The Marcell Experimental Forest (MEF) in Minnesota serves as a living laboratory and provides scientists with a fundamental understanding of peatland hydrology, acid rain impacts, nutrient and carbon cycling, trace gas emissions, and controls on mercury transport in boreal watersheds. Its important role in scientific research continues to grow as the data gathered offers invaluable insight into environmental changes over the last century and goes far in answering many of today's pressing questions at landscape and global scales. Synthesizing five decades of research, Peatland Biogeochemistry and Watershed Hydrology at the Marcell Experimental Forest includes hundreds of research publications, dozens of graduate theses, and even some previously unpublished studies. Research at the MEF has been at the forefront of many scientific disciplines and these 15 chapters offer the depth and breadth of long-term studies on hydrology, biogeochemistry, ecology, and forest management on peatland watersheds at the MEF. Focusing on peatlands, lakes, and upland landscapes, the book begins with the pioneering research on hydrology done during the 1960s. It presents the innovative 1970's studies of atmospheric deposition; the 1980's research into nutrient cycles including carbon, nitrogen, and methane emissions; and the 1990's investigations into mercury deposition. The book concludes with a look at the latest and on-going studies such as this century's research into controls on methylmercury production and landscape-level carbon storage and cycling. Covering 50 years of research and written by a veritable who's who in peatland and forestry science, this important milestone in the collection of ecological data highlights bright prospects for future research, including the continuation of existing long-term measurements, the initiation of new monitoring programs, and plans for unprecedented studies on climate change.

Tremendous improvements in ground-water sampling methodologies and analytical technologies have made it possible to collect and analyze truly representative samples to detect increasingly lower levels of contaminants now in the sub-parts-per-billion range. Though these new methods produce more accurate and precise data and are less expensive, many companies and government agencies are reluctant to update their sampling protocols and regulations claiming the transition would be too costly. The Essential Handbook of Ground-Water Sampling clearly details the economic and scientific case for adopting these new methodologies. Citing examples of unnecessary expenditure due to the inaccuracy of out-dated techniques, the editors point out that the expense of making incorrect decisions based on poor quality samples clearly negates any savings that might be realized by using older, more inefficient, and effectively short-sighted, methods. Using numerous figures, tables, and references to recent research, the editors explain the efficiency of utilizing newer, more accurate, techniques that produce higher quality data. The text provides a detailed discussion of every aspect of ground-water sampling from the development of a sampling and analysis plan, through sample collection, pretreatment, handling, shipping, and analysis, to the documentation, interpretation, and presentation of ground-water quality data. Successful sampling events and accurate data provide a sound foundation for making important, potentially expensive decisions regarding site monitoring, risk assessment, remediation, and closure. Armed with the information presented in this handbook, environmental professionals will be able to make sound technological and economic decisions regarding the choice of sampling equipment, methodologies, and procedures to meet their site-specific objectives and ensure the success of their ground-water sampling programs.

R5,778 Discovery Miles 57 780 Ships in 10 - 15 working days

This study investigates the patterns that describe reliability of water distribution networks focusing to the node connectivity, energy balance, and economics of construction, operation and maintenance. A number of measures to evaluate the network resilience has been developed and assessed to arrive at more accurate diagnostics of regular and irregular demand scenarios. These measures have been proposed as a part of the methodology for snap-shot assessment of network reliability based on its configuration and hydraulic performance. Practical outcome of the research is the decision support tool for reliability-based design of water distribution networks. This computer package named NEDRA (Network Design and Reliability Assessment) consists of the modules for network generation, filtering, initialisation, optimisation, diagnostics and cost calculation, which can be used for sensitivity analyses of single network layout or assessments of multiple layouts. The study concludes that none of the analysed aspects develops clear singular patterns. Nevertheless, the proposed network buffer index (NBI) and the hydraulic reliability diagram (HRD) as visual representation of the network resilience give sufficient snap-shot pointing the composition of the index value, and displaying possible weak points in the network that can be hidden behind the averaged values of various reliability measures.

Growing scarcity of freshwater worldwide brings to light the need for sound water resource modeling and policy analysis. While a solid foundation has been established for many specific water management problems, combining those methods and principles in a unified framework remains an ongoing challenge. This Handbook aims to expand the scope of efficient water use to include allocation of sources and quantities across uses and time, as well as integrating demand-management with supply-side substitutes. Socially efficient water use does not generally coincide with private decisions in the real world, however. Examples of mechanisms designed to incentivize efficient behavior are drawn from agricultural water use, municipal water regulation, and externalities linked to water resources. Water management is further complicated when information is costly and/or imperfect. Standard optimization frameworks are extended to allow for coordination costs, games and cooperation, and risk allocation. When operating efficiently, water markets are often viewed as a desirable means of allocation because a market price incentivizes users to move resources from low to high value activities. However, early attempts at water trading have run into many obstacles. Case studies from the United States, Australia, Europe, and Canada highlight the successes and remaining challenges of establishing efficient water markets.

R2,101 Discovery Miles 21 010 Ships in 10 - 15 working days

Water resources in tourist islands have been severely threatened, especially in the Galapagos Islands, where the increased local population has generated attractive income from the tourist services. In addition, the data regarding water supply and demand are scarce. This study investigates water supply and demand in Santa Cruz, the most populated island of Galapagos. The research encompasses a thorough assessment of the water supply crisis, as well as the quantification of water demand from different categories (domestic, tourist, restaurants and laundries) through surveys, in the absence of water metering. Also, specific water demand was assessed by installing 18 water meters. The results yield a wide range of water consumption, questioning the current assumption of water scarcity. Furthermore, a prognosis of water supply and demand was carried out, and also several intervention strategies were proposed such as rainwater harvesting, greywater recycling, leakage reduction, water meter installation, water demand reduction, as well as seawater desalination to cope with the future population growth. Due to the fragility of the ecosystem, these strategies were assessed through a Multi-Criteria Decision Analysis, considering environmental, technical, economic and social aspects, as well as relevant stakeholders' perspectives. finally, the water supply network of Puerto Ayora was evaluated in order to understand the need of the current intermittent supply regime. A methodology was developed to estimate the overflow of the domestic roof tanks (a common incidence amongst local population). The results question the practicality of individual household storage. The final results show that the current situation in terms of the lack of water quantity may not be real, as it has been thought for the last decades. The water issues refer more importantly to the water quality, as well as to the lack of proper water management practices.

R1,573 Discovery Miles 15 730 Ships in 10 - 15 working days

At the UN General Assembly in 1997, an overwhelming majority of States voted for the adoption of the United Nations Convention on the Law of the Non-Navigational Uses of International Watercourses - a global overarching framework governing the rights and duties of States sharing freshwater systems. Globally, there are 263 internationally shared watersheds, which drain the territories of 145 countries and represent more than forty percent of the Earth's land surface. Hence, inter-State cooperation towards the sustainable management of transboundary water supplies, in accordance with applicable international legal instruments, is a topic of crucial importance, especially in the context of the current global water crisis. This volume provides an assessment of the role and relevance of the UN Watercourses Convention and describes and evaluates its entry into force as a key component of transboundary water governance. To date, the Convention still requires further contracting States before it can enter into force. The authors describe the drafting and negotiation of the Convention and its relationship to other multilateral environmental agreements. A series of case studies assess the role of the Convention at various levels: regional (European Union, East Africa, West Africa, Central Asia, Central America and South America), river basin (e.g. the Mekong and Congo) and national (e.g. Ethiopia and Mexico). The book concludes by proposing how future implementation might further strengthen international cooperation in the management of water resources, to promote biodiversity conservation as well as sustainable and equitable use.

R4,481 Discovery Miles 44 810 Ships in 10 - 15 working days

Does participatory governance benefit the environment? The European Water Framework Directive (WFD), which came into force in 2000 with the aim of revolutionizing European water governance, mandates participatory river basin management planning across the European Union. The belief of European policymakers and the European Commission is that participation will deliver better policy outputs and implementation. This book examines a range of approaches to participatory river basin management planning, and considers whether and how participation impacted on the environmental standard of planning documents, quality of implementation, and social outcomes. It draws on evidence from WFD implementation in eight case studies from Germany, Spain and the United Kingdom on the basis of a matched comparative case study design. The Directive sets common timeframes and procedural requirements, which provides a perfect test-bed and unique opportunity to study the effects of participation on implementation and outcomes in comparative perspective.

A hydroinformatics system represents an electronic knowledge encapsulator that models part of the real world and can be used for the simulation and analysis of physical, chemical and biological processes in water systems, in order to achieve a better management of the aquatic environment. Thus, modelling is at the heart of hydroinformatics. The theory of nonlinear dynamics and chaos, and the extent to which recent improvements in the understanding of inherently nonlinear natural processes present challenges to the use of mathematical models in the analysis of water and environmental systems, are elaborated in this work. In particular, it demonstrates that the deterministic chaos present in many nonlinear systems can impose fundamental limitations on our ability to predict behaviour, even when well-defined mathematical models exist. On the other hand, methodologies and tools from the theory of nonlinear dynamics and chaos can provide means for a better accuracy of short-term predictions as demonstrated through the practical applications in this work.

R5,763 Discovery Miles 57 630 Ships in 10 - 15 working days

The research presented in this work qualitatively investigates the morphodynamic response of a large tidal inlet/basin system to future relative sea level rise (RSLR) using the state-of-the-art Delft3D numerical model. Understanding the potential impacts of RSLR on these systems is a prerequisite for their sustainable management due to their rich bio-diversity and the increase in economic activities and local communities in recent decades.The adopted approach used a highly schematised model domain analogous to the Ameland inlet in the Dutch Wadden Sea. Model simulations were undertaken applying tidal and wave boundary forcings with three IPCC projected RSLR scenarios (no RSLR, low RSLR and high RSLR). Predicted inlet evolution indicated a channel/shoal pattern typically observed at the Ameland inlet. RSLR enhances the existing flood-dominance of the system leading to erosion on the ebb-tidal delta and accretion in the basin. Under the no RSLR case, resulting bed evolution of the process-based model (Delft3D) tends to agree with empirical-equilibrium relations of the ASMITA model. Application of the low RSLR scenario resulted in quite stable tidal flat evolution. Model simulations with the high RSLR scenario indicated disappearing the tidal flats over time and turning the system into a lagoon. Applying nourishment hardly compensated the RSLR induced sediment demand of tidal flat evolution.

Bruce Lankford
R1,610 Discovery Miles 16 100 Ships in 10 - 15 working days

The efficient use of natural resources is key to a sustainable economy, and yet the complexities of the physical aspects of resource efficiency are poorly understood. In this challenging book, the author proposes a major advance in our understanding of this topic by analysing resource efficiency and efficiency gains from the perspective of common pool resources, applying this idea particularly to water resources and its use in irrigated agriculture. The author proposes a novel concept of "the paracommons", through which the savings of increased resource efficiency can be viewed. In effect he asks; "who gets the gain of an efficiency gain?" By reusing, economising and avoiding losses, wastes and wastages, freed up resources are available for further use by four 'destinations'; the same user, parties directly connected to that user, the wider economy or returned to the common pool. The paracommons is thus a commons of - and competition for - resources salvaged by changes to the efficiency of natural resource systems. The idea can be applied to a range of resources such as water, energy, forests and high-seas fisheries. Five issues are explored: the complexity of resource use efficiency; the uncertainty of efficiency interventions and outcomes; destinations of freed up losses, wastes and wastages; implications for resource conservation; and the interconnectedness of users and systems brought about by efficiency changes. The book shows how these ideas put efficiency on a par with other dimensions of resource governance and sustainability such as equity, justice, resilience and access.

The demand on land to produce food, for urban development such as housing, industry, shopping areas, infrastructure and also for recreation has increased during the history of mankind. This has resulted in such activities as the reclamation of swamps, flood plains, tidal areas and even lakes by impoldering. Model simulations can be use to gain insight into the system behaviour of different land use and soil composition under temperate humid and humid tropic conditions, The existing package OPOL, based on a non steady model, was further developed to the version OPOL5 for the simulation of hydrological conditions and optimization of the main components of water management systems in polder areas in the temperate humid and humid tropical zone. This model reveals a system's behaviour as well as the effects of variation in the main components of the systems to the overall costs. For example, the designs of pumped drainage systems in polder areas can be optimized

The challenge of water scarcity as a result of insufficient seasonal rainfall and dry spell occurrences during cropping seasons is compounded by inefficient agricultural practices by smallholder farmers where insignificant soil and water conservation efforts are applied. The hypothesis of this research is that many of the past research efforts have taken a fragmented approach to deal with the challenges facing subsistence farmers in rainfed systems. The research has been conducted in the semi-arid Makanya catchment of northern Tanzania and has successfully applied different analytical techniques to better understand soil and water interactions at field scale. It has been demonstrated that there is indeed scope to increase crop water productivity provided the local farmers adopt more efficient cultivation techniques. Substantial yield increases occur as a result of diverting runoff and these further improve when other techniques such as ripping, application of manure and cover cropping are introduced. This confirms that no single solution exists to solve the problem of low yields in rainfed farming systems. However, even with these promising results, the research has shown that there is room to further improve the efficiency of crop water use through improvement in research approaches and exploration of better techniques.

Water scarcity is increasing all over the world because of growing population and increasing demands. Countries with limited water resources are urgently in need of a new approach toward water management by shifting from the "use and dispose" approach to the "use, treat, and reuse" approach. This book proposes a framework for the sustainable management of scarce water resources. The approach is based on the application of Cleaner Production thinking to water management. This book focuses on the West Bank in Palestine. The West Bank suffers from extreme water scarcity, has (for political reasons) less water than is naturally available, and anticipates an increase in demand for water for reasons of population and economic growth. Therefore, the West Bank needs to shift away from the present approach to water. The book proposes a set of alternatives for sustainable water management in the domestic, agricultural, and industrial sectors in the West Bank. Implementing a combination of water management alternatives as proposed in this book will put water management in the West Bank in Palestine on a sustainable track.

There has been an explosive growth of methods in recent years for learning (or estimating dependency) from data, where data refers to known samples that are combinations of inputs and corresponding outputs of a given physical system. The main subject addressed in this thesis is model induction from data for the simulation of hydrodynamic processes in the aquatic environment. Firstly, some currently popular artificial neural network architectures are introduced, and it is then argued that these devices can be regarded as domain knowledge incapsulators by applying the method to the generation of wave equations from hydraulic data and showing how the equations of numerical-hydraulic models can, in their turn, be recaptured using artificial neural networks. The book also demonstrates how artificial neural networks can be used to generate numerical operators on non-structured grids for the simulation of hydrodynamic processes in two-dimensional flow systems and a methodology has been derived for developing generic hydrodynamic models using artificial neural network. The book also highlights one other model induction technique, namely that of support vector machine, as an emerging new method with a potential to provide more robust models.
