Book Description
Water development projects have altered the environmental flow landscapes where dams and diversions have been built, and this could have effects on coastal resources, particularly in estuaries. Water is an important human resource and water needs grow as populations grow. However, freshwater inflow to the coast is fundamental to the functioning of estuaries. Can we have stable, secure, and sufficient water resources for people and still protect estuarine health? Estuaries are the most productive environments on Earth, and this is in part due to freshwater inflow, which dilutes marine water, and transports nutrients and sediments to the coast. Estuaries are characterized by salinity and nutrient gradients, which are important in regulating many biological processes. As water is diverted for human consumption, it is common for many environmental problems to appear. While many countries have water quality programs, few are dealing with water quantity alterations. The first step is to define marine resources to protect, and the water quality conditions those resources need to thrive. The second step is to determine the flow regimes needed to maintain the desired water quality conditions. Finally, many regions are using adaptive management programs to manage freshwater resources. These programs set goals to protect ecosystem resources, identify indicators, and monitor the indicators over time to ensure that the goals are appropriate and resources are protected. Case studies demonstrate that monitoring and research can determine the ecological and socio-economical impacts of altered freshwater inflows, and stakeholders and managers can make well-informed decisions to manage freshwater inflows to local coasts wisely.

Book Description
Coasts and Estuaries: The Future provides valuable information on how we can protect and maintain natural ecological structures while also allowing estuaries to deliver services that produce societal goods and benefits. These issues are addressed through chapters detailing case studies from estuaries and coastal waters worldwide, presenting a full range of natural variability and human pressures. Following this, a series of chapters written by scientific leaders worldwide synthesizes the problems and offers solutions for specific issues graded within the framework of the socio-economic-environmental mosaic. These include fisheries, climate change, coastal megacities, evolving human-nature interactions, remediation measures, and integrated coastal management. The problems faced by half of the world living near coasts are truly a worldwide challenge as well as an opportunity for scientists to study commonalities and differences and provide solutions. This book is centered around the proposed DAPSI(W)R(M) framework, where drivers of basic human needs requires activities that each produce pressures. The pressures are mechanisms of state change on the natural system and Impacts on societal welfare (including well-being). These problems then require responses, which are the solutions relating to governance, socio-economic and cultural measures (Scharin et al 2016). - Covers estuaries and coastal seas worldwide, integrating their commonality, differences and solutions for sustainability - Includes global case studies from leading worldwide contributors, with accompanying boxes highlighting a synopsis about a particular estuary and coastal sea, making all information easy to find - Presents full color images to aid the reader in a better understanding of details of each case study - Provides a multi-disciplinary approach, linking biology, physics, climate and social sciences

Book Description
Estuarine Ecohydrology focuses on the principal components of an estuary. The book demonstrates how one can quantify an estuarine ecosystem's ability to cope with human stresses. The theories, models, and real-world solutions covered will serve as a toolkit for designing a management plan for the ecologically sustainable development of an estuary. This book is organized into seven chapters dealing with topics such as estuarine water circulation; estuarine sediment dynamics; tidal wetlands; estuarine food webs; and ecohydrology models and solutions. Although each chapter contains rigorous specialist knowledge, it is presented in an accessible way that encourages multi-disciplinary collaboration between such fields as hydrology, ecology and mathematical modeling. Estuarine Ecohydrology is appropriate for use as a textbook and as a reference for researchers; advanced undergraduate and graduate students in marine biology, oceanography, coastal management, and coastal engineering; coastal developers; resources managers, shipping operators; and those involved in estuarine fisheries and sustainable development communities. * Appropriate for use as a textbook and as a reference* Focuses on the principal components of an estuary* Presents theories, models, and real-world solutions to serve as a toolkit for designing a management plan for the ecologically sustainable development of an estuary

Book Description
Estuaries are of high socioeconomic importance with twenty-two of the thirty-two largest cities in the world located on river estuaries. Estuaries bring together fluxes of fresh and saline water, as well as fluvial and marine sediments, and contain high biological diversity. Increasingly sophisticated field observation technology and numerical modeling have produced significant advances in our understanding of the physical properties of estuaries over the last decade. This book introduces a classification for estuaries before presenting the basic physics and hydrodynamics of estuarine circulation and the various factors that modify it in time and space. It then covers special topics at the forefront of research such as turbulence, fronts in estuaries and continental shelves, low inflow estuaries, and implications of estuarine transport for water quality. Written by leading authorities on estuarine and lagoon hydrodynamics, this volume provides a concise foundation for academic researchers, advanced students and coastal resource managers.

Book Description
For the inhabitants of many of the world's major towns and cities, estuaries provide their first and nearest glimpse of a natural habitat. Despite the attempts of man to pollute or reclaim it, the estuarine ecosystem continues to provide a fascinating insight into a natural world where energy is transformed from sunlight into plant material, and then through the steps of a food chain is converted into a rich food supply for birds and fish. The book provides a concise readable introduction to estuarine ecology. First published in 1981, it soon established itself as the principle textbook of choice in the UK & NW Europe. This new edition builds upon the strengths of the earlier editions but has been thoroughly revised throughout. The new co-author brings a human impact dimension to the revised book. It is written for advanced undergraduate and graduate students (particularly taught masters) who have had a general ecology course, but no further training in estuarine science. It will be useful to both professional researchers and practical managers in marine ecology and environmental science who seek a compact but comprehensive introduction to estuarine ecology.
