RISEffect of Infiltration on Sediment Transport in Irrigated Channels
Publisher: American Society of Civil Engineers
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 ...
Seepage Modeling Assisted Optimal Design of a Homogeneous Earth Dam: Procedure Evolution
Publisher: American Society of Civil Engineers
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, ...
Analysis of Virus Transport in Groundwater and Identification of Transport Parameters
Publisher: American Society of Civil Engineers
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 ...
Effect of Sodicity on Soil–Water Retention and Hydraulic Properties
Publisher: ASCE
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 ...
Comparison of the Self-Organizing Map and the Adaptive Neuro-Fuzzy Inference System in Predicting the Paddy Crop Water Stress Index
Publisher: American Society of Civil Engineers
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, ...
Effect of Salinity on Moisture Flow and Root Water Uptake in Sandy Loam Soil
Publisher: ASCE
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 ...
Effect of Clogging on Riverbank Filtration: An Experimental Analysis Using Ganges Riverbed Sediment
Publisher: ASCE
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 ...
Effect of Salinity on Crop Growth and Soil Moisture Dynamics: A Study with Root Water Uptake Model
Publisher: ASCE
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 ...
Optimal Well Location in a River Bank Filtration System: Sensitivity to Aquifer Characteristics and Decay Rate
Publisher: American Society of Civil Engineers
Estimation and Characterization of Deep Percolation from Rice and Berseem Fields Using Lysimeter Experiments on Sandy Loam Soil
Publisher: American Society of Civil Engineers
Abstract: Deep percolation from the root zone of water intensive crops reduces irrigation efficiency, minimizes water productivity and becomes an environmental threat by carrying chemical residues to groundwater systems. Quantification ...
