Closure to “Levee Layouts and Design Optimization in Protection of Flood Areas” by Omid Bozorg Haddad, Parisa-Sadat Ashofteh, and Miguel A. Mariño
(American Society of Civil Engineers, 2016) -
Hydrology of Synthetic Turf Fields: Modeling Approach with Field Data
(American Society of Civil Engineers, 2016)The hydrology of synthetic turf field (STF) drainage systems is poorly understood, which complicates their design. Field data are collected and used to parameterize computer models simulating the hydrology of a synthetic ... -
Entropy-Based Approach for Rating Curve Assessment in Rough and Smooth Irrigation Ditches
(American Society of Civil Engineers, 2016)The aim of the present work is to propose an expeditive methodology derived from the one-dimensional (1D) entropy-based model to evaluate the water discharge in rough and smooth irrigation channels based on the knowledge ... -
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 ... -
Large-Scale Spatial and Temporal Variability in Evapotranspiration, Crop Water-Use Efficiency, and Evapotranspiration Water-Use Efficiency of Irrigated and Rainfed Maize and Soybean
(American Society of Civil Engineers, 2016)Quantification of long-term trends and magnitudes of actual crop evapotranspiration (ETc) and crop water productivity [CWP, also known as crop water use efficiency (CWUE)], especially in relation to interannual variation ... -
Reference (Potential) Evapotranspiration. II: Frequency Distribution in Humid, Subhumid, Arid, Semiarid, and Mediterranean-Type Climates
(American Society of Civil Engineers, 2016)While evapotranspiration (ET) has been a subject of research for decades, there is insufficient data, analyses and information on frequency (probability) values and distribution of this important variable for various ... -
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 ... -
Canal Monitoring Algorithm
(American Society of Civil Engineers, 2016)One of the main problems in the water management of irrigation canals is the control of water distribution among users’ outlets. This is because of the difficulty of measuring the removing flows correctly because they are ... -
Crop Coefficients: A Literature Review
(American Society of Civil Engineers, 2016)Recently presented climate change scenarios include increasing demand for water, due to both increase in temperature and variations in precipitation pattern. Since crop water requirements are related to climate and irrigation ... -
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 ... -
Application of the SVR-NSGAII to Hydrograph Routing in Open Channels
(American Society of Civil Engineers, 2016)Flow routing is used to simulate or predict downstream hydrographs on the basis of the features of upstream flow hydrographs. This paper combines support vector regression (SVR) and the nondominated sorting genetic algorithm ... -
Simple Relationships for the Optimal Design of Paired Drip Laterals on Uniform Slopes
(American Society of Civil Engineers, 2016)Microirrigation plants, if properly designed, allow water use efficiency to be optimized and quite high values of emission uniformity to be obtained in the field. It is known that disposing paired laterals, in which two ... -
Stage–Discharge Relationship for an Upstream Inclined Grid with Transversal Bars
(American Society of Civil Engineers, 2016)Check dams with grids upgrading upstream are often used in mountain rivers, where intense sediment transport and steep slopes occur. In some cases, sloping grids are used in the construction of debris flow breakers. In ... -
Surface Flow and Spread Calculations for the Preliminary Design of Porous Pavement Bike Lanes
(American Society of Civil Engineers, 2016)This study investigated methods for predicting and managing surface water spread and depth on porous pavement bike lanes adjacent to impervious traffic lanes. Results are presented from a theoretical and experimental study ... -
Integrated Water Resources Analysis at Basin Scale: A Case Study in Greece
(American Society of Civil Engineers, 2016)The hydrological and hydrogeological setting of a watershed, along with its spatial groundwater distribution, is very important for water resources management purposes. In addition, these factors are the bases for modeling ... -
Optimization of Gravity-Driven Hydraulic Flocculators to Treat Peat Extraction Runoff Water
(American Society of Civil Engineers, 2016)Peatland drainage and peat extraction result in runoff water rich in humus, sediments, and nutrients that requires simple purification methods to prevent pollution of surface waters. Chemical treatment of drainage water ... -
Discussion of “Effect of Fertigation on Soil Salinization and Aggregate Stability” by J. M. Moreira Barradas, A. Abdelfattah, S. Matula, and F. Dolezal
(American Society of Civil Engineers, 2016) -
Fuzzy State Real-Time Reservoir Operation Model for Irrigation with Gridded Rainfall Forecasts
(American Society of Civil Engineers, 2016)A short-term real-time operation model with fuzzy state variables is developed for irrigation of multiple crops based on earlier work on long-term steady-state policy. The features of the model that distinguish it from the ... -
Factorial Two-Stage Irrigation System Optimization Model
(American Society of Civil Engineers, 2016)This study proposes a factorial two-stage irrigation system optimization model (FTIM) for supporting agricultural irrigation water-resource management under uncertainty. The FTIM incorporates fractional factorial design, ... -
