The study of drainage patterns of Suketi River Basin for the proper environmental planning, Mandi District, Himachal Pradesh, India

The Suketi River Basin is situated in lesser Himachal Himalaya,Mandi district H.P. In the study of proper environmental planning of rivers patterns playa dominant role due to its self sustained ecological cycles which make changes in landscapes morpho-units. The Suketi River Basin is drained by the Suketi River and its numerous tributaries, the main among these are Vmli Khar Jatla Nallah, Bonyat Nallah, Gambhar Khad, Bhadyal Nallah, Gagal Nallah and Chadyam Nallah etc. The area up to Dhasni village south of the locality of Chela village the Suketi River flows in to a broad "U" shape valley from 400m to 600m wide with unsorted sediments of all the grades. To prepare base map from SOl Toposheets within 1:50000 scale. In drainage analysis the Strahler's stream -segment method of stream order has been applied. To demarcate the Suketi River Basin prepared various thematic layers of river basin and its tributaries. The study objectives came into a final target that the nature and type of environmental resources depletion, hydrological planning and pinpoint the intensity and distribution of depleting factors to treat them with ecological measures and to develop a technique for finding out the suitability of landforms for varied uses in the context with environment development.
