The study of wetlands is a relatively new field and the modelling of these systems is still in its formative stages. Nevertheless, the editors felt compelled to assemble this volume as a first statement of the state of the art of modelling approaches for the quantitative study of wetlands. A global approach has been adopted in this book, not only by including a wide geographic distribution of wetlands, but also by including papers on both freshwater and saltwater wetlands. Wetlands are defined as systems intermediate between aquatic and terrestrial ecosystems, and include ecosystems under a wide range of hydrologic and ecologic conditions. The wetland types discussed in this book reflect that heterogeneity, ranging from intermittently flooded wet meadows to permanently flooded shallow reservoirs and lakes. Also included are modelling examples from coastal salt marshes, shallow estuaries, mesotrophic bogs, reedswamps, forested swamps, and regional wetlands. In summary, the book presents ecological modelling as a tool for management of these sensitive ecosystems, and for studying their structure and function. Each chapter has extensive references related to the modelling approach and wetland type discussed. It will be useful for wetland scientists and managers, and could also serve as a supplemental text on courses in wetland ecology.

Wetlands are complex and dynamic ecological systems incorporating two important, inter-linked components: hydrology and vegetation. Modelling wetland components and processes reveals the nature of wetland systems and helps to predict the effects of environmental change. The main goal of much current research is the construction of a vigorous and sp

Ecological modelling has developed rapidly in recent decades, with the focus primarily on the restoration of lakes and wetlands. Ecological Modelling and Engineering in Lakes and Wetlands presents the progress being made in modelling for a wealth of applications. It covers the older biogeochemical models still in use today, structurally dynamic models, 3D models, biophysical models, entire watershed models, and ecotoxicological models, as well as the expansion of modeling to the Arctic and Antarctic climate-zones. The book also addresses modelling the effect of climate change, including the development of ecological models for addressing storm water pond issues, which are increasingly important in urban regions where more concentrated rainfalls are a consequence of climate change. The ecological engineering topics covered in the book also emphasize the advancements being made in applying ecological engineering regimes for better environmental management of lakes and wetlands. Examines recent progress towards a better understanding of these two important ecosystems Presents new results and approaches that can be used to develop better models Discusses how to increase the synergistic effect between ecosystems engineering and modelling

Wetlands are very sensitive and valuable ecosystems that are subject to much stress from human activities. The study presented here has developed an innovative triple layer framework for analysis of wetland management. This approach provides support for spatial matching between physical planning, hydrological and ecological processes, and economic activities. The authors describe how integrated modelling at the regional scale can be achieved in practice. Following an introduction to wetlands, theoretical aspects of the contributing disciplines are discussed, as well as various aspects of integrated and spatial modelling. An applied integrated assessment of spatial wetland management for the Vecht area between Amsterdam and Utrecht is then presented. This assessment has resulted in a set of linked hydrological, ecological and economic models, formulated at the level of grids and polders, and various types of evaluations and rankings of scenarios. The results indicate the value of maintaining spatial detail for as long as possible.

Around 6% of the Earth's land surface is covered by wetlands. Wetlands play a key role in hydrological and biogeochemical cycles, delivering multiple benefits to society: sources of water supply, flood regulation, water purification, agriculture, fisheries, and biodiversity. Hence, wetland systems are of immense socio-economic as well as ecological importance. In this research, the focus was on the Abras de Mantequilla (AdM) wetland in the tropical coastal region of Ecuador, a RAMSAR site and case study area for the EU-FP7 WETwin project. The research in this thesis involves a combination of field data collection, multivariate analysis techniques, as well as numerical modelling studies. The goal was to explore the effects of changes in hydrological forcing on the hydrodynamic and ecohydraulic responses of the wetland. The study aims to contribute to the understanding of how a tropical river-wetland system functions in terms of hydrodynamics, water quality, primary production, and biotic communities. Spatial patterns of biotic communities and environmental variables are obtained as well as spatio-temporal variability of hydrodynamics, water quality, primary productivity and fish habitat-suitability conditions. In data scarce areas and countries with financial constraints, the combination of field measurements with numerical models was extremely useful and relevant, confirming that these techniques complement each other in obtaining a better understanding of the dynamics of freshwater river–wetland systems. Studies like the present research can be used to enhance awareness about the environmental services of wetlands and stimulate cooperation between all stakeholders in order to achieve more sustainable wetland management.

With a sharp focus on environmental pollution and its impact on life and nature, scientists and engineers have studied the water treatment effect of natural wetlands for many years, resulting in the development of constructed wetlands (CWs) for treating wastewater. This informative new book provides current information and guidance on the construction, performance, operation, and maintenance of subsurface flow constructed wetlands of domestic and municipal wastewater. The focus of the volume is to evaluate the performance of horizontal subsurface flow constructed wetlands in treating domestic wastewater to establish the limit that can be safely discharged to agricultural drains. Two-step procedures were used for the preparation of this book. Using modeling and statistical analyses of treated water samples showed a significant difference between different media for the treatment of most pollutants. The authors went on to design artificial neural network models (ANNs) using Matlab software to simulate some of the experimental data and to anticipate the parameters of output concentration. The wetland systems have the ability to deal with various pollutants with different concentrations and to decrease the treated water to the standard limits. This volume presents the main role of emergent plants for treatment performance in the constructed wetlands and will be a very important resource for engineers in this field as well as for both undergraduate and graduate students.

Estuaries and Wetlands are important coastal resources which are subject to a great deal of environmental stress. Dredging, construction, creation of intertidal wetlands, regulation of fresh water flow, and pollution are just a few of the activities which affect these coastal systems. The need to predict the effects of these perturbations upon ecosystem dynamics, particularly estuarine fisheries, as well as on physical effects, such as sedimentation and salt intrusion, is of paramount importance. Prediction requires the use of models, but no model is likely to be satisfactory unless fundamental physical, chemical, sedimentological, and biological processes are quantitatively understood, and the appropriate time and space scales known. With these considerations in mind, the Environmental Laboratory, U. S. Army Engineer Haterways Experiment Station,* Vicksburg, Mississippi, sponsored a workshop on "Estuarine and Wetland Processes and Water Quality Modeling" held in New Orleans, June 1979. The contents of this volume have been selected from the workshop papers. The resulting book, perhaps more than any other symposium proceed ings on estuaries and wetlands, attempts to review important pro cesses and place them in a modeling context. There is also a distinct applied tinge to a number of the contributions since some of the research studies were motivated by environmental assessments. The difference in title between this volume and the workshop re flects more accurately the contents of the published papers.

Ecosystem Response Modelling in the Murray-Darling Basin provides an overview of the status of science in support of water management in Australia's largest and most economically important river catchment, and brings together the leading ecologists working in the rivers and wetlands of the Basin. It introduces the issues in ecosystem response modelling and how this area of science can support environmental watering decisions. The declining ecological condition of the internationally significant wetlands of the Murray-Darling Basin has been a prominent issue in Australia for many years. Several high profile government programs have sought to restore the flow conditions required to sustain healthy wetlands, and this book documents the scientific effort that is underpinning this task. In the Southern Murray-Darling Basin, the River Murray, the Murrumbidgee River and their associated wetlands and floodplains have been the focus of the Murray-Darling Basin Authority's 'The Living Murray' program, and the NSW Rivers Environmental Restoration Program. The book documents research aimed at informing environmental water use in a number of iconic wetlands including those along the Murray - the Barmah-Millewa Forest; the Chowilla Floodplain and Lindsay-Wallpolla Islands; the Coorong and Murray mouth; and the Murrumbidgee - the Lowbidgee Floodplain. Within the Northern Murray-Darling Basin, research conducted in support of the Wetland Recovery Plan and the NSW Rivers Environmental Restoration Program has improved our knowledge of the Gwydir Wetlands and the Macquarie Marshes, and the water regimes required to sustain their ecology.
