TRAINING AND CONTROL OF HIMALAYAN RIVERS FOR FEEDING IRRIGATION CANALS WITHOUT PERMANENT DIVERSION WORKS - A CASE STUDY OF UPPER CAN GA CANAL

Abstract

The Himalaya exercises a dominant influence on meteorological conditions over the Indian subcontinent as well as on its physical geography and they virtually affect the entire area and its water circulation system. Vast reservoir of water in the form of ice, snow fields and glaciers, give rise to many large rivers and innumerable streams which constitute three major rivers viz. the Brahamputra, the Ganga and the Indus.
