The agriculturally productive San Joaquin Valley faces two severe hydrologic issues: persistent groundwater overdraft and flooding risks. Capturing flood flows for groundwater recharge could help address both of these issues, yet flood flow frequency, duration, and magnitude vary greatly as upstream reservoir releases are affected by snowpack, precipitation type, reservoir volume, and flood ris...

Control of sedimentation in reservoirs of dams is considered to be one of the most important issues in exploitation of dams and increasing their useful life. Reservoirs act as traps for sediments and prevent transport of sediments to the river. The deposited sediments will decrease the capacity of the reservoirs so that they cannot be in use any more. Various methods are discussed in this study...

Flow field in shallow waters, which is characterized by its complex mixing process and inherent dynamic nature, is interesting mainly due to its practical importance (e. g. in free flushing operation and sedimentation in large reservoirs). 3D numerical models make it possible to track two-dimensional large turbulence coherent structures, which are the dominant phenomenon in shallow reservoirs f...

The article presents the results of analysis deep deformations Amu Darya riverbed in upper reaches low-pressure reservoir. combined transverse profiles different sections Takhiatash reservoir showed that coastal zones are most intensively silted up. At same time, core zone with highest flow rates is very weakly declared. height silting layer along length stream increases direction dam. area ext...

With ever decreasing potential for suitable new dam sites, sustainable use of existing water reservoirs is paramount importance. In absence appropriate measures, reservoir storage continually reduced due to sedimentation. One option remove sediment deposits hydraulic flushing. During the flushing operation, bottom outlets are open and released. Whether successfully removes depends on a number f...
