Vertical Drain and Overflow Pipes: Literature Review and New Experimental Data
(American Society of Civil Engineers, 2018)This paper describes and discusses the available experimental investigations concerning vertical pipe flow in order to understand possible differences caused by different intake types and inflow conditions. Specific attention ... -
Design of Paired Laterals on Uniformly Sloping Fields
(American Society of Civil Engineers, 2018)Knowledge of the maximum length for paired drip laterals facilitates the economic optimization of microirrigation systems. The methodologies proposed to date have been based on complicated mathematical procedures that make ... -
Crop Water Use and Crop Coefficients of Maize in the Great Plains
(American Society of Civil Engineers, 2018)Maize water use was measured by water balance in a 6-year field trial in the west-central Great Plains of the United States. Seasonal water use of the 12-day maturity class variety varied from 616 to 774 mm, with an ... -
Fiber Reinforced Sandy Slopes under Groundwater Return Flow
(American Society of Civil Engineers, 2018)The instability of earthen embankments caused by subsurface flow draining out of the banks has been a major concern. In an effort to prevent embankment failures, tension resisting synthetic fibers may be an effective ... -
Experimental and CFD Analysis of Circular Labyrinth Weirs
(American Society of Civil Engineers, 2018)Labyrinth weirs present an effective solution for high discharge efficiency in space-restrictive situations. However, these weirs exhibit negative effects (vibrations, noise, and instability) when the nappe clings to the ... -
Accelerated Irrigation Canal Flow Change Routing
(American Society of Civil Engineers, 2018)In a traditional automated upstream controlled canal with a downstream buffer reservoir, the process to fill the buffer reservoir requires one step: the inflow to the canal is increased, and the flow change eventually ... -
Two Model Performance Comparisons with Multisite Observations Based on Uncertainty Methods for Modeling Hydrologic Dynamics
(American Society of Civil Engineers, 2018)The HSPF [Hydrologic Simulation Program—FORTRAN (Computer software). EPA National Exposure Research Laboratory, Athens, Georgia] and SWAT [Soil and Water Assessment Tool (Computer software). USDA Agricultural Research ... -
Permeable Channel Cross Section for Maximizing Stormwater Infiltration and Seepage Rates
(American Society of Civil Engineers, 2018)Maximization of infiltration and seepage rates is important to better control the quantity of stormwater to foster sustainable urban stormwater management. In this study, the effect of the cross-sectional flow area of a ... -
Energy Dissipation Prediction for Stepped Spillway Based on Genetic Algorithm–Support Vector Regression
(American Society of Civil Engineers, 2018)Accurately forecasting energy dissipation is critical to the hydraulic design of stepped spillways. In this study, support vector machine regression (SVR) was applied to estimate the energy dissipation of a stepped spillway. ... -
Effects of Reusing Peanut Seeds Grown in Saline Irrigation Water on Yield Attributes and Quality Traits
(American Society of Civil Engineers, 2018)The productivity of the peanut in salinity-prone areas has sharply declined and needs an immediate solution to meet the ever increasing demand of oilseed. It is hypothesized in this paper that the reuse of peanut seeds ... -
Developing a Model for Optimizing the Geometric Characteristics of Water Diversion Systems
(American Society of Civil Engineers, 2018)Determining dimensions of a dam diversion system has always been a challenge for designers because of uncertainties regarding flood characteristics and acceptable risk to the diversion system. This study presents a numerical ... -
Field-Obtained Soil Water Characteristic Curves and Hydraulic Conductivity Functions
(American Society of Civil Engineers, 2018)A test program consisting of two field-scale compacted clay liners (test pads) is conducted to evaluate field-obtained soil water characteristic curves (SWCCs) and hydraulic conductivity functions (k-functions). The test ... -
Smart Automated Furrow Irrigation of Cotton
(American Society of Civil Engineers, 2018)Although furrow irrigation is one of the dominant methods used for growing cotton in Australia as well as other parts of the world because of its inherent advantages including low capital cost, energy, and ease of operation, ... -
Assessing Stage-Discharge Relationships for Circular Overflow Structure
(American Society of Civil Engineers, 2018)Circular overflow structures are used in irrigation and drainage networks as water measuring structures. Different approaches can be found in the literature to formulate the stage-discharge relationship of the circular ... -
Choosing an Optimization Method for Water Resources Problems Based on the Features of Their Solution Spaces
(American Society of Civil Engineers, 2018)One of the main challenges for solving complex water-resources optimization is choosing an appropriate solution method. An important feature of optimization problems is the convexity and extent of their solution spaces. ... -
