Strains among the states of Central Asia over using the region’s scarce water resources are increasing. A major controversy is Rogun dam (RD) on the Vakhsh River, a tributary of the Amudarya River. The intent of RD is to supply energy revenue for Tajikistan, but a side effect may be the agricultural sector of Uzbekistan. Future water shortage may cost Uzbekistan over US $600 million annually in losses from...

The effect of inclined groins on the flow
Hydraulic structures, such as pile dikes, groins, splitting dikes, have been constructed in natural rivers to improve the channel stability to bank or bed erosions by reducing flow velocity or changing flow direction. In order to produce better river environments, river flow mechanisms with the hydraulic structures need to be intensively studied. In this paper, an experimental flow field with non-overflow groins in a...
