Sedimentation studies of lotic water (The gang canal) In North-Western Rajasthan, India
Author(s): Rajender Kumar Bishnoi
Abstract: The sedimentation in Gang canal was studied with a specific aim to know its siltation rate, composition of sedimentation and the total sediment deposits that occurred during the existence of the canal for the last 65 years. In the sediments, the total sand was 50 to 95 percent; silt and clay come next in the order of abundance. Within the category of sand, the medium sand ranged from its total absence to 2.5%, very fine sand 17.5% to 37.5% and fine sand was 31%-63%. The gross total annual sediment load comes to 34525.2 MT. Seasonally the load is more during monsoon months followed by winter months and load was lowest summer months. The average deposition per square meter works out to 0.082562 tones/m2/year (i.e.82.562 kg/m2/year). Statistically it was found that each sediment component is directly proportional and thus related to the total sediment. In the case of Gang canal, with its shallowing by the sediment deposition of approximately 60 cm width during last 65 years, the water carrying capacity might have been reduced roughly by 20-30%.
