Ecohydrology is a scientific field that is concerned with the study of interactions between water and ecological systems. Studies related to both terrestrial and aquatic systems fall under this domain. Terrestrial ecosystems, such as forests and deserts facilitate the interactions among vegetation, the land surface, the vadose zone and the groundwater. Aquatic ecosystems such as streams, lakes, rivers and wetlands are studied to understand how their structures and functions are affected by water chemistry, geomorphology and hydrology. Transpiration and plant water use, the adaption of organisms to their water environment, the influence of vegetation and benthic plants on streamflow, are some of the main areas of research of this discipline. This book studies, analyzes and upholds the pillars of ecohydrology and its utmost significance in modern times. Also included herein is a detailed explanation of the various concepts and applications of this field. This book is appropriate for students seeking detailed information in this area as well as for experts.
