Abstract

Reservoir siltation is inevitable because of continuous deposition of silts, pollutants etc due to soil erosion from upstream part of river and domestic / industrial waste intrusion in the river. The pace of siltation process can only be retarded which would indirectly aid to life of the reservoir. This paper presents a study on the future storage capability along with reliability in the serviceability of the Maithon reservoir, India. The surveyed capacity elevation data for the year 1956, 1965, 1971, 1979, 1987, 1994, 2002 and 2010 were considered for the analysis. A graphical relation for storage loss at different stages such as dead storage, live storage, flood storage level and overall capacity loss are presented. Mathematically linear trend equations of the above relations are developed with vide validation with the original surveyed data. From the above equations the loss of storage capacity in the future years are also found out at the various stages of the reservoir storage.
