Conjunctive Use of Surface and Groundwater
A computer model was developed by T. Sammis and Z. Samani to simulate the conjunctive use of surface and groundwater. The model consisted of a groundwater simulation subroutine and a crop...

Canal Automation for Flexibility on Sloping Canals
This project and tested a method which would allow flexible water deliveries from medium-large canals. The canal gate movement algorithm CARDD (Canal Automation for Rapid Demand Deliveries)...

Practical Approaches Used in Neutron Meter Moisture Monitoring
This paper describes a practical, appropriate methodology for utilizing neutron meter soil moisture measurements to provide irrigation management information to farmers. A neutron meter...

Evaluating Groundwater Pollution Potential Using Geographical Information Systems
A procedure for developing groundwater pollution potential maps using a geographical information system (GIS) is introduced. The concept of pollution potential mapping is discussed, along...

Expediting the Evaluation of Water-Rights Applications in the Mimbres Basin, NM
More than eighty percent of all ground water used in New Mexico is used for agriculture. The allocation of ground water in the state is the responsibility of the State Engineer. For the...

Mapping Ground-Water Sodium Adsorption Ratios in Northern Louisiana
High sodium concentration is suspected as the cause of several crop failures in the northern part of Louisiana. This study, using Geographic Information Systems (GIS) technology, was undertaken...

Near Real Time Irrigation Scheduling Using Heat Unit Based Crop Coefficients
An interactive computer program (SCHEDPEN) which utilizes growing-degree-day based crop coefficients for irrigation scheduling was developed and tested on cotton during 1988 and 1989 at...

A Hydrologic Model for Designing Border Irrigation
A hydrologic model was developed and evaluated using experimental data from two irrigation tests. First, the model was calibrated using the experimental data of one irrigation test, after-that...

Optimizing the Resources for Water Management
This proceedings, Optimizing the Resources for Water Management, contains papers presented at the 17th Annual National Conference that was...

Evolution of Drainage Criteria, Albuquerque, New Mexico
Storm drainage in Albuquerque, NM is a central issue in land development. To expedite municipal development while assuring public safety and preserving environmental attributes in a public...

Drainage Manual for Clark County, Nevada
The development of a flood control district and its associated capital improvement and regulatory programs does not by itself address drainage standards for a community. While the capital...

Comparison of Design Rainfall Criteria for the Southwest
The design of drainage and flood control facilities or the management of floodplains for alluvial fans is extremely sensitive to the design rainfall criteria that is used as input to the...

Experimental Study on the Flow Properties of Debris Flow
A new flow property model for viscous debris flow was presented in this paper. The results of the flow property model were in good agreement with the results of specific experiments. The...

Two-Dimensional Modeling of Overland Flow
Two-dimensional distributed finite element (F-E) and finite difference (F-D) models are developed to simulate storm events on arid watersheds. The F-E model uses the kinematic wave approximation,...

Two-Dimensional Modeling of Alluvial Fan Flows
A two-dimensional, flood routing model FLO-2D has been developed to route water and mudflows over unconfined surfaces. It predicts flow velocities and depths at discrete points for channel...

Flood Hazard Delineation on Alluvial Fans
Alluvial fans are significant geomorphic features of arid lands. The unconfined and dynamic nature of alluvial fans makes standard methods of delineating flood hazards unsuitable. The...

Application of the U.S.G.S. DHM for Floodplain Analysis
The two-dimensional Diffusion Hydrodynamic Model, DHM, is applied to the evaluation of floodplain depths resulting from an overflow of a leveed river. The environmental concerns of flood...

Misapplication of the FEMA Alluvial Fan Model: A Case History
The Federal Emergency Management Agency (FEMA) recently issued revised Flood Insurance Rate Maps (FIRM) for the Tortolita piedmont, located northwest of Tucson, Arizona. Floodplain delineations...

Numerical Simulation of Mudflows from the Hypothetical Failure of a Debris Blockage Lake Below Mount St. Helens, WA
This paper evaluates the characteristics of mudflow events resulting from the hypothetical breaching of a debris blockage dam using a variety of lake levels and impounded water volumes...

Some Aspects of the Mechanism of Debris Flow
As the first step of the development of a general two-phase flow model for debris flows, a simple granular model, which is considered as a special case of the two-phase flow model, is...
