Application of Robust Optimization Approach for Agricultural Water Resource Management under Uncertainty
(American Society of Civil Engineers, 2013)Optimization models are widely used in agricultural water resources management programs. However, optimization models in most applications use data that is subject to uncertainty. Recently, robust optimization has been ... -
Application and Validation of Regression Analysis in the Prediction of Discharge in Asymmetric Compound Channels
(American Society of Civil Engineers, 2013)A series of laboratory experiments was performed to present the overbank flow in asymmetric rectangular compound channels. For this purpose, two different sets of asymmetric models with rectangular compound cross sections ... -
Potential Flow Solution for Open-Channel Flows and Weir-Crest Overflow
(American Society of Civil Engineers, 2013)Weirs used for water discharge measurement in open-channel systems normally operate under free-flow conditions, for which the specific energy reaches a minimum at the weir crest. This type of transitional open-channel flow ... -
Discussion of “Experimental Studies on Flow over Labyrinth Weir” by B. V. Khode, A. R. Tembhurkar, P. D. Porey, and R. N. Ingle
(American Society of Civil Engineers, 2013) -
Flood Control with Model Predictive Control for River Systems with Water Reservoirs
(American Society of Civil Engineers, 2013)Many control strategies can be found in the literature for controlling river systems. One of these methods is model predictive control (MPC), and it has already shown its efficiency for set-point control of reaches and ... -
Extraction of Multicrop Planning Rules in a Reservoir System: Application of Evolutionary Algorithms
(American Society of Civil Engineers, 2013)Multicropping is the practice of growing two or more crops in the same space during a single growing season. Planning rules are mathematical equations that use previous experiences of a water resource system to balance the ... -
Initial Drop Velocity in a Fixed Spray Plate Sprinkler
(American Society of Civil Engineers, 2013)Ballistic simulation has been successfully applied to impact sprinklers. However, ballistic simulation of center pivot sprinkler irrigation has been limited by the difficulty in estimating the initial drop velocity vector ... -
V-Shaped Multislit Weirs
(American Society of Civil Engineers, 2013)Weirs and notches are efficient devices for measuring flow rates. Banks of slit weirs forming multislit weirs allow both precise discharge measurements in a very large range of flow rates and permit a good flow regulation. ... -
Translating Wind-Speed Measurements over Alfalfa Having Varying Height for Use in the ASCE Standardized Reference ET Equation
(American Society of Civil Engineers, 2013)The ASCE Standardized Reference Evapotranspiration (ET) Equation expects wind speed measured at a height of 2 m over and downwind of a smooth measurement surface, such as actively growing clipped grass. Many agricultural ... -
Long-Term Hydraulic Performance of Porous Asphalt Pavements in Northern Sweden
(American Society of Civil Engineers, 2013)The effect of clogging on the long-term infiltration capacity and porosity of two 18- and 24-year-old porous asphalts was examined by using replicate double-ring infiltrometer tests and analyzing asphalt core samples. Tests ... -
Return Period Adjustment for Runoff Coefficients Based on Analysis in Undeveloped Texas Watersheds
(American Society of Civil Engineers, 2013)The rational method for peak discharge ( -
Using Numerical Modeling to Correct Flow Rates for Submerged Montana Flumes
(American Society of Civil Engineers, 2013)A Parshall flume is a common device for measuring open-channel flows. Some Parshall flumes, however, have been modified or constructed without a downstream diverging section. A Parshall flume that does not have its divergent ... -
Improved Planning Model for Canal Scheduling of Rotational Irrigation
(American Society of Civil Engineers, 2013)This paper depicts some limitations of a canal scheduling model that gives water delivery schedules for a rotational distribution system using the concept of weights based on the irrigation performance indicators. The ... -
Lysimetric Determination of <i>Coriandrum sativum</i> L. Water Requirement and Single and Dual Crop Coefficients in a Semiarid Climate
(American Society of Civil Engineers, 2013)To develop a proper irrigation management program, determination of crop water requirements and crop coefficients during growth stages is essential. In addition, water requirements and crop coefficients of most medicinal ... -
SWAT-Based Evapotranspirative Water Conservation Analysis Performed on Irrigated Croplands to Determine Potential Regional Water Savings
(American Society of Civil Engineers, 2013)Significant water savings might be realized, regionally and nationally, if an additional fraction of cultivated land were converted to a more effective form of irrigation (e.g., from furrow flooding to center pivot or drip, ...
