Water and other fluid pipes that are placed on the seabed and rivers bed change the flow pattern around them. These changes increase the shear stress of the bed and the severity of turbulence around the pipe and create a ...

Saturated hydraulic conductivity (KS) can be determined with correlation or hydraulic methods. Hydraulic methods can be classified as laboratory and large-scale or small-scale in-situ methods. Auger-hole, inversed auger-hole ...

High flow discharges coming from the hydraulic structures usually carry a high-velocity jet of flow, which could have different short- and long-term impacts on the river mechanics and the habitat conditions. Scouring is ...

The drying of lakes and wetlands is a significant challenge to the hydrological cycle of resources, to human life, and to animal and plant species. The bed soils of lakes in arid and semi-arid regions become dry and wet ...

In this paper, the quarter-circular crested stepped spillway (QCSS) is introduced and its hydraulic properties including the discharge coefficient (Cd) and energy dissipation of flow are investigated. The QCSS consists of ...

There are many slopping lands in Chaharmahl-Bakhtiari Province of Iran, located in the central Zagros, which have suitable conditions for production of rain-fed horticultural products. This study was an attempt to determine ...
