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...
An Assessment of Input Variables to the Penman-Monteith Equation Using Canopy Reflectance Measurements
Observing the form of the Penman-J.L. Monteith equation, it can be seen that several terms could be potentially estimated from remotely sensed data. These include: net radiation, canopy...
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)...
A Modern Approach to the Design of Grassed Channels
The design of grassed channels can be based on modern fluid mechanics principles. The resistance to flow in a grassed channel is linked directly to the relative roughness of the flow through...
Computation of Unsaturated Soil Parameters Using Upward Infiltration Empirical Data
The relationship between soil moisture content and hydraulic conductivity with the soil tension be defined to simulate unsaturated flow in a porous media. Direct measurements of these...
Effect of Water Depth and Groundwater Table on Infiltration from Recharge Basins
The actual effect of water depth on infiltration depends on the depth to groundwater and on whether the wetted perimeter of the basin is clean or covered by a clogging layer of fine particles...
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...
Rehabilitation of Water Wells
The main causes of declining well yield are biological growths, mechanical clogging and chemical encrustation. Because the treatment of the causes of encrustation and clogging is expensive...
An Evaluation of the Large Mammal Entry/Escape Steps Coachella Canal In-Place Lining Project
This study evaluated the effectiveness of a new system of large mammal entry/escape steps as part of the environmental investigations for the Coachella Canal In-place Lining Prototype,...
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...
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...
