Flow Interception Capacity of Inclined Grate
(American Society of Civil Engineers, 2016)Types C and D inlet grates have a large surface area to drain storm runoff collected along highway medians. As always, highway debris presents a clogging problem to these area grates. Under the assumption that debris would ... -
Farmerless Profit-Oriented Irrigation Scheduling Strategy for Solid Sets. I: Development
(American Society of Civil Engineers, 2016)Liberalization of agricultural markets is changing the irrigation focus from maximizing yields to maximizing profits. This study was conducted to develop a self-programmable irrigation scheduling strategy for solid sets ... -
Integrator Delay Zero Model for Design of Upstream Water-Level Controllers
(American Society of Civil Engineers, 2017)A variety of methods are in use for the design of controllers for adjusting canal gate positions to maintain a constant water level immediately upstream from check gates. These methods generally rely on a series of tests ... -
Crop Coefficients: A Literature Review
(American Society of Civil Engineers, 2016)Recently presented climate change scenarios include increasing demand for water, due to both increase in temperature and variations in precipitation pattern. Since crop water requirements are related to climate and irrigation ... -
Large-Scale Spatial and Temporal Variability in Evapotranspiration, Crop Water-Use Efficiency, and Evapotranspiration Water-Use Efficiency of Irrigated and Rainfed Maize and Soybean
(American Society of Civil Engineers, 2016)Quantification of long-term trends and magnitudes of actual crop evapotranspiration (ETc) and crop water productivity [CWP, also known as crop water use efficiency (CWUE)], especially in relation to interannual variation ... -
Discussion of “Levee Layouts and Design Optimization in Protection of Flood Areas” by Omid Bozorg Haddad, Parisa-Sadat Ashofteh, and Miguel A. Mariño

Selecting an Appropriate Operational Method for Main Irrigation Canals within Multicriteria Decision-Making Methods
(American Society of Civil Engineers, 2016)In this study, a systematic framework is introduced to prioritize several practical canal operation alternatives applying to modernization and rehabilitation projects. Several operation techniques, ranging from improved ... -
Entropy-Based Approach for Rating Curve Assessment in Rough and Smooth Irrigation Ditches
(American Society of Civil Engineers, 2016)The aim of the present work is to propose an expeditive methodology derived from the one-dimensional (1D) entropy-based model to evaluate the water discharge in rough and smooth irrigation channels based on the knowledge ... -
Choice of Hydrologic Variables for Probabilistic Drought Classification
(American Society of Civil Engineers, 2016)Management of irrigation practices takes on a more-prominent role under drought conditions. Watershed-scale drought characterization is performed using cumulative density function (CDF)-based probabilistic drought indices ... -
Application of the SVR-NSGAII to Hydrograph Routing in Open Channels
(American Society of Civil Engineers, 2016)Flow routing is used to simulate or predict downstream hydrographs on the basis of the features of upstream flow hydrographs. This paper combines support vector regression (SVR) and the nondominated sorting genetic algorithm ... -
Overland Flow Times of Concentration for Hillslopes of Complex Topography
(American Society of Civil Engineers, 2016)The time of concentration is an important parameter for predicting peak discharge at the basin outlet and for designing urban infrastructure facilities. In studying the hillslope response, employing hydraulic equations of ... -
Optimization Modeling for Conjunctive Use Planning of Surface Water and Groundwater for Irrigation
(American Society of Civil Engineers, 2016)The continuous increase in global population and simultaneous decrease in good-quality water resources emphasize the need of conjunctive use of groundwater and surface-water resources for irrigation. The optimal allocation ... -
Relative Evaporative Losses and Water Balance in Subsurface Drip and Center Pivot–Irrigated Soybean Fields
(American Society of Civil Engineers, 2015)This research evaluated the relative evaporative losses and water balance components in two soybean [ -
Regional-Scale Modeling of Reference Evapotranspiration: Intercomparison of Two Simplified Temperature- and Radiation-Based Approaches
(American Society of Civil Engineers, 2015)Two regionalized models for the distributed estimation of daily reference evapotranspiration, the temperature-based Hargreaves (HE) and the radiation-based Makkink (MK) equations, are applied in Southern Italy during the ... -
Reusing Perlite Substrates in Soilless Cultivation: Analysis of Particle Size, Hydraulic Properties, and Solarization Effects
(American Society of Civil Engineers, 2016)Using perlite substrates over several growing seasons is widely done in greenhouse production; its successful application depends on substrate modification and growing practices. The goal of this research was to characterize ... -
Integrated Water Resources Analysis at Basin Scale: A Case Study in Greece
(American Society of Civil Engineers, 2016)The hydrological and hydrogeological setting of a watershed, along with its spatial groundwater distribution, is very important for water resources management purposes. In addition, these factors are the bases for modeling ... -
Canal Monitoring Algorithm
(American Society of Civil Engineers, 2016)One of the main problems in the water management of irrigation canals is the control of water distribution among users’ outlets. This is because of the difficulty of measuring the removing flows correctly because they are ... -
Factorial Two-Stage Irrigation System Optimization Model
(American Society of Civil Engineers, 2016)This study proposes a factorial two-stage irrigation system optimization model (FTIM) for supporting agricultural irrigation water-resource management under uncertainty. The FTIM incorporates fractional factorial design, ... -
Effect of Irrigation and Climate Variability on Water Quality of Coastal Watersheds: Case Study in Alabama
(American Society of Civil Engineers, 2016)Agricultural activities are considered the leading cause of surface water quality degradation in the United States. While agricultural production in the state of Alabama is mainly rain-fed, irrigation is currently being ... -
