• Sommario/riassunto: This book focuses on the principal components of an estuary. Although each chapter contains rigorous specialist knowledge, it is presented in an accessible way that encourages multidisciplinary collaboration among such fields as hydrology, ecology and mathematical modeling. Estuarine Ecohydrology demonstrates how one can quantify an estuarine ecosystem's ability to cope with human stresses. The theories, models, and real-world solutions presented will serve as a toolkit for designing a management plan for the ecologically sustainable development of an estuary.* Appropriate for
