Discharge Characteristics of Weirs of Finite Crest Length with Upstream and Downstream Ramps
(American Society of Civil Engineers, 2013)This paper considers flow measurement in open channels with transverse weirs of finite crest length with sloping crests and upstream or downstream ramps—or both—for free flows. Using the broad-crested weir equation with a ... -
Simple ET0 Forms of Penman’s Equation without Wind and/or Humidity Data. I: Theoretical Development
(American Society of Civil Engineers, 2013)In this paper, new algebraic expressions are derived for estimating reference evapotranspiration ( -
Integrated Surface–Groundwater Model for Storm-Water Harvesting Using Basic Mass Balance Principles
(American Society of Civil Engineers, 2013)Storm-water harvesting from a pond for irrigation of adjacent lands is promoted as one way that may reduce pond discharge while supplementing valuable potable water used for irrigation. Reduction of pond discharge reduces ... -
Application of a Sampling Based on the Combined Objectives of Parameter Identification and Uncertainty Analysis of an Urban Rainfall-Runoff Model
(American Society of Civil Engineers, 2013)Urban rainfall-runoff modeling is important to analyze the health of urban water systems. The Storm Water Management Model (SWMM) developed by the U.S. Environmental Protection Agency (USEPA) is one of the most widely used ... -
Evaluation of Daily Reference Evapotranspiration Methods as Compared with the ASCE-EWRI Penman-Monteith Equation Using Limited Weather Data in Northeast Louisiana
(American Society of Civil Engineers, 2013)The ASCE-EWRI Penman-Monteith (ASCE PM) combination equation was recommended by the American Society of Civil Engineers–Environmental and Water Resources Institute as the standard equation for estimating reference ... -
Numerical Investigation of Flow in Triangular Gutters
(American Society of Civil Engineers, 2013)Focusing on triangular gutters with one vertical side, four issues pertaining to the design of street gutters are addressed: (1) the proper coefficient in Manning’s formula for uniform flow and friction loss in gutters; ... -
Straight-Line Method Generalization for Aquifer Parameter Estimations
(American Society of Civil Engineers, 2012)Aquifer parameter determination in practical hydrogeological studies exposes one of the most significant steps in groundwater resources assessment and management. Successful parameter estimation necessitates both a reliable ... -
Two-Dimensional Surface Flow and Solute Transport Model for Basin Irrigation with Conventional Fertilization
(American Society of Civil Engineers, 2013)The authors propose a two-dimensional surface flow and solute transport model of basin irrigation with conventional fertilization. Specifically, based on the mean velocities and water depth obtained from the complete ... -
Integrated Salt and Water Balance Modeling for the Management of Waterlogging and Salinization. II: Application of SAHYSMOD
(American Society of Civil Engineers, 2012)Waterlogging and soil salinization are the twin menaces of canal-irrigated areas located in arid and semi-arid regions of the world. An integrated spatial agro-hydro-salinity model, SAHYSMOD, was applied to analyze water ... -

Effects of Magnetized Water on Soil Chemical Components underneath Trickle Irrigation
(American Society of Civil Engineers, 2012)Magnetized water has been studied by many researchers. However, to date, there is no study about the effects of magnetized water on soil chemical characteristics such as cations and anions in trickle irrigation. This study ... -
Evaluating the Performance of Ordinary Kriging in Mapping Soil Salinity
(American Society of Civil Engineers, 2012)The performance of ordinary kriging (OK) is impacted by different factors that characterize the data sets being interpolated. The following factors were investigated as part of this study to evaluate the performance of OK ... -
Integrated Salt and Water Balance Modeling for the Management of Waterlogging and Salinization. I: Validation of SAHYSMOD
(American Society of Civil Engineers, 2012)Irrigated agriculture faces serious threats of waterlogging and soil salinization in the arid and semiarid regions of the world. In this paper, an integrated spatial-agro-hydro-salinity model (SAHYSMOD) was used to analyze ... -
Free-Surface Profiles, Velocity and Pressure Distributions on a Broad-Crested Weir: A Physical Study
(American Society of Civil Engineers, 2012)Basic experiments were conducted on a large-size broad-crested weir with a rounded corner. Detailed free-surface, velocity, and pressure measurements were performed for a range of flow conditions. The results showed the ... -
Agricultural Water Management under Uncertainty Using Minimax Relative Regret Analysis Method
(American Society of Civil Engineers, 2012)In this study, an inexact minimax relative regret analysis (IMRA) method is proposed for planning the agricultural water management under uncertainty. The IMRA incorporates interval-parameter programming (IPP) and minimax ... -
Forecasting Spatially Distributed Cotton Evapotranspiration by Assimilating Remotely Sensed and Ground-Based Observations
(American Society of Civil Engineers, 2012)Estimation of spatially distributed evapotranspiration (ET) with remote sensing could be especially valuable for developing water management tools in arid lands. For decision support over irrigated crops, these spatial ET ... -
Use of Turbidity Measurements to Estimate Suspended Solids and Nutrient Loads from Peatland Forestry Drainage
