Assessment of sediment accumulation and capacity of reservoir by analytical approach--a case study.
Sedimentation in reservoirs is a major problem in all countries. A study on sediment accumulation in a reservoir is necessary for effective reservoir planning and watershed management systems. In this study, the volume of sediment deposition in the Vaigai reservoir is calculated based on the analytical approach. The historical water inflow for the years 1959 to 1999 (41 years) are used to calculate the water inflow for future years. The volume of sediment accumulation in the reservoir is predicted using the calculated water inflows. Based on the volume of sediment accumulation, the capacity of reservoir and the percentage of loss in capacity were also calculated. The result obtained from the analytical method is compared with the actual capacity of reservoir and found that the calculated values match well with the actual results.
