The Water Erosion Prediction Project (WEPP) watershed model is a distributed continuous simulation model developed to compute the spatial and temporal distribution of erosion and deposition...
An Interactive Computer Model to Simulate Water Quality of Streamflow from Forested Watersheds in Arizona
To better formulate water resources policies and management strategies, a computer model that simulates concentrations of dissolved chemicals in snowmelt-runoff from forested watersheds...
Hydrologic Effects of Brush to Grass Conversion
A physically based rainfall-runoff model is used to detect hydrologic response to artifically induced vegetation changes on a semiarid watershed. Model parameters are optimized using a...
Watershed Hydrograph Simulation Through Dendritic Channel Networks
In this paper, a linear dendritic simulation model based on the finite difference implicit scheme is presented. In this model, a dendritic matrix solution algorithm for simultaneous solution...
Precipitation Variability Effects on Modeled Soil Water Deficits
Effective management of forages in steep Appalachian pastures requires an understanding of hydrologic and microclimatic processes on the area. This study was conducted to determine the...
Summary Report: Evaluation Criteria for Watershed Models
After an extensive literature review, the Task Committee recommends that, in addition to graphical plots, modelers use three simple goodness-of-fit criteria for evaluating continuous hydrograph...
Optimizing Wet-Dry Precipitation Probabilities for Improving Plant Establishment
Studies have shown that the chances of achieving successful seedling establishment in arid and semiarid regions is dependent upon the pattern of favorable wet-dry precipitation sequences....
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...
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...
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...
Deadly Debris Flows on I-5 Near Grapevine, CA
A series of debris flows inundated the southbound lanes of interstate Highway 5 (1-5) approximately 110 km (70 mi) NW of Los Angeles, California, between Fort Tejon and Grapevine, early...
