Assessment of Airborne Transport of Potential Contaminants in a Wind Tunnel
(ASCE, 2020)The reuse of treated wastewater (TWW) for sprinkler irrigation could potentially diffuse pathogen-containing droplets off the application area. Wind and other unfavorable climatic factors enhance irrigation drift and ... -
Effects of Urea Fertigation on Emitter Clogging in Drip Irrigation System with Muddy Water
(American Society of Civil Engineers, 2019)In this study, 10 test cycles of fertigation with urea using muddy water were performed to examine the anticlogging performance of inline nonpressure-compensating emitters. The potential causes of emitter blockage were ... -
Optimal Configuration of an Underdrain Delivery System for a Stormwater Infiltration Trench
(American Society of Civil Engineers, 2019)Performance of a green infrastructure (GI) tree trench comprising planters, an underground rock infiltration bed, inlet structures collecting runoff, and a perforated underdrain pipe delivering water from the inlet structure ... -
Modeling Approaches for Determining Appropriate Depth of Subsurface Drip Irrigation Tubing in Alfalfa
(American Society of Civil Engineers, 2019)Alfalfa provides high-energy feed for dairy cows and other livestock. This crop is also known for its high water-use efficiency. Subsurface drip irrigation (SDI) is an ideal method for meeting crops’ water demands. A major ... -
Three-Dimensional Numerical Study of Stacked Drop Manholes
(American Society of Civil Engineers, 2019)Drop manhole structures are used in steep, sloped, urban areas to achieve an acceptable flow velocity inside the gravity network by reducing the slope in sewer pipes and dissipating energy. The energy dissipation is governed ... -
Temporal-Spatial Distribution Characteristics and Influencing Factors of Regional Agricultural Water Requirement Indicators
(American Society of Civil Engineers, 2019)The temporal-spatial distribution of agricultural water requirements constitutes an important basis for the optimal allocation of regional irrigation water resources. The primary crops (rice, maize, and soybeans) of 12 ... -
Transport Modeling in Sprinkler Irrigation
(American Society of Civil Engineers, 2019)Treated wastewater (TWW) reuse in crop or landscape irrigation is beneficial for water resource preservation, both quantitatively and qualitatively. However, TWW reuse based on sprinkler irrigation remains limited. This ... -
Using Rainfall Analysis to Manage Freeboard and Increase Rainfall Capture for Multiple-Inlet Rice Irrigation in the Lower Mississippi River Valley
(American Society of Civil Engineers, 2019)Research was conducted to help rice (Oryza sativa L.) farmers increase rainfall capture to offset groundwater use in the Lower Mississippi River Valley (LMRV). The LMRV is where a majority of US rice is produced and irrigated ... -
Determining Reference Evapotranspiration in Greenhouses from External Climate
(American Society of Civil Engineers, 2019)Estimations of Penman-Monteith reference evapotranspiration (EToPM) in greenhouses can benefit the operation of these intensive agricultural production systems. Meteorological variables required to calculate EToPM within ... -
MARS for Prediction of Shear Force and Discharge in Two-Stage Meandering Channel
(American Society of Civil Engineers, 2019)Accurate prediction of shear stress distribution along the boundary in an open channel is the key to the solution of numerous critical engineering problems. This paper investigated the distribution of boundary shear force ... -
Prediction of Flow-Regime Transition over a Stepped Channel
(American Society of Civil Engineers, 2019)For the hydraulic design of a stepped channel, it is crucial to estimate the limit of flow regimes. Step flow in the quasi-uniform region of a stepped channel is analyzed theoretically in this paper. The present work adopts ... -
Multiobjective Irrigation Model: Alqueva River Basin Application
(American Society of Civil Engineers, 2019)This paper aims to solve an optimal irrigation water resources allocation problem applied to Alqueva River Basin irrigation system in Portugal. A multiobjective model was developed for this purpose in which the economic, ... -
Alternative Water Transfer Methods: Review of Colorado Experiences
(American Society of Civil Engineers, 2019)Transfers of the right to use water can provide flexibility in regions where cities and farms compete for supplies. For example, the state of Colorado’s prior appropriation water law allows purchase and transfer of water ... -
Improved Water and Economic Sustainability with Low-Input Compact Bed Plasticulture and Precision Irrigation
(American Society of Civil Engineers, 2019)Raised-bed plasticulture is used globally to produce fresh market vegetables, fruits, and other crops. A novel compact bed geometry, designed to improve the system efficiency of plasticulture, was evaluated for its ability ... -
