Multiobjective Decision Theory ? Decision Support Systems with Embedded Simulation Models
The concepts of multiobjective decision making utilizing embedded computer simulation models and dimensionless scoring functions are described in the context of a decision support system...

A Study of a Flood Control Levee Swamp System
In an attempt to reconstruct the events of the more than 100-year 1987 New Year's Eve storm that occurred on Oahu, Hawaii, an analysis of a complicated overland flow phenomenon...

Cal Poly Model Canal
The Cal Poly Model Canal (located at the Water Delivery Facility, Irrigation Training and Research Center, California Polytechnic State University, San Luis Obispo, CA) was built to accommodate...

Modelling Automatic Upstream Control with SIMCAR
The model SIMCAR solves the gradually varied unsteady flow in a branched canal network with upstream control, with particular attention given to the simulation of the AMIL radial gates....

Field Application of Transient and Steady-State Canal Models in Thailand
A transient (unsteady) flow model for simulating the hydraulics in irrigation canal networks was developed and tested in Thailand. A steady-state hydraulic model was subsequently developed...

The ASCE task committee on 'Irrigation Canal System Hydraulic Modeling' examined a number of the computer programs available for simulating unsteady open-channel...

Multicriterion Strategic Planning for Improved Irrigation Delivery Performance
An approach for assessing alternative strategies for improving an irrigation water delivery system in the context of multiple planning criteriais applied to the Alamosa River and La Jara...

The NPUSM (Narmada) Model for Modeling Canal Flows
The NPUSM computer program was developed for the analysis of unsteady flows in canals with various types of canal structures to evaluate the Narmada Canal system in Gujarat, India. The...

SRFR?A Model of Surface Irrigation?Version 20
The computer program, SRFR, comprises a mathematical model of flow in furrows, basins, and borders. It is designed for systematic, repeated application in the solution of design and management...

Two-Dimensional Analysis of Furrow Infiltration
A general applicable two-dimensional unsaturated-saturated model for transient soil-water flow conditions in heteogeneous soils was developed. The water flow model was applied to simulate...

Optimization of Furrow Infiltration Parameters from Advance Times and Advance Rates
Optimal design and management of surface irrigation systems requires detailed knowledge of field-wide infiltration. Evaluating infiltration parameters is difficult due to temporal and...

Tributary Pollutant Effects in the Urban Stream Network
With considering unsteady flow and backwater effects, a linear water quality model is developed based on the finite difference approximation. The model is composed to two components which...

Flexible Supply Schedule Missing Link for Effective Surface Irrigation and Automation
Surface irrigation methods - furrow and border-strip are generally thought of as being inefficient and labor intensive. Careful evaluations have shown that as methods they can be very...

Enhanced Multi-Dimensional Modelling of Marshes and Wetlands
This paper summarizes the verification and application of a two-dimensional finite element model capable of simulating the complex circulation characteristics in marshes and wetlands for...

Testing a Method-of-Characteristics Model of Three-Dimensional Solute Transport in Ground Water
A new three-dimensional model of solute transport in groundwater that is based on a widely used two-dimensional method of characteristics model and is coupled to a modular finite-difference...

Evaluating Probability Measures Related to Subsurface Flow and Transport: Overview of Technical Considerations and Modeling Philosophy
Probabilistic modeling approaches are being used increasingly in order to carry out quantified risk analysis and to evaluate the uncertainty existing in subsurface flow and transport analyses....

Predicting Incipient Fluidization of Fine Sands in Unbounded Domains
Fluidization systems in the coastal environment consist of a water pumping system and a source pipe buried in or near a tidal inlet to maintain a channel or to aid in sand bypassing. If...

Sensitivity Analysis of a Ground-Water-Flow Model
A sensitivity analysis was performed on 18 hydrological factors affecting steady-state groundwater flow in the Upper Floridan aquifer near Albany, southwestern Georgia. Computations were...

Measurement and Analysis of Hydraulic Conductivity Variability of a Heterogeneous Aquifer
The spatial variability of hydraulic conductivity of a shallow alluvial aquifer was investigated using borehole flowmeter measurements. The study was conducted at the site of a large-scale...

An Energy Approach to the Analysis of Partially-Saturated Flow
When fluid passes into or out of an aquifer, work is done at the boundaries which is partly used to change the internal energy of the system and partly to overcome resistance to flow....
