies and nuclear policy.
