Random Scenarios Generation with Minimum Energy Consumption Model for Sectoring Optimization in Pressurized Irrigation Networks Using a Simulated Annealing Approach
(American Society of Civil Engineers, 2012)A pressurized irrigation network may operate in two ways, namely, on demand and organized under operating sectors. In the first case, the user decides when to irrigate, and the pumping station has to meet the discharge and ... -
Discharge Efficiency of Reservoir-Application-Specific Labyrinth Weirs
(American Society of Civil Engineers, 2012)Published labyrinth weir design methods, which have primarily been developed on the basis of labyrinth weir test data from laboratory flumes, are specific to in-channel labyrinth weir applications in which the approach ... -
Hydraulic Performance of Asymmetric Labyrinth Side Weirs Located on a Straight Channel
(American Society of Civil Engineers, 2012)This paper details a new design for labyrinth side weirs, which has been tested and analyzed. The proposed geometry for this labyrinth side weir differs from a triangular labyrinth side weir, in that it is asymmetric in ... -
Comparison of SWAP and FAO Agro-Hydrological Models to Schedule Irrigation of Wine Grapes
(American Society of Civil Engineers, 2012)This paper compares two agro-hydrological models that are used to schedule irrigation of a typical Mediterranean crop. In particular, a comparison between the Food and Agriculture Organization (FAO) model, which uses a ... -
Analytical Solution for Drainflows from Bilevel Multiple-Drain Subsurface Drainage Systems
(American Society of Civil Engineers, 2012)Waterlogging and soil salinisation is widespread in the semiarid, irrigated areas of the world. Subsurface drainage is a useful tool in reducing these effects on crops; however, there has been negative downstream effects ... -
Semiquantitative Analysis of Water Appropriations and Allocations in the Upper Rio Grande Basin, Colorado
(American Society of Civil Engineers, 2012)A semiquantitative analysis was used to assess the impacts of water rights appropriations and allocations in the Upper Rio Grande (URG) Basin, in Colorado. The study also explores the causes and effects of the changes on ... -
Real-Time Model for Optimal Water Allocation in Irrigation Systems during Droughts
(American Society of Civil Engineers, 2012)The agricultural sector is the main victim of drought and efficient water planning, and management is the best strategy to reduce drought pressures on this sector. One operational approach is the application of real-time ... -
Water Budget Calculator Created for Residential Urban Landscapes in Albuquerque, New Mexico
(American Society of Civil Engineers, 2012)The current methods used to calculate urban landscape water budgets are limited because they lack site specificity. The objective of this study was to create a landscape water budget web interface based on ground-proofed ... -
Discussion of “Recursive Design of Pressurized Branched Irrigation Networks” by César González-Cebollada, Bibiana Macarulla, and David Sallán

Hydraulic Characteristics of a Drop Square Manhole with a Downstream Control Gate
(American Society of Civil Engineers, 2012)Manhole drops in drainage systems are often designed for providing energy dissipation, for controlling high velocities and for minimizing sewers structural damage. The flow is characterized by excessive air-entrainment and ... -
Testing of Microhydropower Generation from a Sprinkler Irrigation System
(American Society of Civil Engineers, 2012)Sprinkler irrigation is one of the advanced water-saving irrigation technologies, which has a significant effect for the development of agriculture. Sprinklers are designed to rotate in a circle. In practice, sprinklers ... -
Irrigation Patterns and Scheduling of a Telecontrolled Irrigation District in Northeastern Spain
(American Society of Civil Engineers, 2012)Over the last 10 years, telecontrol systems have been incorporated into the majority of modern collective pressurized irrigation networks in Spain. This type of infrastructure provides many opportunities for irrigation ... -
Darcian Seepage through a Parallelogrammic Ramp: Toth’s Model Revisited
(American Society of Civil Engineers, 2012)Fully saturated, 2-D steady seepage in a homogeneous, isotropic, parallelogrammic ramp is studied using the methods of complex analysis (a conformal mapping and integral representation of mixed boundary-value problem). A ... -
Characteristics of Flow over Rectangular Sharp-Crested Side Weirs
(American Society of Civil Engineers, 2012)In this study, water flow over rectangular sharp-crested side weirs of various heights and widths was investigated. The distribution of the three-dimensional velocity over the crest and in the vicinity of the side weir was ... -
Montana Flume Flow Corrections under Submerged Flow
(American Society of Civil Engineers, 2012)A Montana flume is a Parshall flume without a diverging downstream section and is used to measure open channel flow. Under free-flow conditions, the Parshall flume and the Montana flume have the same calibration characteristics, ... -

Optimizing Irrigation Water Allocation and Multicrop Planning Using Discrete PSO Algorithm
(American Society of Civil Engineers, 2012)This study presents a linear and a mixed-integer linear (MIL) model for optimizing an irrigation water allocation and a multicrop planning problem. The main objective was to maximize net benefit for all cultivated crops ... -
Pareto-Based Methodology for the Calibration and Uncertainty Analysis of Gated Culvert Flows
(American Society of Civil Engineers, 2012)An improved flow rating equation for full-barrel flows through a gated culvert was developed by calibrating a flow model to measured flow data with the Pareto-based approach to inverse parameter estimation. The computed ... -
Cost Comparison of Conventional Gray Combined Sewer Overflow Control Infrastructure versus a Green/Gray Combination
(American Society of Civil Engineers, 2012)This paper outlines a life-cycle cost analysis comparing a green (rain gardens) and gray (tunnels) infrastructure combination to a gray-only option to control combined sewer overflow in the Turkey Creek Combined Sewer ... -
Effect of Topographic Data Accuracy on Water Storage Environmental Service and Associated Hydrological Attributes in South Florida
(American Society of Civil Engineers, 2012)The effects of digital elevation model (DEM) accuracy on terrain attributes and water storage were evaluated by comparing a standard 10-m U.S. Geological Survey DEM and a 10-m DEM derived from Light Detection and Ranging ...
