Quick Surface Infiltration Test to Assess Maintenance Needs on Small Pervious Concrete Sites
(American Society of Civil Engineers, 2011)In this paper, a quick surface infiltration test is presented for assessment of pervious concrete (PC) maintenance needs on small sites. Tests were conducted on PC sidewalk sections at Auburn University in Auburn, Alabama. ... -
Application of Artificial Intelligence to Estimate Daily Pan Evaporation Using Available and Estimated Climatic Data in the Khozestan Province (South Western Iran)
(American Society of Civil Engineers, 2011)Estimation of evaporation, a major component of the hydrologic cycle, is required for a variety of purposes in water resources development and management. This paper investigates the abilities of genetic programming (GP) ... -
Mass Angle of Repose of Open-Graded Rock Riprap
(American Society of Civil Engineers, 2011)Mass angle of repose (that is, the angle at which a mass of sliding particles will come to rest) is a fundamental material property that is needed to design drainage channel linings composed of open-graded riprap stone, ... -
Prediction of Rainfall for Short Term Irrigation Planning and Scheduling—Case Study in Victoria, Australia
(American Society of Civil Engineers, 2011)In the short-term planning (7–14 days) and operation of complex irrigation systems, an estimate of irrigation water demand (IWD) is of a fundamental concern. To predict the IWD, a reliable estimate of the expected rainfall ... -
Evapotranspiration Adjustment Factors in Florida
(American Society of Civil Engineers, 2011)Actual evapotranspiration (ET) is commonly estimated at daily time intervals as the product of a crop coefficient and a reference-crop evapotranspiration ( -
Optimum Design of a Watershed-Based Tank System for the Semiarid and Subhumid Tropics
(American Society of Civil Engineers, 2011)Small reservoirs known as tanks are constructed in the watersheds of arid, semiarid, and subhumid regions of India to provide supplementary or protective irrigation to crops during dry spells of the monsoon season or full ... -
Application of Watershed-Based Tank System Model for Rainwater Harvesting and Irrigation in India
(American Society of Civil Engineers, 2011)The SOFTANK model optimally designs the watershed-based tank system by simulating field, tank, and groundwater balances. We applied this model to a small watershed consisting of six tanks (small reservoirs) in the semiarid ... -
Hydraulics of Center-Pivot Laterals: Complete Analysis of Friction Head Loss
(American Society of Civil Engineers, 2011)The classical expressions obtained through the mathematical theory of friction head loss along the center-pivot lateral are adequate for many existing center-pivots. Nevertheless, several important aspects are not accounted ... -
Hydraulic Modeling of a Mixed Water Level Control Hydromechanical Gate
(American Society of Civil Engineers, 2011)This article describes the hydraulic behavior of a mixed water level control hydromechanical gate present in several irrigation canals. The automatic gate is termed “mixed” because it can hold either the upstream water ... -
Root Zone Moisture Routing and Water Demand Calculations in the Context of Integrated Hydrology
(American Society of Civil Engineers, 2011)An important issue that integrated hydrologic models (IHMs) for river basins can address is the management of water resources in heavily inhabited and cultivated basins. To address this issue, these models need to simulate ... -
Effects of Various Irrigation Regimes on Soil Water Balance, Yield, and Fruit Quality of Drip-Irrigated Peach Trees
(American Society of Civil Engineers, 2011)The aim of this research was to determine the amount of irrigation water, irrigation interval, and water consumption that gave the greatest yield, to determine the effect of irrigation on fruit quality characteristics, and ... -
Recursive Design of Pressurized Branched Irrigation Networks
(American Society of Civil Engineers, 2011)This paper presents a new method to design pressurized branched irrigation networks. This method is called -
Conditional Assessment of Flow Measurement Accuracy
(American Society of Civil Engineers, 2011)A study conducted by the Utah Water Research Laboratory assessed the accuracies of a wide variety of flow measurement devices currently in service. During the study, a wide variety of flow measurement devices, including ... -
Optimal Crop Planning and Conjunctive Use of Surface Water and Groundwater Resources Using Fuzzy Dynamic Programming
(American Society of Civil Engineers, 2011)Optimal crop planning and the conjunctive use of surface water and groundwater resources are imperative for the sustainable management of water resources, especially in semiarid regions. In recent years, considerable ... -
Multiyear Performance of a Pervious Concrete Infiltration Basin BMP
(American Society of Civil Engineers, 2011)The use of infiltration storm-water best management practices (BMPs) has become a more commonly used approach as a means of reducing postdevelopment runoff volumes in many areas throughout the United States. Although studies ... -
Laboratory Simulation of Urban Runoff and Estimation of Runoff Hydrographs with Experimental Curve Numbers Implemented in USEPA SWMM
(American Society of Civil Engineers, 2011)The prognostic capabilities of a lumped hydrologic modeling approach may be complicated by routing and connectivity among infiltrative and impervious surfaces. We used artificial rainfall to generate runoff from impervious ... -
Two-Dimensional Numerical Model of Basin Irrigation Based on a Hybrid Numerical Method
(American Society of Civil Engineers, 2012)A numerical model of basin irrigation flow is a useful tool in the design and evaluation of surface irrigation systems. A two-dimensional (2D) complete hydrodynamic numerical model of basin irrigation was established by ... -
Procedures for Determining Maximum Emitter Discharge in Subsurface Drip Irrigation
(American Society of Civil Engineers, 2011)One problem associated with subsurface drip irrigation (SDI) is the reduction in discharge resulting from soil-water back-pressure at the emitter outlets. An experimental setup was made to measure emitter discharge and ... -
