Routing Demand Changes to Users on the WM Lateral Canal with SacMan
(American Society of Civil Engineers, 2010)Most canals have either long travel times or insufficient in-canal storage to operate on demand. Thus most flow changes must be routed through the canal. Volume compensation has been proposed as a method for easily applying ... -
Effect of Storm-Water Wetlands and Wet Ponds on Runoff Temperature in Trout Sensitive Waters
(American Society of Civil Engineers, 2010)With increasing development in areas of trout sensitive waters, the effect of urban storm-water runoff temperature on the aquatic ecosystem has become a concern. A study was conducted in western North Carolina, along the ... -
Discussion of “Modifications to SCS-CN Method for Long-Term Hydrologic Simulation” by K. Geetha, S. K. Mishra, T. I. Eldho, A. K. Rastogi, and R. P. Pandey
(American Society of Civil Engineers, 2010) -
Analysis and Synthesis of Transmission Loss Hydrographs
(American Society of Civil Engineers, 2010)Accounting for transmission losses properly is critical in hydrologic analyses in arid and semiarid climates. The objective of this research was to develop a model that could account for the spatial and temporal variations ... -
Optimization of Underground Water Pumping
(American Society of Civil Engineers, 2010)Nowadays, it is necessary to develop methodologies, tools, and actions that try to optimize the use of the energy resources. One of the main problems found was the improper dimensioning of the pumping for undergroundwater ... -
Estimation of Unsaturated Hydraulic Parameters from Infiltration and Internal Drainage Experiments
(American Society of Civil Engineers, 2010)Inverse problem of determining unsaturated soil hydraulic properties from transient infiltration and internal drainage events are analyzed. Hydraulic properties are assumed to be described by van Genuchten’s relationships. ... -
Energy and Momentum Velocity Coefficients for Calibrating Submerged Sluice Gates in Irrigation Canals
(American Society of Civil Engineers, 2010)There is renewed interest in developing calibration methods for gates operating in submerged conditions in irrigation canals. In the present study, a new method based on a generalization of the standard energy-momentum ... -

Water Table Fluctuation in the Presence of a Time-Varying Exponential Recharge and Depth-Dependent ET in a Two-Dimensional Aquifer System with an Inclined Base
(American Society of Civil Engineers, 2010)An analytical solution is presented for water table fluctuation between ditch drains in presence of exponential recharge and depth-dependent evapotranspiration (ET) from groundwater table in a two-dimensional gently sloping ... -
Discharge Coefficient for a Water Flow through a Bottom Orifice of a Conical Hopper
(American Society of Civil Engineers, 2010)Discharge coefficients for water flow through a vertical, circular orifice at the bottom of a conical hopper were experimentally studied in the present paper. The conical hopper consists of a cylindrical hopper of inside ... -

Supervised Gain-Scheduling Multimodel versus Linear Parameter Varying Internal Model Control of Open-Channel Systems for Large Operating Conditions
(American Society of Civil Engineers, 2010)In this paper, two internal model control (IMC) controllers using gain-scheduling techniques are proposed and compared for open-channel systems that allow to deal with large operating conditions. In particular, in one side, ... -
Relative Comparison of the Local Recalibration of the Temperature-Based Evapotranspiration Equation for the Korea Peninsula
(American Society of Civil Engineers, 2010)It is well known that local calibration is subject to improving the performance of the temperature-based equation because that calibration includes the influence of the local climate characteristics. This paper evaluates ... -
Design of a Single-Pool Downstream Controller Using Quantitative Feedback Control Theory
(American Society of Civil Engineers, 2010)A downstream controller is designed for an irrigation canal reach using a design technique called quantitative feedback control theory (QFT). The performance of this controller is compared to a proportional, integral, ... -
