Predicting Incoming Solar Radiation and Its Application to Radiation-Based Equation for Estimating Reference Evapotranspiration
(American Society of Civil Engineers, 2009)This paper presents an inverse square weighted interpolation for predicting the incoming solar radiation -
Evaluation of a Nonlinear Root-Water Uptake Model
(American Society of Civil Engineers, 2009)Soil-water movement due to root-water uptake, is a key process for plant growth and transport of water in the soil plant system. There are different root-water uptake models to determine the extraction rate of soil moisture ... -
Drawdown due to Pumping a Partially Penetrating Large-Diameter Well Using MODFLOW
(American Society of Civil Engineers, 2009)The approach by the author for modeling the large-diameter wells using MODFLOW is extended to the partially penetrating large-diameter wells. The temporal variation of drawdown due to a steady pumping is presented in the ... -
Sustainable Root Zone Salinity and Shallow Water Table in the Context of Land Retirement
(American Society of Civil Engineers, 2010)This study uses five years of field data from the Land Retirement Demonstration Project located in western Fresno County of California to develop a comprehensive theoretical and numerical modeling framework to evaluate the ... -
Aquifer Parameter Estimation for a Constant-Flux Test Performed in a Radial Two-Zone Aquifer
(American Society of Civil Engineers, 2009)A patchy aquifer or an aquifer with a finite thickness skin can be considered as a radial two-zone aquifer system, which can be characterized by five parameters, i.e., the thickness of the first zone and four aquifer ... -

Soil Moisture Flow Modeling with Water Uptake by Plants (Wheat) under Varying Soil and Moisture Conditions
(American Society of Civil Engineers, 2009)A variably saturated soil moisture flow model is developed for planted soils with depth varying properties by incorporating a nonuniform macroscopic root water uptake function. The model includes spatial and temporal ... -
Generalized Analytical Solutions for Groundwater Head in a Horizontal Aquifer in the Presence of Subsurface Drains
(American Society of Civil Engineers, 2009)Generalized analytical solutions for groundwater head in horizontal aquifers in the presence of parallel subsurface drains are obtained considering a transient rate of recharge as a power series (polynomial) function and ... -
Influence of the Spatial Configuration of the Irrigated Zone on the Irrigation Network Layout Design
(American Society of Civil Engineers, 2009)The present work aims at taking us closer to the study of the influence of the spatial configuration of the irrigated zone on the unit cost (€/ha) of a layout irrigation network design. The layout analyzed in this paper ... -
Evaluation of the Water Delivery Performance of the Menemen Left Bank Irrigation System Using Variables Measured On-Site
(American Society of Civil Engineers, 2009)This study determines the water delivery performance at secondary and tertiary canal level of the Menemen Left Bank Irrigation system, an open canal irrigation system located in Turkey, for the irrigation seasons of the ... -
Estimation of Crop Coefficients Using Satellite Remote Sensing
(American Society of Civil Engineers, 2009)Crop coefficient -

Water Distribution in Laterals and Units of Subsurface Drip Irrigation. I: Simulation
(American Society of Civil Engineers, 2009)A complete methodology to predict water distribution in laterals and units of subsurface drip irrigation (SDI) is proposed. Two computer programs have been developed for the hydraulic characterization of SDI; one for ... -
Errors in Surface Irrigation Evaluation from Incorrect Model Assumptions
(American Society of Civil Engineers, 2009)Some two-dozen methods have been proposed in the literature for estimating an infiltration function from field measurements. These methods vary in their data requirements and analytical rigor, however most assume some ... -
Structured Application of the Two-Point Method for the Estimation of Infiltration Parameters in Surface Irrigation
(American Society of Civil Engineers, 2009)The two-point method is one of the best known procedures for estimating empirical infiltration parameters from surface irrigation evaluation data and mass balance, mainly because of its limited data requirements and ... -
New Methodology for the Risk Analysis and Economic Impact Assessment of Agricultural Droughts
(American Society of Civil Engineers, 2009)The paper proposes a new methodology that studies agricultural drought not only in terms of deficit soil water content, its frequency and severity, as in the traditional approach, but also in terms of net benefit. For this ... -

Identifying Two-Dimensional Characteristics of Surface Water Hydraulics in an Irrigated Paddy Field
(American Society of Civil Engineers, 2009)To efficiently manage the water supply for paddy rice and to reduce the inundation damage from floods, it is necessary to enhance our understanding of the characteristics of the surface water hydraulics in an irrigated ... -
Retrofitting Detention Basin with Water Quality Control Pool
(American Society of Civil Engineers, 2009)Many detention basins built before 1990 are not equipped with storm-water quality control device. With the latest developments in low impact development for storm-water management, these existing detention basins need ...
