Morphometric analysis of Maun watershed in Tehri-Garhwal district of Uttarakhand using GIS

Proper planning and management of available natural resources is necessary for progress and economic development in agriculture which are main stay of people leaving in the hilly region. The morphometric analysis of watershed coupled with soil, land use and slope can play a vital role in predicting the hydrological behavior of a watershed, engineering and site suitability aspect. An attempt has been made to study the morphometric characteristics of Maun watershed which is located in Tehri-Garhwal district of Uttarakhand. The study area is located between 78 o 22‟ 28” to 78 o 24‟ 57”E longitude and 30 o 17‟ 19” to 30 o 18‟ 52”N latitude and covers an area of 8.71 km 2 . The qualitative analysis of the morphometric characteristics of the basin have been done and computed using GIS software. The drainage network in the study area is dendritic to sub-dendritic which indicates the influence of lithology and terrain on drainage pattern. The results clearly indicate relations among various morphometric attributes of the basin and help to understand their role in sculpturing the surface of the region.
