      The book introduces the environmental characteristics of river basins and forms and functions of channels commonly seen among the large rivers of the world. Specific discussions cover their complex geology, water, and sediment. The great lengths of these rivers stretch across a range of different environments. The Mekong, for example, flows on both rock and alluvium with varying form and behaviour. The geological framework of a large river is based primarily on large-scale tectonics commonly derived by plate movements. An uplifted zone, the primary source of sediment in the river, and a nearly subcontinental-scale water catchment area are necessary. A range of morphology exists in large rivers, and the associated floodplains and flood pulses are ecologically important. Large rivers could be geologically long-lived. In future, their forms may change and their functions may alter, following construction of engineering structures and climate change.

      The quality of the book has been enhanced by detailed and well-illustrated discussions on two important topics: (i) large rivers and their floodplains: structures, functions, evolutionary traits and management with special reference
