this paper describes the problem of sedimentation in reservoirs,in general, and offers an estimate of the annual rate of storage loss and the useful life of sefidrud reservoir in iran,in particular. the life of sefidrud reservoir was predicted to exceed 100 years in the design, based on insufficient data. regular daily measurements of sediment discharge of the river, taken years later, however,...

Abstract Modeling reservoir sedimentation is particularly challenging due to the simultaneous simulation of shallow shores, tributary deltas, and deep waters. The upstream parts reservoirs, where deltaic avulsion erosion processes occur, compete with validity modeling assumptions used simulate deposition fine sediments in We investigate how complex numerical models can be calibrated accurately ...

The Conowingo Reservoir is situated on the Susquehanna River, immediately upstream of Chesapeake Bay, the largest estuary in the United States. Sedimentation in the reservoir provides an unintended benefit to the bay by preventing sediments, organic matter, and nutrients from entering the bay. The sediment storage capacity of the reservoir is nearly exhausted, however, and the resulting increas...

hydro-induction sediment discharge technique (hsdt) aims to prevent reservoir sedimentation by withdrawing the discharge water from the reservoir bottom to suck up and discharge sediments, and by inducing vertical vortexes and undercurrents in the reservoir bay to keep sediments agitated and moving. the technique is facilitated with an innovative discharge conduit system having bottom intakes t...

Hydro-induction sediment discharge technique (HSDT) aims to prevent reservoir sedimentation by withdrawing the discharge water from the reservoir bottom to suck up and discharge sediments, and by inducing vertical vortexes and undercurrents in the reservoir bay to keep sediments agitated and moving.

Abstract Theoretical and empirical equations have previously been proposed to compute the sediment trap efficiency of a reservoir. The were developed by analyzing limited amount field data for reservoirs in selected areas; thus, their suitability is restricted regions with similar hydrological characteristics. In this study, trap-efficiency equation, which accounts dynamic behavior sedimentatio...

This paper proposes the Marine Predators algorithm (MPA) linked with reservoir simulation model and considering sedimentation, in order to improve rule curves. The release criteria of hedging (HR) standard operating policy (SOP) were investigated this study. results showed that patterns new optimal curves from MPA technique sedimentation using HR practically useful study, as SOP those existing ...
