The sub-discipline of hydrology that deals with the study of interactions between water and ecological systems is termed as ecohydrology. Terrestrial and aquatic systems are studied under its domain. Terrestrial ecosystems include forests and deserts. It involves the interactions among vegetation, the land surface, the vadose zone and the groundwater. Aquatic ecosystems include streams, lakes, rivers and wetlands. It studies 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 contains some path-breaking studies in the field of ecohydrology. The topics included herein are of utmost significance and bound to provide incredible insights to readers. Those with an interest in ecohydrology would find this book helpful.
