Hydrologic and Water Quality Aspects of Using a Compost/Mulch Blend for Erosion Control
(American Society of Civil Engineers, 2010)Construction projects often expose large amounts of soil to erosive forces of wind and rain. These areas must be stabilized and vegetated before a Notice of Termination can be submitted to regulators. The objectives of ... -
Estimating Reference Evapotranspiration with Minimum Data in Florida
(American Society of Civil Engineers, 2010)Reference evapotranspiration estimation methods that require minimal data are necessary when climatic data sets are incomplete, inaccurate, or unavailable. This study was conducted to evaluate temperature-based reference ... -
Flow over Gabion Weirs
(American Society of Civil Engineers, 2010)A conventional weir typically consists of an impermeable body constructed of concrete, since its primary functions are to heading up water and efficiently regulate flow. However, an impermeable body prevents the longitudinal ... -
Overtopping Probability Constrained Optimal Design of Composite Channels Using Swarm Intelligence Technique
(American Society of Civil Engineers, 2010)In this paper swarm intelligence based methodology is proposed for optimal and reliable design of irrigation channels. The input parameters involved in channel design are prone to uncertainty and the solution of deterministic ... -
Evaluation of a Dielectric Sensor for Measurement of Soil-Water Electrical Conductivity
(American Society of Civil Engineers, 2010)The salinity status of soil can be obtained through the measurement of the pore-water electrical conductivity -
Knowledge-Based Model for Supplementary Irrigation Assessment in Agricultural Watersheds
(American Society of Civil Engineers, 2010)In this paper a knowledge-based model for supplementary irrigation assessment in rainfed agricultural watersheds is presented. The supplementary irrigation assessment problem is divided into different components and is ... -
Discussion of “Turbulence Modeling of Flows over Circular Spillways” by Rahim Tadayon and Amruthur S. Ramamurthy
(American Society of Civil Engineers, 2010) -
Comparison of Ordinary Kriging, Regression Kriging, and Cokriging Techniques to Estimate Soil Salinity Using LANDSAT Images
(American Society of Civil Engineers, 2010)The objectives of this study are: (1) to evaluate the LANDSAT best band combinations to estimate soil salinity with different crop types; (2) to compare ordinary kriging, regression kriging, and cokriging techniques to ... -
Discussion of “Development of an Empirical Lag Time Equation” by Norman D. Folmar and Arthur C. Miller
(American Society of Civil Engineers, 2010) -
Discussion of “Evolutionary Algorithms for the Determination of Critical Depths in Conduits” by A. Kanani, M. Bakhtiari, S. M. Borghei, and D.-S. Jeng

Modeling Evapotranspiration of Two Land Covers Using Integrated Hydrologic Model
(American Society of Civil Engineers, 2010)Modeling evapotranspiration (ET) distribution in shallow water table environments is of great importance for understanding and reproducing other hydrologic fluxes such as runoff and recharge. Unfortunately, ET distribution ... -
Irrigation Distribution Networks’ Vulnerability to Climate Change
(American Society of Civil Engineers, 2010)Climate change will lead to changed demands on existing irrigation systems. This paper presents a methodology for investigating the performance of irrigation networks under climate change, and applies this to an irrigation ... -
Evaluating Watershed Experiments through Recursive Residual Analysis
(American Society of Civil Engineers, 2010)The question of watershed response to changes in land use and land cover has received a great deal of attention in the hydrologic literature. One of the primary tools for quantifying such changes has been the paired watershed ... -
Canal Seepage Reduction by Soil Compaction
(American Society of Civil Engineers, 2010)Simple in situ vibratory soil compaction of earth lined canals was tested to determine the impact on seepage losses. Commercial equipment was used for vibratory compaction of long sections of five irrigation district earthen ... -
Correspondence between the Campbell and van Genuchten Soil-Water-Retention Models
(American Society of Civil Engineers, 2010)Two methods are presented that allow converting the van Genuchten (VG) soil-water-retention (SWR) model parameters to equivalent parameters of the Campbell (C) model. The first method builds on an available solution to ... -
Runoff Characteristics for Construction Site Erosion Control Practices
(American Society of Civil Engineers, 2010)Controlling soil erosion during and after construction is a major concern due to the impacts of sediment on stream water quality, and many studies have focused on the effectiveness of erosion control best management practices ... -
Impact of Irrigation Management Transfer on Land and Water Productivity and Water Supply in the Gediz Basin, Turkey
(American Society of Civil Engineers, 2010)In the 1990s, Turkey started a fast transfer program in which a large proportion of government-managed irrigation systems were put into the hands of Water Users’ Associations (WUAs) in a very short space of time. One of ... -
