Water discharge and suspended sediment dynamics in the Chandra River, Western Himalaya

摘要: Glacier systems are important components of the hydrological cycle and a major source meltwater sediment flux that controls river ecology, water quality, hydropower generation in Indian Himalayan Region (IHR). Thus, understanding short- long-term changes suspended (SS) dynamics is crucial highly sensitive pro-glacial Rivers. In present study, Chandra River basin Western Himalaya was chosen to study discharge, SS transport dynamics, physical erosion rate, their governing factors for 2017 melting season (May–September). The daily mean discharge concentration 260.7 m3s−1 775.5 mgL−1 with maximum month July. air temperature showed significant relationship (R2 = 0.67; n 156; p 100 km) from upper glacierized region end basin. Statistical analysis particle size poorly sorted immature grains dominance silt particles (85%), followed by sand (8.5%) clay (6.5%). estimates revealed total yield 1285 tons km−2 yr−1 rate 0.47 mm yr−1. Considering socio-economic importance region, will help evaluate budget River, establish meteorological conditions
