Influence of Sediment Yield Over Life of Reservoir using Arc SWAT, to Adjudge Useful Life of Reservoir by Anova Analysis for Sri Ram Sagar Project

Abstract

Certain issues that include stresses, floods, seismic loads could be observed inevitable and
unpredictable in terms of occurrence, ultimately affect the functionality and life span for any
Reservoir. Another important factor, which ultimately and strappingly influences any robust
Reservoir and its storage capacity is Sedimentation. Appraisal of quantity of sediment and application
of proper remedial measures could significantly sustain and enhance the storage capacity of the
reservoir. This study primarily deals on evaluating the annual sediment deposit in Sri Ram Sagar
Project’s Reservoir using Arc SWAT (Soil and Water Analysis Tool), a plug-in of Arc GIS 10.4. The
attained results from this tool are then compared with Godavari Sediment Year Book (2015–2016) for
validation. Also, the expedient life of this reservoir is calculated using Gill’s Equation. Eventually, the
variance analysis for a difference in deposited sediment and inflow and runoff is evaluated using
Anova Analysis and the results are concluded.
