Applied methodology based on HEC-HMS for reservoir filling estimation due to soil erosion

Abstract Authors propose a beneficial methodology for hydrological planning in their study. Prospective evaluations of the basins’ net capacity can be done using technique presented. The HEC-HMS (Hydrologic Modelling System) software used to estimate basin, sediment emitted. For certain precipitation, this allows estimating, within range, gradual blockage reservoir, and even projected date total blockage. This has some applications adopt corrective measures that prevent or delay planned deadlines. model is semi-distributed type, estimating generation emission sediments by sub-basins. integration different return periods with sub-basins application mathematical are differentiating element research. novelty work allow prognosing reservoir sedimentation rate basins local regional scale medium large temporary framework. developed public institutions take decisions concerning planning. It been applied case “Charco Redondo” Cádiz, Andalusia, southern Spain. Applying case, an average soil degradation basin estimated. Therefore, it verified 50 years expected lose 8.4% its capacity.
