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...
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,...
Application of the New SCS Time of Concentration Method
The second edition of the Soil Conservation Service (SCS) TR-55, published in June 1986, introduces a new method for calculating the time of concentration for storm runoff flowing through...
Some New Snyder Type Coefficients for Small Watersheds
Data collected on the Goodwin Creek watershed has produced a continuous hydrologic record from 37 rain gages and runoff record from 14 runoff stations within a drainage area of 8. 26 sq...
Impact of Temperature on Columbia River Winter Floods
During the course of an extensive study of the Columbia River drainage to evaluate a major levee system near Portland Oregon, it was noted that flood runoff produced by winter storms with...
USDA-Water Erosion Prediction Project (WEPP)
The USDA-Water Erosion Prediction Project (WEPP) will develop improved erosion prediction technology based on modern hydrologic and erosion science that will be process-oriented and conceptually...
Automatic Calibration of Conceptual Rainfall-Runoff Models
An automatic calibration strategy applied to land and channel components of the National Weather Service River Forecast System is outlined. Aspects discussed include the objective function...
Time Base of a Hydrograph
For design projects in water resources, a hydrograph is commonly used to determine the required flood volumes. The time base of a hydrograph is a crucial parameter in such studies, and...
An Expert System for Snowmelt Runoff Modeling and Forecasting
An expert system has been designed and is being built for predicting snowmelt runoff. The expert system mimics an experienced hydrologist by assisting the user in preparing data input,...
Performance of a Deterministic Storm Runoff Model
The paper discusses model comparisons based on a Tulsa, Oklahoma, case study. Modeling strategies were explored, four of which were modeled in detail because of the extremes in range of...
Remote Sensing Applications in the Model of Runoff Formation in Excess of Storage
The model of runoff formation in excess of storage applied in some humid regions of China is revised in this paper, so that the model can adopt the information provided by Landsat remote...
Precipitation Analysis in Clark County, Nevada
The Clark County, Nevada Department of Public Works retained Black & Veatch in March 1985 to conduct a study of the Flamingo Wash and to recommend flood protection facilities,...
Design Storms for Urban Drainage
The characteristics of design storms for urban drainage are reviewed. There are indications that, under certain conditions, design storms produce runoff simulation results which are equivalent...
Characteristics of Intense Storms in Kansas
This paper examines point-rainfall characteristics of intense storms in Kansas. Hourly rainfall records were analyzed for 1006 intense storms selected from some 1800 station-years of data....
Selecting a Stormwater Service Level for Urban Control
Recently, more and more emphasis is being placed on the maintenance of pre- and post-development runoff peaks from a specified design storm. The limit on post-development flood peaks requires...
Use of Continuous Simulation Versus the Design Storm Concept for Water Quality
The validity of the design storm concept has been challenged by several investigators since the development of computer simulation models. Of particular interest are the studies that compare...
