Design of Seepage Fields for Stormwater Disposal
Stricker Pond is a shallow twenty-acre kettle hole pond in south-central Wisconsin. The pond receives runoff from a closed watershed that is rapidly undergoing low density residential...
TR-55 Microcomputer Implementation
Microcomputer software is now available which implements the Soil Conservation Service's recently revised 'Urban Hydrology for Small Watersheds',...
Role of Surficial Aquifer in Barrier Island Streamflow Generation
Monitoring results are presented for an experimental watershed located on a South Carolina barrier island. Rainfall, streamflow and well data indicate streamflow occurs due to interaction...
A Possible Definition of the Input Function for a Rainfall-Runoff Model with Lumped Parameters
It may be useful to introduce, instead of a 'mean areal rainfall', another input function, defined as that input which is transformed by the model into a known...
A Geomorphologically-Based Runoff Prediction Model: Case Study of Two Gauged Watersheds in Saudi Arabia
Using the Geomorphologic Instantaneous Unit Hydrograph (GIUH) and via the convolution transformation, a linear discharge hydrograph prediction model is obtained. Infiltration in streams...
Emerson, Iowa Flood Warning System
A flood warning system was installed in 1985 by the Corps of Engineers at Emerson, Iowa as part of Emerson, Iowa Flood Control Project on Indian Creek. The warning system consists of two...
Effect of Length of Precipitation Record on Recharge Estimates
The effect of the length of precipitation record on groundwater recharge estimates is examined using data from eleven precipitation gages located on the Nevada Test Site. It is concluded...
Underground Drainage of Urban Runoff from Natural Depressions
A unique subsurface system was designed and implemented for draining such a natural depression in the City of West Lake Hills, Texas. This subsurface drainage system uses a part of the...
Evaluation of Stormwater Management Structures in Maryland Proportioned by SCS TR-55
Various state and local agencies in Maryland are requiring that the Soil Conservation Service Technical Release 55 be used to evaluate impact of urbanization on peak rates of discharge....
Design Criteria for Detention Basins in Urban Drainage
Many communities require the use of detention basins in order to manage the increased runoff discharge in all newly developing watersheds. The authors have shown earlier that the typical...
Detention Basin Design Using Continuous Simulation
A continuous simulation model is proposed for use in the design of detention basins. The model accepts standard National Weather Service hourly rainfall data as input. The hourly rainfall...
The Storage Matching Technique of Detention Basin Design
In recent years, use of continuous rainfall - runoff simulation with historic rainfall data has become much more popular for the design of detention basins and reservoirs. While it may...
Flood Operation Studies of the Valdesia Reservoir System in the Dominican Republic
The Valdesia reservoir system, located on the Nizao River in the Dominican Republic, is designed to provide irrigation water to the Nizao project areas and hydroelectric energy to the...
Flood Forecasting Using Local Resources
A dynamic wave flood routing computer program has been used to develop a flood forecasting model for a 5000 mi**2 watershed in lower Michigan. The modeled area covers over 200 miles of...
Flood Forecasting with Minimal Data
The Corps of Engineers' HEC-1 program has been used with a specialized pre-processor program to provide interim emergency flood forecasting for a 4000 sq mi (10,360 sq km) watershed in...
Real-Time Hydrologic Modeling
The Huntington District of the Corps of Engineers is currently using daily computer modeling for guidance in regulating all nine of its major river basins. Both pool elevation and flow...
Improved SWMM Applications for Stormwater Management Master Plans: A Case Study of Virginia Beach, Virginia
A case study of a recent master plan for a 16. 5 sq mi watershed in Virginia Beach, Virginia is presented to illustrate stormwater master planning approaches. The analysis showed that...
Hydrologic Runoff Modeling of Small Watersheds: The Tinflow Model
TINFLOW is a PC-based Geographic Information System (GIS) that utilizes the Triangulated Irregular Network (TIN) and associated data structures, together with a deterministic, finite difference...
Geographic Estimation of Runoff-Model Parameters
The U. S. Geological Survey is developing techniques to estimate and evaluate unit-hydrograph and loss-rate parameter values for rainfall-runoff models using Geographic Information System...
Development, Use, and Synthesis of S-Graphs
A study to identify S-graphs from the southwestern United States has been completed. This study has resulted in the compliation of 53 S-graphs, documentation of some of the watershed characteristics,...
