Physically Based Model for Simulating Flow in Furrow Irrigation. I: Model Development
(American Society of Civil Engineers, 2009)Researchers developed several mathematical models for simulating furrow irrigation using the Saint-Venant equations. Most of these irrigation models use numerical techniques to solve these equations, which in general, ... -
Toward Physically Based Estimation of Surface Irrigation Infiltration
(American Society of Civil Engineers, 2009)Irrigation practitioners use empirical infiltration equations. Theoretical infiltration equations are currently not capable of capturing surface irrigation infiltration behavior, particularly during initial wetting. For a ... -
Estimation of Soil and Crop Hydraulic Properties
(American Society of Civil Engineers, 2009)Some two dozen methods for estimating infiltration and roughness parameters from field measurements of test irrigations are reviewed in this paper. They differ in their assumptions, ease of analysis, quantity of field data ... -
Physically Based Model for Simulating Flow in Furrow Irrigation. II: Model Evaluation
(American Society of Civil Engineers, 2009)In this study, the physically based furrow irrigation model presented in Part 1 was evaluated using the experimental data collected from a field plot consisting of three 40-m-long free-drained furrows of parabolic shape ... -
Discussion of “Method of Solution of Nonuniform Flow with the Presence of Rectangular Side Weir” by Maurizio Venutelli
(American Society of Civil Engineers, 2009) -
Bernoulli Theorem, Minimum Specific Energy, and Water Wave Celerity in Open-Channel Flow
(American Society of Civil Engineers, 2009)One basic principle of fluid mechanics used to resolve practical problems in hydraulic engineering is the Bernoulli theorem along a streamline, deduced from the work-energy form of the Euler equation along a streamline. ... -

Downstream-Water-Level Control Test Results on the WM Lateral Canal
(American Society of Civil Engineers, 2010)On steep canals, distant downstream-water-level control can be challenging. The Software for Automated Canal Management was developed, in part, to test various distant downstream water-level controllers. It was implemented ... -
Water Table Management to Improve Drainage Water Quality in Semiarid Climatic Conditions of Iran
(American Society of Civil Engineers, 2009)A lysimeter study was conducted in the field in Karaj, Iran to investigate the effects of water table management on water quality of subsurface drainage effluents. Drain volumes, nitrate-N concentration, phosphorus ... -

Surface and Subsurface Flow through Block Ramps
(American Society of Civil Engineers, 2009)Block ramps are permeable hydraulic structures. Flow that enters the block ramp infiltrates between the blocks and eventually on the porous base material on which the ramp is posed. The percentage rate of subsurface flow ... -
Transitional Flow between Orifice and Nonorifice Regimes at a Rectangular Sluice Gate
(American Society of Civil Engineers, 2009)The hydraulic transition between nonorifice and orifice flow regimes at a rectangular sluice gate was analyzed to determine the value of a coefficient
