Sediment delivery to reservoirs causes a reduction in storage capacity, leading to emergency water conditions and difficulties in managing water resources and dams, especially on dry land. In this paper, a methodology for calculating the time period of sedimentation-induced operational failures of a water supply dam, based on the reservoir’s daily water balance equation, is presented. The method applies a shot noise stochastic model to generate daily streamflow data calibrated with historical data and accounts for sedimentation rates and the water volumes supplied to users. A Monte Carlo simulation was employed to generate different combinations of inflow and water supply release scenarios.

Abstract

Sediment delivery to reservoirs causes a reduction in storage capacity, leading to emergency water conditions and difficulties in managing water resources and dams, especially on dry land. In this paper, a methodology for calculating the time period of sedimentation-induced operational failures of a water supply dam, based on the reservoir’s daily water balance equation, is presented. The method applies a shot noise stochastic model to generate daily streamflow data calibrated with historical data and accounts for sedimentation rates and the water volumes supplied to users. A Monte Carlo simulation was employed to generate different combinations of inflow and water supply release scenarios. The proposed methodology, which is completely generalizable, was applied to the Camastra reservoir case study in southern Italy. The results were in good agreement with the reservoir’s historical operational data.
