Abstract

1 Why study tropical rivers?</h5> Large populations in developing economies, chaotic growth of urban areas, a sharp increase in water and power demands, and frequent water-related disasters are some of the common problems in all tropical countries. The resources available and management strategies adopted to tackle these problems, however, may be entirely different from country to country. These differences eventually affect the overall economic growth of the country. For example, millions of farmers in India still practice rather rudimentary agriculture, consuming ~ 80% of total available water. This has obviously resulted in a much lower rate of growth in the agricultural sector in India and has also affected the water and power demands in many parts of the country. Other major concerns in several tropical rivers include river dynamics over decadal scale ( Lahiri and Sinha, this issue ; Rudra, this issue ) and flood disaster. In Asia, the occurrence of floods is recurrent and catastrophic and even though some of the largest rivers of the world drain through South America, flood impacts are not as significant as in Asia and some basins of Africa.</P>Human interventions have affected the natural flows of tropical rivers in many ways (Bawa
