Sedimentation Analysis on Reservoir (A Case Study of Sukkur Barrage) A Case Study of Sukkur Barrage

Abstract

A study was conducted on the 145 largest rivers in the world with consistent long-term sediment records, and the findings indicate that 50% of the rivers statistically tend towards significantly lower flow because of sedimentation. According to reports, the global reservoir gross storage capacity is approximately 6000 km3 and annual reservoir sedimentation rates are approximately 31 km3 (0.52%). This indicates that by the year 2100, the capacity of the world's reservoirs will have been reduced by 50% due to sedimentation. Since Sukkur Barrage is one of the largest and severely affected reservoirs in Pakistan so this paper will discuss different causes and patterns of sediment deposition which occurred at Sukkur Barrage.
