The study of interactions between water and ecological systems fall under the domain of ecohydrology. The interactions between water and ecological systems occur within the water bodies like lakes and rivers. Such interactions can also occur on land, such as in forests, deserts and other terrestrial ecosystems. Ecohydrology focuses on diverse areas such as, transpiration and plant water use, effects of vegetation and benthic plants on stream flow and adaptation of organisms to their water environment. Ecohydrology studies both terrestrial and aquatic ecosystems. Its main focus in terrestrial ecosystems is on the interaction among vegetation, the vadose zone, land surface and the groundwater. In aquatic ecosystems, it emphasizes on the effects of geomorphology, water chemistry and hydrology on the structure and function of the ecosystem. This book unravels the recent studies in the field of ecohydrology. It elucidates the concepts and innovative models around prospective developments with respect to ecohydrology. It will provide comprehensive knowledge to the readers.
