Landform Analysis and Soil Resource Inventory Using Remote Sensing Technique in a Watershed of Uttaranchal, India

چکیده
The IRS-1D LISS III false colour composite (FCC) decoded imagery belonging to Kosi river watershed of Almora district of Uttaranchal under warm humid Lesser Himalayan agro-ecological region was interpreted and surveyed for soil resource mapping. On the basis of image interpretation and ground truth study ten physiographic units were identified. Soil physiography relationship was established on correlation of the soil-site characteristics and physico-chemical properties of soils. Based on the image characteristics and soil-physiography relationship soil map of the area was prepared. The study revealed that the remote sensing technique was useful in delineating physiographic units and inventory of soil resources in remote/inaccessible areas of mountainous lands, which are important for watershed management as well as agricultural development of an area.
