Abstract: This paper develops a numerical model for the analysis of sediment transport in irrigated channels. The overland flow equation considers infiltration into the subsurface. The model solves Saint Venant and sediment continuity ...

Abstract: Presented herein is a procedure for arriving at an optimal design of a homogeneous earth dam laid on an impervious foundation and provided with a drain. The procedure, heavily dependent on variably saturated flow modeling, ...

Abstract: The present study deals with the analysis of virus transport in groundwater and estimation of transport parameters. The parameter estimation is formulated as a least-squares minimization problem in which the parameters are ...

Abstract: The present study analyses the effect of sodicity on unsaturated soil hydraulic properties. Permeameter and pressure plate experiments were conducted on six texturally different soils at varying sodicity levels to obtain ...

Abstract: The present study addresses the applicability of the crop water stress index (CWSI) derived from canopy temperature to detect the crop water stress of paddy crop. The performance of two artificial intelligence techniques, ...

Abstract: The process of oxygen transfer from the atmosphere to water is termed aeration. Aeration improves the quality of water in streams by replacing dissolved oxygen (DO) consumed in the biodegradation of organic matter. The ...

Abstract: The present study analyzes the effect of salinity on crop growth and root zone soil moisture dynamics. A newly developed root water uptake (RWU) model was used for simulation of soil moisture and RWU for irrigation field ...

Abstract: Riverbank filtration (RBF) is one of the most productive and low-cost technologies for obtaining purified water throughout the year. The inevitable problem associated with RBF is clogging, a complex phenomenon that obstructs ...

Abstract: This study investigates the hazardous effect of salinity on plant growth and soil moisture dynamics in the root zone. Field irrigation experiments on paddy (Oryza sativa L.—basmati variety) with varying levels of salinity ...
