Abstract

In this study, an assessment of physical and chemical load, sediment yield and erosion rate has been undertaken at 8 different locations in the Sainj and Tirthan watersheds. The analysis revealed that the maximum load was transferred during the monsoon season. Moreover, the estimated average chemical erosion rate of the Sainj and Tirthan watersheds were higher than that of the Indian average representing all the rivers. Both watersheds were eroding physically and chemically at a faster rate than that of the world global average erosion rate. The flattish nature of the channels in some segments of these watersheds showed a lower transport of sediments, where as the constricted segments having steep bed slopes increased the velocity of flow and the sediment transport rate. These findings have important implications for water resource management
