Development of Flood Peak Regression Equatins for Small Watersheds in Southwest Florida
Hydrologic investigations were performed on the Belle Meade-Royal Palm Hammock area in Collier County, Florida. The study area, encompassing approximately 79 square miles (205 km**2),...
Tampa Does It with Mirrors
As one of the nation's fastest growing cities, Tampa needed far more public works dollars. But the traditional source, the real estate tax, can no longer be relied on so heavily,...
Surface Runoff Water Quality from Contaminated Dredged Material Placed Upland
Bioassay and associated tests have been developed and are being refined to assist in the evaluation of the environmental impact of dredged material disposal alternatives. Simulated rainfall-surface...
High Sediment Concentrations Require High In-Channel/Supply of Sediment
Flows with high sediment concentrations (greater than 10 percent by weight) most commonly occur either as debris flows in steep channels throughout the world, or as hyperconcentrated flows...
Design Accuracy of Stormwater Detention Basins
While the stormwater detention basin is the most frequently used method for controlling runoff from developing areas in the United States, there appears to be no statement of the probable...
Outlet Hydraulics vs. Storage Requirements
In many cases developers must use a portion of their land for temporary detention of storm runoff in order to comply with local ordinances. A simple method is outlined which yields the...
Detention Pond Outlet Design for Pollution Control
Stormwater runoff detention ponds were originally developed for the control of flooding and the designs of the outlet control structure must be modified to obtain pollution control objectives....
CN Approach to Water Budgets for Small Watersheds
In some states, issuance of a surface mining permit is dependent upon an assessment of the current hydrologic baseline of the area to be mined and of the probable future impacts of mining...
Decreases in Runoff and Sediment Yield by Drainage
Runoff and sediment yield from three small agricultural watersheds were measured during four winter rainfall seasons. Following two rainfall seasons of data collection, a subsurface drainage...
Snowmelt Runoff Models for Water Supply Forecasting
Remote sensing is changing the approach in snowmelt runoff modelling. Instead of a simulated snow cover, the areal extent of the real snow cover can be periodically evaluated. Adaptation...
Forecasting for Management of Spring Runoff in the Columbia River System
The National Weather Service, Corps of Engineers, and Bonneville Power Administration are affiliated in the 'Columbia River Forecast Service' (CRFS) to more efficiently...
Water Supply Supplemented by Airport Storm Runoff
The quality of natural and induced storm water runoff from Oahu's Honolulu International Airport (HIA) and four outer island airports in Hawaii was evaluated for water supply...
Goals and Objectives in Design of Detention Outlets
Goals are the broad general purposes of the detention pond and its outlet works. A typical goal for a detention pond would be to help manage storm runoff so as to maintain historic conditions...
Progress Since 1979 in Canada
The report that follows describes the Canadian progress in urban hydrology research and in applications of research findings during the period from 1979 to 1983. The main topics include...
New Developments in Urban Hydrology in France from 1979 to 1982
The period of 1979-1982 is characterized by an important growth of the number of research studies, and financial investments for practical applications of research results. That growth...
Urban Runoff Research in Poland - Progress Since 1979
Research concerning urban hydrology in the scope necessary for drainage and urban runoff is financed in Poland within the framework of the Government Research Program Development and utilization...
Current Status of Urban Hydrology in Japan
After World War II the devastated Japanese landscape was ravaged repeatedly by heavy typhoons causing severe damages. Nevertheless, a hydrological data acquisition system was not adequately...
State of Art in Urban Hydrology in Switzerland
The research in urban hydrology in Switzerland does not result from a national organized and planned will, to solve hydrological problems (quantity and quality) due to urbanization. In...
Urban Hydrology Progress Since 1979 in the U.S.
Much of the progress in urban hydrology in the U. S. occurred before 1979. Some of the results of activities initiated or reported before that date are just becoming widely known, however....
Urban Hydrology
National progress reports on urban hydrology are presented. These reports include assessments of advances that have taken place in the past five years, what progress has been made and...
