The study of the Himalayan Rivers is relatively new in the area of hydrological research. These unique rivers with their large number of tributaries run down from their abode the Himalayas. The Himalayas, being a newly formed loose and fragile rocked and heavy monsoonal rain, are the reasons behind the heavy silt load and huge volume of water of these rivers. This book imparts the ever-changing aspects of the Himalayan Rivers like floods of high magnitude, shifting of river courses, frequent occurrence of landslides, bank erosion etc. The book also highlights the aspect of flood adaptability and flood management, giving emphasis on the idea of ?living with flood? in a self-adaptive approach and also about flood forecasting and floodplain zoning. It is thus very needful for one and all to understand the dynamic river systems with geographical promises.
