Intercomparison Testing and Evaluation of Sprinklers within the INITL
(American Society of Civil Engineers, 2016)The International Network of Irrigation Testing Laboratories (INITL) undertook a sprinkler intercomparison testing exercise to generate data for an objective comparison of the performances of the different facilities and ... -
Estimation of Reference Evapotranspiration Using Neural Networks and Cuckoo Search Algorithm
(American Society of Civil Engineers, 2016)The ability to optimize an artificial neural network (ANN) and adaptive neuro-fuzzy inference system (ANFIS) in reference evapotranspiration (ET0) estimation using the cuckoo search algorithm (CSA) is studied in this paper. ... -
Numerical Modeling of Submerged Hydraulic Jump from a Sluice Gate
(American Society of Civil Engineers, 2016)The velocity field and surface profile of an open channel flow with a submerged hydraulic jump from a vertical sluice gate are investigated for two different flow cases. The governing equations are numerically solved using ... -
Rating Rectangular Farm Delivery Meter Gates for Flow Measurement
(American Society of Civil Engineers, 2016)Traditional meter gates for farm delivery flow measurement from an open channel conveyance have traditionally incorporated round canal gates (Armco type) for control. In recent years, some irrigation water agencies ... -
Development of a Flow and Transport Model for Drainage Network Conception in Northern Tunisia
(American Society of Civil Engineers, 2016)In Tunisia, the salinization phenomenon in irrigated areas is frequently worsened by poor drainage. In this context, the irrigated area of Cebala Borj-Touil was studied in order to conceive an efficient drainage network. ... -
Estimation of Furrow Irrigation Sediment Loss Using an Artificial Neural Network
(American Society of Civil Engineers, 2016)The area irrigated by furrow irrigation in the United States has been steadily decreasing but still represents about 20% of the total irrigated area in the United States. Furrow irrigation sediment loss is a major water ... -
Effect of Inflow Froude Number on Flow Pattern in Channel-Expansive Transitions
(American Society of Civil Engineers, 2016)Channel expansions are common in both natural and artificial open channels. With increasing cross-sectional dimensions in an expansion, flow decelerates. Because of the complexity of flow patterns, physical models alone ... -
Minimum Specific Energy and Transcritical Flow in Unsteady Open-Channel Flow
(American Society of Civil Engineers, 2016)The study and computation of free surface flows is of paramount importance in hydraulic and irrigation engineering. These flows are computed using mass and momentum conservation equations, their solutions exhibiting special ... -
Methodology for the Estimation of Wetting Front Length and Potential Recharge under Variable Depth of Ponding
(American Society of Civil Engineers, 2016)A methodology for determining the length of advancement of wetting front and potential groundwater recharge under variable depth of ponding is presented. The methodology provides no restrictions to infiltration time period, ... -
Sprinkler Irrigation Pressure and Spacing Effect for Cold Protection of Strawberries
(American Society of Civil Engineers, 2016)Irrigation for cold protection in strawberries has been used for many years to protect plants from cold damage; however, large volumes of high-quality water are needed for this purpose. Based on computer modeling for citrus, ... -
Accuracy of Round Meter Gates for On-Farm Deliveries
(American Society of Civil Engineers, 2016)Recent California legislation requires irrigation water agencies larger than 25,000 acres to measure volumetric water deliveries within specified levels of relative uncertainty. Although the meter gate is one of the most ... -
