Book Description
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.

Book Description
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

Book Description
Estuaries are among the most biologically productive ecosystems on the planet--critical to the life cycles of fish, other aquatic animals, and the creatures which feed on them. Estuarine Ecology, Second Edition, covers the physical and chemical aspects of estuaries, the biology and ecology of key organisms, the flow of organic matter through estuaries, and human interactions, such as the environmental impact of fisheries on estuaries and the effects of global climate change on these important ecosystems. Authored by a team of world experts from the estuarine science community, this long-awaited, full-color edition includes new chapters covering phytoplankton, seagrasses, coastal marshes, mangroves, benthic algae, Integrated Coastal Zone Management techniques, and the effects of global climate change. It also features an entriely new section on estuarine ecosystem processes, trophic webs, ecosystem metabolism, and the interactions between estuaries and other ecosystems such as wetlands and marshes

Book Description
It is estimated that roughly 1000 new ecological and environmental models join the ranks of the scientific literature each year. The international peer-reviewed literature reports some 20,000 new models spanning the period from 1970-2010. Just to keep abreast of the field it is necessary to design a handbook of models that doesn't merely list them,

Book Description
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.

Book Description
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
