Using a Surface Energy Balance Model to Calculate Spatially Distributed Actual Evapotranspiration
(American Society of Civil Engineers, 2011)Remote sensing algorithms are currently being used to estimate regional surface energy fluxes [e.g., latent heat flux or evapotranspiration (ET)]. Many of these surface energy balance models use information derived from ... -
Hydraulics of Circular Drop Manholes
(American Society of Civil Engineers, 2011)Circular drop manholes are widely employed in steep urban drainage systems. Drop manholes may lead to poor hydraulic conditions if their energy dissipation is inadequate. The dominant hydraulic features of drop manholes ... -
Evaluating the Impact of Daily Net Radiation Models on Grass and Alfalfa-Reference Evapotranspiration Using the Penman-Monteith Equation in a Subhumid and Semiarid Climate
(American Society of Civil Engineers, 2011)Net radiation -
SDI Dripline Spacing Effect on Corn and Soybean Yield in a Piedmont Clay Soil
(American Society of Civil Engineers, 2011)A subsurface drip irrigation (SDI) system was installed in the Piedmont of North Carolina in a clay soil in the fall of 2001 to test the effect of dripline spacing on corn and soybean yield. The system was zoned into three ... -
OCCASION: New Planning Tool for Optimal Climate Change Adaption Strategies in Irrigation
(American Society of Civil Engineers, 2010)To sustain productive irrigated agriculture with limited water resources requires a high water use efficiency. This can be achieved by the precise scheduling of deficit irrigation systems taking into account the crops’ ... -
Canal Structure Automation Rules Using an Accuracy-Based Learning Classifier System, a Genetic Algorithm, and a Hydraulic Simulation Model. II: Results
(American Society of Civil Engineers, 2011)An accuracy-based learning classifier system (XCS), as described in a companion paper (Part I: Design), was developed and evaluated to produce operational rules for canal gate structures. The XCS was applied together with ... -
Canal Structure Automation Rules Using an Accuracy-Based Learning Classifier System, a Genetic Algorithm, and a Hydraulic Simulation Model. I: Design
(American Society of Civil Engineers, 2011)Using state-of-the-art computational techniques, a genetic algorithm (GA) and an accuracy-based learning classifier system (XCS) were shown to produce optimal operational solutions for gate structures in irrigation canals. ... -

Experimental Determination of the Hydraulic Properties of Low-Pressure, Lay-Flat Drip Irrigation Systems
(American Society of Civil Engineers, 2011)The hydraulics of IDEal low-pressure drip irrigation system components were analyzed under controlled laboratory conditions. The hydraulic loss coefficient for the lateral-submain connector valves was determined based on ... -
River Hydrograph Retransmission Functions of Irrigated Valley Surface Water–Groundwater Interactions
(American Society of Civil Engineers, 2010)Storage and release functions of western U.S. traditional river valley irrigation systems may counteract early and rapid spring river runoff associated with climate variation. Along the Rio Grande in northern New Mexico, ... -

Fines Accumulation and Distribution in a Storm-Water Rain Garden Nine Years Postconstruction
(American Society of Civil Engineers, 2010)Storm water control measures (SCMs), also known as best management practices (BMPs), such as rain gardens, are designed to infiltrate storm-water runoff and reduce pollutant transport to surface waters. The life span of ... -
High-Resolution Method for Modeling Hydraulic Regime Changes at Canal Gate Structures
(American Society of Civil Engineers, 2010)A method for modeling flow regime changes at gate structures in canal reaches is presented. The methodology consists of using an approximate Riemann solver at the internal computational nodes, along with the simultaneous ... -

Real-Time Implementation of Model Predictive Control on Maricopa-Stanfield Irrigation and Drainage District’s WM Canal
(American Society of Civil Engineers, 2010)Water resources are limited in many agricultural areas. One method to improve the effective use of water is to improve delivery service from irrigation canals. This can be done by applying automatic control methods that ... -
Lattice Boltzmann Model for the Simulation of Flows in Open Channels with Application to Flows in a Submerged Sluice Gate
(American Society of Civil Engineers, 2010)Numerical simulations of free-surface flows are important to provide a prediction tool for the optimal management of irrigation canals. Here, we consider an alternative to solving the shallow-water equations. We propose a ... -
