Developing Corn Regional Crop Coefficients Using a Satellite-Based Energy Balance Model (ReSET-Raster) in the South Platte River Basin of Colorado
(American Society of Civil Engineers, 2013)Improved irrigation management depends on accurate irrigation scheduling that should be based on estimates of daily crop water requirements. Traditional methods for estimating daily crop water requirements use a generic ... -
Analytical and Experimental Investigation of a Side-Weir Detention Basin in Flood-Level Reduction in the Main Channel
(American Society of Civil Engineers, 2013)To design the off-stream detention basin by the sides of rivers or channels, flood-level reduction in main channels should be evaluated under unsteady flow. Flow discharge diverted to the side weir from the main stream can ... -
Evaluation of Spatial and Temporal Root Water Uptake Patterns of a Flood-Irrigated Pecan Tree Using the HYDRUS (2D/3D) Model
(American Society of Civil Engineers, 2013)Quantitative information about the spatial and temporal patterns of compensatory root water uptake (RWU) in flood-irrigated pecan orchard is limited. We evaluated spatio-temporal compensated and uncompensated RWU patterns ... -
Modeling Subsurface Heterogeneity of Irrigated and Drained Fields. I: Model Development and Testing
(American Society of Civil Engineers, 2013)Efficient management of irrigation/drainage systems relies to a large extent on the ability to predict a priori the response of the system to a proposed management plan. However, such numerical prediction of system response ... -

Experimental Study of the Stage-Discharge Relationship for an Upstream Inclined Grid with Longitudinal Bars
(American Society of Civil Engineers, 2013)In this paper, the outflow process of an upstream inclined grid with longitudinal bars is studied by using the dimensional analysis and the incomplete self-similarity theory. Next, the theoretical analysis shows that a ... -
Discussion of “Hydraulic and Statistical Analyses of Design Emission Uniformity of Trickle Irrigation Systems” by Jafar Safaa Noori and Hayder A. Al Thamiry
(American Society of Civil Engineers, 2013) -
Novel Approach for Side Weirs in Supercritical Flow
(American Society of Civil Engineers, 2013)Side weirs are hydraulic structures widely used in practice and extensively studied in the technical literature. The flow along a side weir is a classic example of spatially varied flow, the study of which is generally ... -
Efficient Management of Dry Spells with Supplemental Irrigation for Maximum Productivity of Groundnut in Arid Alfisols of South India
(American Society of Civil Engineers, 2013)Field experiments were conducted during kharif 2009 and 2010 at the Agricultural Research Station, Anantapur, located in the scarce rainfall zone of Andhra Pradesh in south India to assess the effect of dry spells or ... -
Defining Spatial Heterogeneity of Hillslope Infiltration Characteristics Using Geostatistics, Error Modeling, and Autocorrelation Analysis
(American Society of Civil Engineers, 2013)Procedures that can characterize spatial correlation and interpolate values at unknown locations can be valuable in capturing spatial trends, may increase sampling accuracy, and reduce error. This study sought to compare ... -
Application of an In-Line Storage Strategy to Improve the Operational Performance of Main Irrigation Canals Using Model Predictive Control
(American Society of Civil Engineers, 2013)Storing water in main irrigation canal reaches could be an influential strategy to improve the existing operational activities in the irrigation canals. However, the control of such a canal system will become much more ... -
Supercritical Flow Measurement Using a Large Parshall Flume
(American Society of Civil Engineers, 2013)A full-prototype physical model was laboratory tested to determine a rating equation applicable to large Parshall flumes with supercritical flow. The experimental program was composed of a 1.5-m (5-ft.) Parshall flume ... -
Novel Use of Time Domain Reflectometry in Infiltration-Based Low Impact Development Practices
(American Society of Civil Engineers, 2013)Low impact development (LID) practices intercept storm-water runoff and infiltrate it through a range of media types and underlying soils. Hydrologic performance is typically evaluated by comparing inlet and underdrain ... -
