Extremely high precipitation is characteristic of the frontal zone of the Himalaya. In this article we study tributaries which supply huge sediment loads to the Teesta river in the Darjeeling Himalaya, India and significantly affect transportation regime downstream the junction of the Great Rangit with the main river. The material supply is also conditioned by 70-80% deforestation of the catchment. Will the deepening of the Teesta river and its tributaries follow tectonic movements? Or will the Teesta follow smaller streams that drain the fringe of the Himalaya, and then will the huge foreland cones penetrate the mountain interiors? These questions are important, especially in the context of construction of dams and water reservoirs along the Teesta river and its tributaries.

Abstract


Extremely high precipitation is characteristic of the frontal zone of the Himalaya. In this article we study tributaries which supply huge sediment loads to the Teesta river in the Darjeeling Himalaya, India and significantly affect transportation regime downstream the junction of the Great Rangit with the main river. The material supply is also conditioned by 70-80% deforestation of the catchment. Will the deepening of the Teesta river and its tributaries follow tectonic movements? Or will the Teesta follow smaller streams that drain the fringe of the Himalaya, and then will the huge foreland cones penetrate the mountain interiors? These questions are important, especially in the context of construction of dams and water reservoirs along the Teesta river and its tributaries.
