This study was initi~.ted to determine the general effects of potential flow reductions in the middle Snake River (Swan Falls Dam downstream to the Idaho-4)regon border) on its riparian vegetation. Considerable water from the river is currently used to irrigate the adjacent Snake River Plain, and increased demand for water in the future is likely. The problem was subdivided into several researc...

This paper presents the decoupled hydrological discretization (DHD) scheme for solving the shallow water equations in hydrological applications involving surface runoff in rural and urban basins. The name of the scheme is motivated by the fact that the three equations which form the two-dimensional shallow water system are discretized independently from each other and thus, the numerical scheme...

The Mikkes basin is located at the north center of Morocco. It comprises three different zones which represent diversified geologies which shelter a phreatic and confined aquifer in the Sais basin and a shallow aquifer in the Tabular Middle Atlas. The springs in the Sais phreatic aquifer have suffered a maximum depletion. The springs with a deep or mixed origin are known as low flow variation s...

In a shallow channel, the flow transfers most of its momentum vertically. Based on this observation, one often neglects that is transferred across stream – core assumption shallow-water theory. context viscous flows, approximation referred to as ‘lubrication theory’, in which assumes shear stress exerted by fluid substrate over it flows proportional velocity. Here, we revise theory account for ...

In this paper, we study basic properties of the diffusive wave approximation of the shallow water equations (DSW). This equation is a doubly non-linear diffusion equation arising in shallow water flow models. It has been used as a model to simulate water flow driven mainly by gravitational forces and dominated by shear stress, that is, under uniform and fully developed turbulent flow conditions...
