Potentiometric surface of the Floridan Aquifer, Southwest Florida Water Management District and adjacent areas, September 1978
R. M. Wolansky, L. R. Mills, W. M. Woodham, C. P. Laughlin
1978, Open-File Report 78-1035
A September 1978 potentiometric-surface map depicts the annual high water-level period of the Floridan aquifer in the Southwest Florida Management District. Potentiometric levels increased 10 to 25 feet between May 1978 and September 1978, in the citrus and farming sections of southern Hillsborough, northern Hardee, southwestern Polk and Manatee Counties....
Relation of urban land-use and land-surface characteristics to quantity and quality of storm runoff in two basins in California
Marc A. Sylvester, William M. Brown
1978, Water Supply Paper 2051
Two basins (Castro Valley Creek, in Alameda County, and Strong Ranch Slough, in Sacramento County) in the San Francisco Bay and Sacramento-San Joaquin Delta region (Bay-Delta region) were sampled intensively (3-15 minute intervals) during three storms between October 1974 and April 1975. Both basins are primarily residential, but the Strong...
Water resources data for Colorado, water year 1977: Volume 3. Dolores River basin, Green River basin, San Juan River basin
Water Resources Division, U.S. Geological Survey
1978, Water Data Report CO-77-3
Water-resources data for Colorado for the 1977 water year consists of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs, and water levels and water quality of wells and springs. This report (Volumes 1, 2, and 3) contains discharge records for...
Floodflow analysis of Ninemile Creek, Onondaga County, New York
Richard Lumia, Bernard Dunn
1978, Open-File Report 78-85
A flood-stage and discharge analysis was made for a 3.61 mile reach of Ninemile Creek between Amboy and Camillus. Water-surface profiles were developed for 50-year, 100-year, and September 26, 1975 flood discharges at Camillus for four different channel conditions: (1) with four culverts at Camillus bypass and a bridge at...
Supplementary hydraulic analysis of proposed bridge site on Mohawk River, Whitesboro, New York
Richard Lumia
1978, Open-File Report 78-348
As a supplement to a 1975 report, titled "Floodflow Characteristics at Proposed Bridge Site on Mohawk River, Whitesboro, New York," by Bernard Dunn (U.S. Geological. Survey open-file report), in which the hydraulic effects of two alternative highway plans during a large-magnitude flood were evaluated, a hydraulic analysis was made for...
Pennsylvanian (Upper Carboniferous) system of Wyoming
Edwin K. Maughan
1978, Open-File Report 78-377
Pennsylvanian rocks in Wyoming comprise two stratigraphic sequences bounded by regional unconformities. Red mudstone and limestone characterize the strata in the lower sequence, and sandstone and dolomite characterize the strata in the upper sequence. Initial deposits of the lower sequence are-red mudstone probably of no older age than about middle...
Effects of urban development on the flood-flow characteristics of the Walnut Creek Basin, Des Moines Metropolitan area, Iowa
Oscar G. Lara
1978, Water-Resources Investigations Report 78-11
This report deals with the probable impact of urban development on the magnitude and frequency of flooding in the lower reach of the Walnut creek Basin.Stream-modeling techniques, which include complete definition of unit hydroqraphs and precipitation loss-rate criteria, were utilized to evaluate the effects of urban development as measured by...
