This thesis presents analysis of the status of IWRM implementation along with the challenges with regards to policy and institutional measures as well as the required basin information and management instruments. The research entailed a detailed analysis of water resources systems based on a case study from the Awash River Basin in Ethiopia, covering the historical and present state of the challenges and gaps in policies, institutional arrangements and management instruments. The status quo of practical water management, implications of plausible management alternatives in terms of their impact to future water availability, demand fulfilment, patterns of use, and sustainability of the environment were examined. Moreover, the interlinkages and dynamics between key water dependent resources sectors, broadly categorized into water, energy, food, and ecosystems (WEFE) was explored to identify key tradeoffs and synergies. This was deliberated as to improving the synchronization of sectoral plans and resources management programs, thereby fast-tracking the coordination process in IWRM. Overall, the research provides a clearer understanding of the system-wide problems, structural challenges and possible future consequences regarding the management and sustainability of the entire water resource system. Ultimately the purpose is to set in motion new strategies and mechanisms to improve the implementation of the currently applied IWRM framework in the context of the SDGs.

Climate change, combined with the rapid and often unplanned urbanisation trends, is associated with a rising trend in the frequency and severity of disasters triggered by natural hazards. In order to face the impacts of such threats, it is necessary to have an appropriate Disaster Risk Assessment (DRA). Traditional DRA approaches for disaster risk reduction (DRR) have focused mainly on the hazard component of risk, with little attention to the vulnerability and the exposure components. To address this issue, this dissertation's main objective is to develop and test a disaster risk modelling framework that incorporates socioeconomic vulnerability and the adaptive nature of exposure associated with human behaviour in extreme hydro-meteorological events in the context of SIDS. To achieve the objective, an Adaptive Disaster Risk Assessment (ADRA) framework is proposed. ADRA uses an index-based approach (PeVI) to assess the socioeconomic vulnerability using three components: susceptibility, lack of coping capacities, and lack of adaptation. Furthermore, ADRA explicitly incorporates the exposure component using two approaches; first, a logistic regression model was built using the actual evacuation rates observed during Hurricane Irma, and second, an Agent-based model is used to simulate how households change their exposure levels in relation to different sources of information

This open access book explores the interactions between water and earthquakes, including recent concerns about induced seismicity. It further highlights that a better understanding of the response of the water system to disturbances such as earthquakes is needed to safeguard water resources, to shield underground waste repositories, and to mitigate groundwater contamination. Although the effects of earthquakes on streams and groundwater have been reported for thousands of years, this field has only blossomed into an active area of research in the last twenty years after quantitative and continuous documentation of field data became available. This volume gathers the important advances that have been made in the field over the past decade, which to date have been scattered in the form of research articles in various scientific journals.

This book brings together contributions from experts in water management, scientists, researchers, academics and lecturers, sharing experiences and successes in this field. It is devoted to a wide range of water resources management issues, including water quality to water quantity, considering all impacts of water issues in the environment. The book presents international approaches to the latest developments in both the fundamental bases and the applicability of state-of-the-art knowledge that can be effectively used for solving a variety of large problems in integrated water resources management. The main focus of the book is on water pollution - physical, chemical, biological, and geographical pollution, hydrology problems, and limnology tasks.

The negative impacts of floods are attributed to the extent and magnitude of a flood hazard, and the vulnerability and exposure of natural and human elements. In flood risk management (FRM) studies, it is crucial to model the interaction between human and flood subsystems across multiple spatial, temporal and organizational scales. Models should address the heterogeneity that exists within the human subsystem, and incorporate institutions that shape the behaviour of individuals. Hence, the main objectives of the dissertation are to develop a modelling framework and a methodology to build holistic models for FRM, and to assess how coupled human-flood interaction models support FRM policy analysis and decision-making. To achieve the objectives, the study introduces the Coupled fLood-Agent-Institution Modelling framework (CLAIM). CLAIM integrates actors, institutions, the urban environment, hydrologic and hydrodynamic processes and external factors, which affect FRM activities. The framework draws on the complex system perspective and conceptualizes the interaction of floods, humans and their environment as drivers of flood hazard, vulnerability and exposure. The human and flood subsystems are modelled using agent-based models and hydrodynamic models, respectively. The two models are dynamically coupled to understand human-flood interactions and to investigate the effect of institutions on FRM policy analysis.

These approaches are chosen to address a wide range of hydrologic system characteristics, processes, and the associated problems. Each of these eight approaches includes a comprehensive review of the fundamental concepts, their applications in hydrology, and a discussion on potential future directions.

This book presents solutions to address water security in rapidly urbanizing cities, and explores the new paradigms of water security in changing contexts. Highlighting the latest developments in water research, changes in water policy, and current discourses on water security, the book also provides information and tools for local stakeholders, water managers, and policymakers to build the capacity for sustainable water governance. The book discusses a wide range of sustainable solutions and their implementation to ensure that the balance between water supply and demand remains sustainable in the long term, with a focus on local solutions to build capacity and developing policy awareness for a wide range of stakeholders. As the concept of urban water security in changing contexts is open to multiple interpretations, the authors set out various approaches. Providing an overview of the changing perspectives of urban water security in different contexts, the book is based on findings of the Asia-Pacific Network water security project at the United Nations University, Tokyo, as well as the authors' current research-based at Pokhara University, Nepal, Hosei University, Tokyo, Institute for the Global Environmental Strategies, Japan and the Australian National University, Australia. The book also includes the views of international authorities (such as water experts) on the subject. The solutions are complemented by analysis of case studies of various localized sustainable solutions at different scales. The book is a valuable resource for water professionals and policymakers around the globe, academics, teachers working in water-related areas, NGOs, think thanks, water research institutes, donor organizations, and international and local water utility services.

The completion of the initial phase of the U.S. National Acid Precipitation Assessment Program (NAPAP) in 1990 marked the end of the largest environmental research and assessment effort to that time. The resulting series of 27 State of Science and Technology (SOS/T) Reports and the NAPAP Integrated Assessment represent a decade of work by hundreds of scientists, engineers, and economists. Since then, many new, significant, more refined studies on acid deposition have been completed and published, considerably broadening knowledge in this area. Aquatic Effects of Acidic Deposition summarizes and synthesizes these major advancements, particularly those topics that are directly relevant to policy making. It offers complete coverage of recent findings that have substantiated, deepened, modified, or in some cases, revolutionized scientific understanding in environmental research. This resource addresses the quantification of effects and recent developments in predictive modelling capabilities. It covers virtually all aspects of nitrogen effects research, the importance of natural sources of acidity, the influence of land use and landscape change on drainage water chemistry, and the role of short-term episodic events. This comprehensive update thoroughly illustrates the progression and refinement in the field. Aquatic Effects of Acidic Deposition helps you make educated decisions based on the most recent, reliable data for air pollution sensitivities, effects, remediation, and future research.

Urban climate adaptation currently focusses mainly on hazards but often ignores opportunities which arise in both space and time. Opportunistic Adaptation provides a rationalized approach to mainstream measures for climate adaptation into urban renewal cycles. Adaptation opportunities are identified by projecting the lifespans of urban assets into the future to obtain an operational urban adaptation agenda for the future. Upscaling of the adaptation process is done by synchronizing the end-of-lifecycle of a group of assets to develop adaptation clusters that comprise multiple dwellings, infrastructure as well as public spaces. An extensive catalogue of adaptation measures for different scale-levels ensures flexibility in the type of measures that can be integrated. Sequencing the adaptation measures over long periods of time provides insight and flexibility in the long-term protection standards that can be achieved. By applying a design-centered approach, the potentials of obtaining co-benefits in the urban landscape are maximized. Potentials of clustering of nature-based solutions are being considered which ensures to maximize the delivery of ecosystem services. This research aims to assess \the adaptation potential of Bangkok, based on a case study area (Lat Krabang) by mapping the adaptation opportunities and flood vulnerability. The resulting outputs will contribute to the development of a flexible and inclusive FRM strategy.

Water utilities worldwide lose 128 billion cubic meters annually, causing annual monetary losses estimated at USD 40 billion. Most of these losses occur in developing countries (74%). This calls for rethinking the challenges facing water utilities in developing countries, foremost of which is the assessment of water losses in intermittent supply networks. Water loss assessment methods were originally developed in continuous supply systems, and their application in intermittently operated networks (in developing countries) is hindered by the widespread use of household water tanks and unauthorised consumption. This study provides an extensive review of existing methods and (software) tools for water loss assessment. In addition, several new methods were developed, which offer improved water loss assessment in intermittent supply. As the volume of water loss varies monthly and annually according to the amount of supplied water, this study proposes procedures to normalise the volume of water loss in order to enable water utilities to monitor and benchmark their performance on water loss management. The study also developed a novel method of estimating apparent losses using routine data of WWTP inflows, enabling future real-time monitoring of losses in networks. Different methods have also been suggested to estimate the unauthorised consumption in networks. This study found that minimum night flow analysis can still be applied in intermittent supply if an area of the network is supplied for several days. Furthermore, this study concluded that water meter performance is enhanced in intermittent supply conditions. However, continuous supply in the presence of float-valves significantly reduces the accuracy of water meters. Finally, this study provides guidance and highlights several knowledge gaps in order to improve the accuracy of water loss assessment in intermittent supply. Accurate assessment of water loss is a prerequisite for reliable leakage modelling and minimisation as well as planning for, and monitoring of water loss management in distribution networks.

Water is not only a source of life and culture. It is also a source of power, conflicting interests and identity battles. Rights to materially access, culturally organize and politically control water resources are poorly understood by mainstream scientific approaches and hardly addressed by current normative frameworks. These issues become even more challenging when law and policy-makers and dominant power groups try to grasp, contain and handle them in multicultural societies. The struggles over the uses, meanings and appropriation of water are especially well-illustrated in Andean communities and local water systems of Peru, Chile, Ecuador, and Bolivia, as well as in Native American communities in south-western USA.

The problem is that throughout history, these nation-states have attempted to 'civilize' and bring into the mainstream the different cultures and peoples within their borders instead of understanding 'context' and harnessing the strengths and potentials of diversity. This book examines the multi-scale struggles for cultural justice and socio-economic re-distribution that arise as Latin American communities and user federations seek access to water resources and decision-making power regarding their control and management. It is set in the dynamic context of unequal, globalizing power relations, politics of scale and identity, environmental encroachment and the increasing presence of extractive industries that are creating additional pressures on local livelihoods.

While much of the focus of the book is on the Andean Region, a number of comparative chapters are also included. These address issues such as water rights and defence strategies in neighbouring countries and those of Native American people in the southern USA, as well as state reform and multi-culturalism across Latin and Native America and the use of international standards in struggles for indigenous water rights. This book shows that, against all odds, people are actively contesting neoliberal globalization and water power plays. In doing so, they construct new, hybrid water rights systems, livelihoods, cultures and hydro-political networks, and dynamically challenge the mainstream powers and politics.

Visual Spatial Enquiry explores visual and textual ways of working within spatial research. Architects and spatial thinkers from the arts, social sciences and humanities present rich case studies from remote and regional settings in Australia to the suburbs of Los Angeles, and from gallery and university settings to community collaborations in Mongolia. Through these case studies the authors reappraise and reconsider research approaches, methods and processes within and across their fields. In spatial research diagramming can be used as a method to synthesise complex concepts into a succinct picture, whereas metaphors can add the richness of lived experiences. Drawing on the editors' own architectural backgrounds, this volume is organised into three key themes: seeing, doing and making space. In seeing space chapters consider observational research enquiries where developing empathy for the context and topic is as important as gathering concrete data. Doing space explores generative opportunities that inform new and innovative propositions, and making space looks at ways to rethink and reshape spatial and relational settings. Through this volume Creagh and McGann invite readers to find their own understandings of the value and practices of neighbouring fields including planning, geography, ethnography, architecture and art. This exploration will be of value to researchers looking to develop their cross-disciplinary literacy, and to design practitioners looking to enhance and articulate their research skills.

This book contains the written, thoroughly reviewed versions of both invited lectures and regular presentations given at the 36th International School of Hydraulics, held at Jachranka in Poland on May 23-26, 2017. The contributions cover recent findings in the areas of mathematical modeling as well as experimental investigations related to free surface flows and pollution, sediment and heat transport processes in rivers. Better understanding of environmental flows requires cognition of physical, chemical and biological attributes of flowing water and therefore hydraulic research becomes strongly interdisciplinary field of science. The authors also realize that fundamental knowledge of environmental hydraulics problems is absolutely essential for planning and design of systems to manage water resources. Nowadays the readers face a rapid development of hydraulic research due to a boom in the computer sciences and measurement techniques and this is what this book is about. Eminent world leading experts in this field and young researchers from sixteen countries from all over the world contributed to this book.

Providing an introduction to the crucially important topic of groundwater, this text covers all major fields of hydrogeology and includes outlines of the occurrence of groundwater in various rock types, the movement and storage of groundwater, the formulation of groundwater balances, the development of groundwater chemistry, as well as the practical application of hydrogeology for groundwater development. Following a unique systems approach to describe and connect its various elements, the text also explores a large selection of examples of groundwater cases from various parts of the world. In addition, theoretical sections and examples are illustrated with a number of drawings, photos and computer printouts. Suitable for education in hydrogeology at postgraduate and graduate level, the text is also a useful reference tool for professionals and decision-makers involved in water or water-related activities. In the revised paperback edition of Introduction to Hydrogeology (February 2006), suggestions of reviewers, students and colleagues have been taken into account. This means that more attention is paid to the processes in the unsaturated zone, especially those relating to groundwater recharge. Also, in the revised edition, the investigation methods are highlighted in the sections where the related theory is dealt with, and they are not presented in the last chapter on groundwater management. Chapter titles are re-named and some definitions are adjusted. The References and Bibliography section is also extended, some figures are improved, and the inevitable 'typing errors' are corrected as well. (c) 2009, Second edition, with revisions 2012.

This research aims to investigate the prevailing sediment dynamics and the sediment budget in the Mekong Delta by using a process-based model. Understanding sediment dynamics for the Mekong Delta requires high resolution analysis and detailed data, which is a challenge for managers and scientists. This study introduces such an approach and focuses on modeling the entire system with a process-based approach with Delft3D-4 and Delft3D Flexible Mesh (DFM). The first model is used to explore sediment dynamics at the coastal zone. The latter model allows straightforward coupling of 1D and 2D grids, making it suitable for analyzing the complex river and canal network of the Mekong Delta. The validated model suggests that the Mekong Delta receives ~99 Mt/year sediment from the Mekong River. This is much lower than the common estimate of 160 Mt/year. Only about 23% of the modelled total sediment load at Kratie is exported to the sea. The remaining portion is trapped in the rivers and floodplains of the Mekong Delta. The results advance understanding of sediment dynamics and sediment budget in the Mekong Delta. As such the model is an efficient tool to support delta management and planning.
