Rescuing the Everglades
After a century of trying to control Florida's Everglades, water management officials have decided that cooperating with nature is better. A new strategy known as the Rainfall...

A Stochastic-Conceptual Reservoir Inflow Forecasting Model
The development of a method to improve real-time forecasting of reservoir inflows for the purpose of minimizing water loss through spillage is presented. Streamflow forecasts are computed...

New Concepts for Prelininary Hydropower Design
Hydropower generation on steep mountainous streams where storage is impractical can usually be made economical if: the flow duration curve shows sufficient energy available in the high...

Co-ordinated Microcomputer-Based Rain Data Network and Modeling Environment
A co-ordinated microcomputer controlled rainfall collection network has been designed which includes drop counting precipitation sensors, tipping bucket raingauges, Z80-A microprocessor...

Rainfall-Loss Parameter Estimation for Illinois
The U. S. Geological Survey is currently conducting an investigation to estimate values of parameters for two rainfall-loss computation methods used in a commonly used flood-hydrograph...

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,...

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....

Real-Time Monitoring and Flood Forecasting
An automated flood warning system is now serving the 2,700,000 residents of Houston, Harris County, Texas. Real-time rainfall and river level data from more than 150 sensors are automatically...

Prediction of Sediment Yield for Southern California Watersheds
The objective of this paper is to present a scientific method based on multiple linear regression analysis between the sediment yield per square mile and a number of physically realistic...

Storm Dynamics in the Lake Ontario Region
A program package, RAINPAK, was written to develop appropriate rainfall input, based on concepts of the physical processes behind the temporal and spatial distribution of storm rainfall...

Intense Storms and the Runoff Coefficient
During prolonged, intense storms the runoff coefficient increases in value and approaches one irrespective of the vegetation and soil characteristics of the watershed. As the runoff coefficient...

Real Time Data Acquisition in Structural Testing
The process of data collection in real time for structural engineering can be generalized into a process called the real time sequence. The sequence has three major phases: preliminary...

Effectiveness of Erosion Control
Erosion control in the urban environment is addressed from the perspective of the mechanisms of erosion. The primary cause of erosion in urban areas is flowing water. Measures are identified...

Cut-and-Fill Becomes Cut-and-Drain
The U.S. Navy's facility in Subic Bay, Philippines, is in a mountainous area which experiences 182 inches of rain per year. These factors plus weak soil, made necessary an...

Proportional Weirs for Stormwater Pond Outlets
Many jurisdictions mandate that new developments must not cause runoff to flow downstream, during and after rainfalls, at rates higher than preconstruction. A common for controlling runoff...

Santa Barbara Hydrograph with Green-Ampt Infiltration
Numerous models are available to estimate rainfall-induced runoff from watersheds. The leading criteria in model selection is often reproducibility. Models that are reproducible are often...

Evaluation of Runoff Prediction Using Synthetic Rainfall and CREAMS
Of all the climatological data, rainfall is the variable to which a watershed responds most significantly. The amount and sequence of occurrence of rainfall are most important in the prediction...

Surface Erosion Control on Roads in Granitic Soils
The impact of forest road construction on water quality and fish habitat is a serious problem for engineers, hydrologists, and foresters. Control of surface erosion is an important and...

Interrelating Infiltration Measurements
Field measurements of infiltration rates are frequently used to index environmental conditions, soil hydrology, and the potential for rainstorm response. However, the variety of methods...

Forestation in Northeastern Brazil and Its Influence on Quantity and Quality of Runoff
A study is being conducted in Northeastern Brazil, at Cruzeta, in the Semi-Arid Tropic, to estimate runoff and soil displacement caused by precipitation and the influence of vegetation...
