Computational Simulation of the Flow Induced by Water Leaks in Pipes
(American Society of Civil Engineers, 2023/06/01)Despite recent advances in leak detection in water supply systems, previous studies focused mainly on material aspects or orifice opening characteristics. This study evaluated geometric, hydraulic, and hydrodynamic factors ... -
Soil Moisture Content from Spectral Reflectance Using Visible, Near-Infrared, and Short-Wave Infrared Light
(American Society of Civil Engineers, 2023/06/01)Quantification of soil moisture content is important for understanding physical processes that occur on and within the earth. The methods that are currently used for the determination of soil moisture content are point-based ... -
Hydraulic Capacity of Bend Manholes for Supercritical Flow
(American Society of Civil Engineers, 2023/02/01)Sewer bend manholes are frequent elements of urban drainage systems. Any deviation of straight-lined supercritical flow, as within the manhole, generates shock waves, possibly impinging at the manhole end or imposing a ... -
Reducing Sediment Deposition on Columned Vortex-Settling Basin Floor by Installing Vanes
(ASCE, 2022/12/01)Vortex-settling basins (VSBs) have been constructed with support columns under the deflector to enhance the structural stability of the deflector. This paper presents a retrofit for such columned VSBs by installing vanes ... -
Computational Fluid Dynamics–Based Evaluation and Verification of FISP Suspended Sediment Samplers
(ASCE, 2022/12/01)Suspended sediment concentration is critical for many aspects of water resources management, such as sedimentation prevention in irrigation channels. Samplers from the Federal Interagency Sedimentation Project (FISP) are ... -
Designing Trickle Irrigation Systems in Sloping Fields without Pressure-Compensating Emitters: Application of the IRRILAB Software
(ASCE, 2022/12/01)When designing trickle irrigation systems in sloped fields, the use of pressure-compensating (PC) emitters is generally preferred to ensure the emitter distribution uniformity regardless of the land topography and the ... -
Calibration of Free-Flow Radial Gates with Refined Energy Relations
(ASCE, 2022/10/01)Laboratory experiments were conducted on a radial gate to evaluate the energy equation for free-flow calibration. The experiments were used to develop new equations for the radial gate contraction coefficient for free flow. ... -
Effect of Geonet on Scour Downstream of Horizontal Jets
(ASCE, 2022/10/01)In river engineering, scouring around hydraulic structures constructed on erodible beds is highly attractive because of its impact on the stability of these structures. Accordingly, various researchers have always been ... -
Control of Viral and Bacterial Contamination of Lettuce by Subsurface Drip Irrigation
(ASCE, 2022/10/01)Foodborne outbreaks have been associated with the use of irrigation water contaminated with human and animal wastes. The use of subsurface drip irrigation may reduce the contamination of leafy green produce. The goal of ... -
Prediction of Bed-Load Sediment Using Newly Developed Support-Vector Machine Techniques
(ASCE, 2022/10/01)One of the significant hydrological processes affecting the sustainability of river engineering is sedimentation. Sedimentation has a major impact on reservoir and dam operations. This study conducted an experiment using ... -
Experimental Investigation of the Emptying Process and Air Cavity Dynamic in Pipelines
(ASCE, 2022/11/01)The emptying process of initially stagnant full-pipe flows in sewer systems and water transmission lines was extensively studied in the literature. The following air intrusion and depressurization wavefronts can cause ... -
An Explicit Equation for the Maximum Water Application Depth in Center Pivot Irrigation
(ASCE, 2022/11/01)A simple explicit formula was derived to determine the maximum irrigation depth (Dmax) that can be applied per irrigation without any runoff under a center pivot and/or linear move irrigation system. The analysis is built ... -
Improving Land-Surface Model Simulations in Irrigated Areas by
(ASCE, 2022/11/01)Currently, land surface models (LSMs) are limited in representing realistic water -
Optimal Sprinkler Spacing for a Mini Center Pivot System
(ASCE, 2022/11/01)This paper offers a new model for determining the optimal spacing of mini center pivot system (MCPS) nozzles for high water application uniformity. The strengths of the study included an in-depth analysis of optimum nozzle ...
