Institutional Access


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.

"...a brilliant synthesis of the state of the art in estuarine ecohydrology ... it opens the perspective for new solutions toward achieving restoration and sustainable development of habitats most intensively used by humanity."
--Maciej Zalewski, Director, UNESCO's European Regional Centre for Ecohydrology

"Wolanski brings vast experience in estuarine and coastal seas research in Oceania and its neighboring regions. The book makes a most valuable contribution to our international activities for coastal seas environments."
--Masahiko Inatsugi, Adviser on External Relations, International Center for the Environmental Management of Enclosed Coastal Seas

"This book provides a deep understanding of the dynamical processes through an ecohydrological approach acting on estuaries."
--Dr. Gerardo M. E. Perillo, Co-Chair SCOR-LOICZ Working Group 122

"LOICZ, at the beginning of its second decade with the mandate to look at coastal change in a truly interdisciplinary fashion strongly endorses the work reflected in 'Estuarine Ecohydrology'. The author provides a substantial contribution to the LOICZ objective, to: provide the knowledge, understanding and prediction needed to allow coastal communities to assess, anticipate and respond to the interaction of global change and local pressure which determine coastal change. It is particularly valuable because its perspectives are truly global in nature, encompassing different views from the developed world as well as from developing economies."
--Dr. Hartwig Kremer, CEO LOICZ IPO.

"This book is particularly timely and highly relevant to the needs of many coastal nations. The author clearly achieves his aim to 'provide clear, specialist knowledge to enable an interaction between aquatic, marine and wetlands biologists, geologists, geomorphologists, chemists, modellers and ecologists'. It is really an interesting book on a very relevant topic."
--Joe Baker, FTSE
