This book gives a comprehensive account of the biology and ecology of rivers. It has chapters dealing with the physical properties of rivers; interaction of river water with ground water; presence of viruses, bacteria, algae, fungi, higher plants and animals in rivers; downstream gradients in river and the type of fish; fishes of swamp and marsh; food webs in rivers; physical and chemical properties of the habitats like visible radiations, nutrients, dissolved oxygen, pH, sediments, current and temperature affecting the ecology of water, the flora and the fauna; the flood in rivers; hydroelectric power; biomonitor of water; water pollution; and control of water pollution. Each topic is illustrated with line drawings. The book would help in promoting ecological understanding of structure and functioning of river ecosystem and getting insights to assess and minimize negative human aspect on the integrity of river ecosystem. The book provides the basic knowledge to evaluate the river and stream ecosystem for environmental protection and conservation issues and for assessing potential environmental impacts caused by pollution, structural deficits, introduced species, flood prevention, construction measures, hydroelectric reservoirs, etc.
