Axial Dispersion Coefficients in Laminar Flows of Water-Distribution Systems
Publisher: American Society of Civil Engineers
Abstract: Because longitudinal dispersion is becoming increasingly germane to the problem of accurately determining water quality, water-resource managers and engineers seeking to represent solute transport in drinking-water systems ...
Momentum Transport Mechanism for Water Flow over Porous Media
Publisher: American Society of Civil Engineers
Abstract: The momentum transport phenomena at the interface of the porous medium and fluid have been numerically investigated. The single domain approach is used with matching boundary conditions; that is, the Brinkman-Forchheimer-extended ...
Enhanced Artificial Neural Networks Estimating Water Quality Constraints for the Optimal Water Distribution Systems Design
Publisher: American Society of Civil Engineers
Experimental Verification of Incomplete Solute Mixing in a Pressurized Pipe Network with Multiple Cross Junctions
Publisher: American Society of Civil Engineers
Abstract: Water quality models based on accurate mixing data at cross junctions are important for estimating concentrations of chemical species in municipal water distribution systems. Recent studies indicate that the instantaneous ...
Heuristic Postoptimization Approaches for Design of Water Distribution Systems
Publisher: American Society of Civil Engineers
Abstract: This work presents a postoptimization methodology for refining the solutions found by adaptive search algorithms used in the design of large water distribution networks. The approach uses two heuristics to search for an ...
Estimating Soil Moisture Under Low Frequency Surface Irrigation Using Crop Water Stress Index
Publisher: American Society of Civil Engineers
Abstract: The present study investigated the relationship between the crop water stress index (CWSI) and soil moisture for surface irrigated cotton (
Comparison of Crop Contamination by Microorganisms during Subsurface Drip and Furrow Irrigation
Publisher: American Society of Civil Engineers
Abstract: This study was conducted to compare subsurface drip irrigation (SDI) with furrow irrigation (FI) in crop contamination with microbial-contaminated water irrigation.
Bacteriophages MS2 and PRD1 in Turfgrass by Subsurface Drip Irrigation
Publisher: American Society of Civil Engineers
Abstract: The contamination of turfgrass by bacteriophages MS-2 and PRD-1 was assessed in the field under sprinkler irrigation (SI) and subsurface drip irrigation (SDI). No contamination of turfgrass by MS-2 was observed using SDI ...
Water Stress Detection Under High Frequency Sprinkler Irrigation with Water Deficit Index
Publisher: American Society of Civil Engineers
Abstract: A remote sensing package called the agricultural irrigation imaging system (AgIIS) aboard a linear move irrigation system was developed to simultaneously monitor water status, nitrogen status, and canopy density at one-meter ...
