III-7-Preliminary Investigations on Dhansiri (South) River Basin in NE India.

Abstract

Water resources management practice deals with occurrences, distribution, movement and properties of water on the earth and their environmental relations. Hydrological processes are quite complex in nature and show wide variation in space and time. A basic understanding of hydrology and characteristics of basin such as soil type. vegetation, land use, geology etc. are fundamental to the water resources programme of any region. Knowledge of basin hydrology essentially proceeds for planning and operation of any water resources development and watershed management program in the basin. North eastern region in India has the herculean task to efficiently plan for development or management of its huge water resources constituting about one third of the total potential of the country for want of sufficient data/information of the basins and sub-basins which are mostly ungauged as yet. In the present paper, an attempt has been made to provide the basic hydrological information of Dhansiri (south) river basin of NE region for efficient water resources management.
