Estimation of Suspended Sediment Concentration in Lined Canal

Abstract

This Paper presents estimation of suspended sediment concentration in lined canal. The suspended sediment concentration measurement is been carried out for different discharges including minimum and maximum discharges at one section of Kakrapar Left Bank Main Canal. The bridge method has been used for the collection of suspended sediment water sample. For this purpose, a section selected at Tarsada Highway Bridge which is across the main canal. The total numbers of four; in-site observations were made; many samples of water sediment mixture were taken from the canal section during each observation, these samples were filtered through filter paper and the average suspended sediment concentration recorded. The suspended sediment transport rate was calculated from the observed sediment concentration. The suspended sediment water samples were collected using Punjab bottle sampler. Also for each observation, the water velocity was measured laterally at different point on crosssection by using current meter and the average velocity was computed. The graphs of suspended sediment concentration for different discharges were plotted.
