1980, Circular 850-A
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...
Evaluation of remote hydrologic data-acquisition systems, west-central Florida
J.F. Turner Jr., W. M. Woodham
1980, Water-Resources Investigations Report 79-102
The study provides an evaluation of the hydrologic applications of a land-line and two satellite data-relay systems operated during 1977-78 in the Southwest Florida Water Management District. These systems were tested to evaluate operational and reliability characteristics. Telephone lines were used to relay data in the land-line system, and the...
The accuracy of selected land use and land cover maps at scales of 1:250,000 and 1:100,000
Katherine Fitzpatrick-Lins
1980, Circular 829
Land use and land cover maps produced by the U.S. Geological Survey are found to meet or exceed the established standard of accuracy. When analyzed using a point sampling technique and binomial probability theory, several maps, illustrative of those produced for different parts of the country, were found to meet...

1980, Open-File Report 80-437
The most productive aquifers in the Fishkill-Beacon area, Dutchess County, N.Y., are the sand and gravel beds in the northeast corner of the area and along the valleys of Fishkill and Clove Creeks. The average yield of these aquifers to wells is 190 gal/min (gallons per minute). The most productive...

Hydrology of the Chicod Creek basin, North Carolina, prior to channel improvements
Clyde E. Simmons, Mary C. Aldridge
1980, Open-File Report 80-680
Extensive modification and excavation of stream channels in the 6-square mile Chicod Creek basin began in mid-1979 to reduce flooding and improve stream runoff conditions. The effects of channel improvements on this Coastal Pain basin 's hydrology will be determined from data collected prior to, during, and for several years...
