Rainfall-runoff modeling and preliminary regional flood characteristics of small rural watersheds in the Arkansas River basin in Colorado
Russell K. Livingston
1981, Water-Resources Investigations Report 80-112
Both recorded and synthetic rainfall-runoff and annual peak-discharge data for 17 rural watersheds were analyzed to evaluate the magnitude, frequency, and volume of floods in the plains region of the Arkansas River basin in Colorado. Flood-frequency relations from analysis of recorded data were weighted or combined with flood-frequency relations from...

Effects of the Mount St. Helens eruption on the benthic fauna of the Toutle River, Muddy River, and Pine Creek drainage basins, Washington
Luis A. Fuste
1981, Circular 850-H
During several periods of volcanic-ash eruption at Mount St. Helens, Wash., (March 30, May 25-26, May 30-June 2, and June 12-13, 1980) strong winds from the north occurred at high altitudes. As a result, the volcanic ash fell some 50 miles to the south in the Bull Run watershed, the...
Stormwater quality processes for three land-use areas in Broward County, Florida
Harold C. Mattraw Jr., Robert A. Miller
1981, Water-Resources Investigations Report 81-23
Systematic collection of rainfall, runoff, and water-quality samples from three small urban areas of Broward County, Florida, were obtained between 1974 and 1977. Stormwater loads for 30 or more storms were computed for the residential, highway, and commercial investigation areas. Stepwise, multiple, linear regression models were constructed for total nitrogen,...
Water quality of Alimagnet, Farquar, and Long Lakes in Apple Valley, Minnesota
M.R. Have, G. A. Payne, M. A. Ayers
1981, Water-Resources Investigations Report 81-40
Alimagnet, Farquar, and Long Lakes, in Apple Valley, Minnesota, were sampled from 1973-79 to determine their physical and chemical characteristics. A storm-sewer inlet to Alimagnet Lake was also sampled during two storms in 1978. The 1976-77 drought caused a more noticeable effect on the quality of the lakes than any...

The earthquake data shown on this map and listed in table 1 are a list of earthquakes that were originally used in preparing the Seismic Risk Studies in the United States (Algermissen, 1969) which have been recompiled and updated through 1979. These data have been reexamined which resulted in some...
