Maricopa County Hydrology Procedure
The Flood Control District of Maricopa County has developed a procedure to be used for flood hydrology in Maricopa County, Arizona, and the Flood Control District has prepared a Hydrologic...
Validation of Hydrophysical Components of a One-Dimensional Lake Model
A dynamic one-dimensional lake model has been developed in alternative structures, MINLAKE and FRMPND, for water-quality control strategies and lake eutrophication studies. Hydrophysical...
Supplemental Irrigation by Runoff Farming: An Economic Assessment
A simulation model was used to evaluate the economic potential for using runoff farming techniques for growing grain sorghum at two locations in Texas. The results show that the yearly...
Biodiversity in Riparian Communities and Watershed Management
Riparian communities are demonstrated to be regional centers of biodiversity and biomass. Examples are taken primarily from bird and lizard communities in the Southwest, since these vertebrates...
Stream Bank Stability Prediction for C6 Stream Type Reconstruction
A hydraulic model investigation will be conducted to evaluate the effects of root system characteristics of three meadow plant communities on simulated bank erosion. The test will determine...
Demonstration of Watershed Management Effectiveness in Sediment Control Using Comprehensive Watershed Modeling
The Arroyo Pasajero, which drains a 500-square mile watershed in the Coastal Range of California, flows into the San Joaquin Valley, intersecting the San Luis Canal section of the California...
Modeling Erosion and Effects of Agricultural BMP's on a West Tennessee Watershed
The application of Hydrological Simulation Program FORTRAN (HSPF) to nonpoint source data was examined. The model is used to determine the effects of land management practices upon surface...
Sprinkler System Design for Frost Protection
Both undertree and overtree systems for frost protection by sprinkling are currently being used. The criteria based on experimental results and theoretical modeling have been reviewed...
Infiltration or Roughness from Surface Irrigation Advance
Over the past several decades, a significant effort has gone into the development of mathematical models of water flow over the soil surface. Significant progress has been made in prediction...
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)...
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...
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...
Design of Steel Transmission Pole Structures
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...
