Development and testing of highway storm-sewer flow measurement and recording system

A comprehensive study and development of measuring instruments and techniques for measuring all components of flow in a storm-sewer drainage system was undertaken by the U.S. Geological Survey under the sponsorship of the Federal Highway Administration. The study involved laboratory and field calibration and testing of measuring flumes, pipe insert meters, weirs, electromagnetic velocity meters as well as the development and calibration of pneumatic-bubbler pressure transducer head measuring systems. Tracer-dilution and acoustic flow meter measurements were used in field verification tests. A single micrologger was used to record data from all the above instruments as well as from a tipping-bucket rain gage and also to activate on command the electromagnetic velocity meter and tracer-dilution systems.

Stormwater-runoff data for a multifamily residential area, Dade County, Florida

Rainfall, stormwater discharge, and water-quality data for a multifamily residential area in Dade County, Florida, are summarized in this report. Loads for 19 water-quality constituents were computed for runoff from 16 storms from May 1977 through June 1978. The 14.7 acre basin contains apartment buildings with adjacent parking lots. The total surface area consists of 70.7 percent impervious material.

Stormwater-runoff data for a commercial area, Broward County, Florida

Rainfall, stormwater discharge, and water-quality data for rainfall and runoff are summarized for a commercial area in Fort Lauderdale, Florida. Loads for 20 water-quality constituents were computed for runoff from 31 storms between May 1975 and June 1977. The basin of 20.4 acres contains a shopping center with adjacent parking, and is 97.9 percent impervious.

Instrumentation of urban hydrology monitoring sites in southeast Florida

An instrumentation system developed and built in laboratories of the U.S. Geological Survey, Reston, Va., has been used since 1974 to collect synchronized rainfall, runoff, and water-quality data from urban basins. A number of field modifications were made to adapt the system to local hydrologic conditions and for collection of data on about 350 rainstorms at four sites in south Florida. The instrumentation system measures rainfall at three sites, records two pressure or water-level readings for flow computations, and collects and refrigerates up to 24 water samples and rainfall-quality samples. Rainfall and runoff data are recorded every 36 seconds on a six-channel analog recorder so that all variables are time-synchronous. Flow in the storm sewer is computed from pressure measurements in a U-shaped venturi-type constriction or, when the constriction is not used, from water levels. (Kosco-USGS)

Urban stormwater runoff data for a residential area, Pompano Beach, Florida

Rainfall, storm-sewer discharge, and water-quality analyses of storm runoff are summarized for a single-family residential area near Pompano Beach, Florida. The area of the drainage basin is 41 acres of which 61 percent is pervious sod lawns and 39 percent is impervious roofs, driveways and streets. The land surface is nearly flat with a gentle, eastward slope. Storm runoff flows eastward along grass swales into a sewer collection system on the eastern boundary of the area that in turn joins a 36-inch diameter storm drain. Runoff loads of 12 or more water-quality constituents were computed for 32 storms between April 1974 and September 1975. Chemical analyses of rainfall for 3 storms are included. (Woodard-USGS)

Stormwater-runoff data for a highway area, Broward County, Florida

Rainfall, stormwater discharge, and water-quality data for both rainfall and runoff are summarized for a highway area near Pompano Beach, Florida. Loads for 20 water-quality constituents were computed for the runoff from 41 storms between April 1975, and July 1977. The basin of 58.3 acres contains a 3,000 ft segment of highway and is 36 percent impervious.
