Transitional and Weir Flow in a Vented Drop Shaft with a Sharp-Edged Intake
(American Society of Civil Engineers, 2016)An experimental analysis of a vertical drop shaft with a sharp-edged horizontal intake section and a coaxial venting pipe is undertaken to obtain design criteria given the limited attention provided by literature. Three ... -
Construction Risk Management of Irrigation Dams
(American Society of Civil Engineers, 2016)The timely completion of complex dam-construction projects is a challenging proposition, both in developing and developed countries. Delays are frequent in such projects and impose costly burdens on regional and national ... -
Evaluation of the Potential Impact of Rainfall Intensity Variation due to Climate Change on Existing Drainage Infrastructure
(American Society of Civil Engineers, 2015)The potential impact of climate change on the existing drainage infrastructure has been an essential aspect of many hydrological studies. Climate change that will increase the intensity of precipitation will also increase ... -
Nonlinear Muskingum Model for Flood Routing in Irrigation Canals Using Storage Moving Average
(American Society of Civil Engineers, 2016)The Muskingum routing method involves the calculation of the storage volume in river reaches. The accurate calculation of the storage volume is difficult to achieve with the nonlinear Muskingum model (NMM). This paper ... -
Water Balance in Irrigation Reservoirs Considering Flood Control and Irrigation Efficiency Variation
(American Society of Civil Engineers, 2016)The combined effect of limited water resources and ever-growing water demand necessitates the use of more-accurate approaches for reservoir water-balance analyses. Therefore, this study aims to develop a new operational ... -

Sprinkler Irrigation Droplet Dynamics. II: Numerical Solution and Model Evaluation
(American Society of Civil Engineers, 2016)A system of equations, with strong physical basis, was derived for sprinkler irrigation droplet dynamics in the companion paper. Numerical solution of these equations and model evaluation is discussed in this paper. With ... -
Denitrification Field Study at a Wastewater Land Application Site
(American Society of Civil Engineers, 2016)A few risks restrict the sustainable development of wastewater land application including potential nitrogen contamination to groundwater. One important component is nitrogen loss caused by denitrification in a nitrogen ... -
Sprinkler Irrigation Droplet Dynamics. I: Review and Theoretical Development
(American Society of Civil Engineers, 2016)Droplet dynamics simulations are key to predicting sprinkler irrigation precipitation patterns. This paper includes derivations of equations describing droplet motion through a steady, uniform horizontal airflow (wind). ... -
Discussion of “Effect of Fertigation on Soil Salinization and Aggregate Stability” by J. M. Moreira Barradas, A. Abdelfattah, S. Matula, and F. Dolezal

New Stage-Discharge Equation for the SMBF Flume
(American Society of Civil Engineers, 2016)Flumes for indirect discharge measurements are widespread and are characterized by a particular shape of the cross section area with various degrees of convergence and subsequent divergence. The flume named Samani, Magallanez, ... -
Clogging Prediction of Permeable Pavement
(American Society of Civil Engineers, 2016)This study considers the clogging progression prediction on the permeable pavement by using artificial neural networks (ANNs). Clogging, which is caused primarily by sediment deposition, may result in performance failure ... -
Runoff Estimation Using the NRCS Slope-Adjusted Curve Number in Mountainous Watersheds
(American Society of Civil Engineers, 2016)In mountainous watersheds, rainfall generates runoff quickly because of the decreased depression storage, high downslope flow velocity, and smaller chance for rainwater infiltration. In order to obtain precise event-based ... -
Conjunctive Management of Surface and Ground Water Resources Using Conflict Resolution Approach
(American Society of Civil Engineers, 2016)Management of surface and ground water resources in drought-stricken regions with increasing water consumption poses a major challenge to water resource managers and decision makers. The situation is even graver in areas ... -
