Limnology is an integrated, multidisciplinary scientific study of inland waters – reservoirs, fresh water and saline lakes, ponds, waterways, wetlands, rivers, and groundwater. This book provides a comprehensive these on the current state of the science and an understanding of the bio-geophysical components of inland aquatic ecosystems. The existence of human beings is closely linked to our proximity to freshwater. Despite being of high significance, anthropogenic activities continue to place stressors on inland aquatic ecosystems. An understanding of the natural system allows for predictive analysis and the development of proactive measure to avoid or manage the disturbances to these systems.
