ANALYSIS OF SATELLITE DERIVED MAPS AND HYDROLOGICAL DATA FOR IDENTIFICATION OF NAVIGATION PROBLEMS IN THE BRAHMAPUTRA RIVER

Abstract

The study of navigational problem, is concerned with channel and flow characteristics and plan form pattern of rivers, which include depth, width, velocity, slope, bends, meanders and braiding of the river. Evaluation of channel and flow characteristics and plan form pattern with time and space, is a logical first step towards understanding the behaviour of the river, which enables the navigation managers, planners and designers to take comprehensive decisions as regards the location, type and extent of waterways for effective and balanced utilization of this versatile natural resources for the benefit of the mankind. The Brahmaputra river is one of the mightest rivers in the world and it is the largest river in the Indian subcontinent if compared with respect to length and disch~ i.rge . The 2906 km long river traverses a length of 1625 Km Tibet (China) by the name of Tsangpo, 918 Km in NE India by the name of l]ihang and Brahmaputra, and the rest 363 Km in Bangladesh by the n: ime of Padma and Meghana before outfalling into the bay of Bengal.....
