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...
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...
Storm Sewer Computer-Aided Design and Uncertainty
A micro-computer based storm drainage model is presented which facilitates urban storm sewer design on fast tracked construction projects. The model is an interactive Basic program using...
Hydrograph Decomposition: Using a Technical Database
Trouble shooting for infiltration/inflow (I/I) problems in a sewer system is made much easier with the aid of a computerized hydrograph decomposition methodology. A methodology has been...
The SRI Technique for Flood Frequency Analysis
This paper presents a technique for flood flow frequency analysis called the Storm Response Index (SRI), and a case study using the technique. The SRI method is based on the development...
Rainfall Results of the Florida Area Cumulus Experiment and Their Implications for Drought Problems in the South
Evidence is presented for treatment effects during the Florida Area Cumulus Experiment (FACE). The sizes of the apparent effects are a function of scale, largest for the cell scale and...
Texas Hiplex Experimental Design
Research into rainfall enhancement in Texas expanded rapidly during the 1970's with the Texas HIPLEX program. More recently, the states of Texas and Oklahoma and the United...
Evaluation of Cloud Seeding: Southern Great Plains
One of the important aspects of planned weather modification in the United States is that many operational, non-experimental cloud seeding projects have occurred since 1950. Further, several...
Principles for Coastal Zone Management in South Africa
The southern tip of the African continent is characterized by a wide variety of coastal environmental conditions, ranging from a steeply tilted topography with sub-tropical summer rainfall...
Stormwater Routing for Small Sites
Traditional hydrologic analyses and detention design procedures are too time consuming and costly to be warranted for small projects. This paper discusses a direct solution for sizing...
Tidal Flooding Study for a Seattle Watershed
The paper reports on a study to develop a correlation between rainfall volumes and tidal storm surges based on recorded rainfall and tide data. This correlation was used to establish tidal...
Real-Time Flood Forecasting on Small Computers
A real-time, rainfall-runoff, flood forecast model, developed by the Corps of Engineers Hydrologic Engineering Center (HEC), was applied to two of tributary basins in the Ohio River System....
