Quantitative analysis of Nayaseri watershed in the northern slopes of Shimla (Himachal Pradesh, India)
Abstract: The Nayaseri watershed has been analyzed in this research paper using quantitative techniques. This watershed lies in the Northern slopes of Shimla mountainous range and forms the part of Shimla district of Himachal Pradesh. The basin has rocks of tertiary age with beds belonging to the carbonaceous system (Karol and Blaini groups). The metamorphic rocks of the basin consist of mostly black carboniferous, garnetiferous, phyllites, slates, quartzites and highly crushed dolomite. Overall climate of the basin is cool and moist. The pattern of streams in the catchment is pinnate and dendritic mixed with parallel patterns. The linear, areal and relief aspects are involved in quantitative analyses of watershed. The linear and areal investigation of the watershed indicates the incidences of truncation, upliftment, subsidence and tilt in the basin. Hypsometric integral value, elongation ratio, sinuosity index and channel gradient suggest a young stage of landforms development of drainage basin.
