Treatment of expansive soils with quality saline pore water by cyclic drying and wetting
Expansive soils can be found in many parts of the world particularly in arid and semi-arid regions. These soilspose a significant hazard to civil engineering structures due to its high swelling and shrinkage potential. This paperpresents the results of an experimental program developed to investigate the effect of cyclic drying and wetting on theswelling potential of expansive soils with variou...
متن کاملA wetting and drying scheme for POM
In shallow-water models, wetting and drying (WAD) are determined by the total water depth D 1⁄4 0 for ‘dry’ and >0 for ‘wet’. Checks are applied to decide the fate of each cell during model integration. It is shown that with bottom friction values commonly used in coastal models, the shallow-water system may be cast into a Burger’s type equation for D. For flows dominated by D (i.e. jrDj jrH j,...
متن کاملA wetting and drying scheme for ROMS
The processes of wetting and drying have many important physical and biological impacts on shallow water systems. Inundation and dewatering effects on coastal mud flats and beaches occur on various time scales ranging from storm surge, periodic rise and fall of the tide, to infragravity wave motions. To correctly simulate these physical processes with a numerical model requires the capability o...
متن کاملStandardization of alternate wetting and drying (AWD) method of water management in low land rice (Oryza sativa (L.))
Alternate wettting and drying (AWD) systems save water compared with continuoussubmergence (CS) irrigation. However, the reported effect on yield varies widely and detailedcharacterizations of the hydrological conditions of AWD experiments are often lacking so thatgeneralizations are difficult to make. We compared the effects of AWD and CS on crop andwater productivity in rice in the field expe...
متن کاملLocally Limited and Fully Conserved RKDG2 Shallow Water Solutions with Wetting and Drying
This work extends a well-balanced second-order Runge-Kutta discontinuous Galerkin (RKDG2) scheme to provide conservative simulations for shallow flows involving wetting and drying over irregular topographies with friction effects. For this purpose, a wetting and drying technique designed originally for a finite volume (FV) scheme is improved and implemented, which includes the discretization of...
