Geology of the San Francisco North quadrangle, California
Julius Schlocker
1974, Professional Paper 782
San Francisco is a heavily built up city in a region of active faults and is subject to earthquakes and landslides. In such an area careful selection of building sites and foundations is imperative. This geologic investigation of the San Francisco North quadrangle was carried out to obtain basic geologic...
Saline ground-water resources of Lee County, Florida
Durward Hoye Boggess
1974, Open-File Report 74-247
Lee County, an area of 786 square miles (1260 square kilometres) on the southwest coast of Florida, is underlain at depths greater than 400 feet (120 metres) by formations containing saline water. Two saline water-bearing zones occur within the depth interval 400 to 1,200 feet (120 to 370 metres); the...
Water resources of the Snake River watershed, east-central Minnesota
Gerald F. Lindholm, J. O. Helgesen, W.L. Broussard, D.W. Ericson
1974, Hydrologic Atlas 488
Glacial drift overlies sedimentary, igneous, and metamorphic rocks in the Snake River watershed. The Snake River, which drains an area of about 1,030 square miles, originates in an extensive area of peat bogs in the northern part of the watershed. It flows southward across gently rolling glacial terrain in which the...
Hydrology of the Dismal Swamp, Virginia-North Carolina
William Francis Lichtler, Patrick Neil Walker
1974, Open-File Report 74-39
The Dismal Swamp, on the border between eastern Virginia and North Carolina is one of the few remaining large (approximately 210,000 acres) areas of wet wilderness in the eastern United States. There has been much speculation concerning the hydrologic conditions that led to the formation of the swamp.Oaks and Coch...
Water resources of the lower St. Croix river watershed, east-central Minnesota
Gerald F. Lindholm, J. O. Helgesen, W.L. Broussard, D.F. Farrell
1974, Hydrologic Atlas 490
The lower St. Croix River watershed is an elongate area of about 930 square miles bounded on the east by the St. Croix River. The St. Croix River forms the Minnesota-Wisconsin boundary along the eastern side of the watershed. Additional drainage to the St. Croix River includes areas of about 2,500...
Summary of activities, U.S. Geological Survey Saudi Arabian project, 1950 to 1974
Thor H. Kiilsgaard
1974, Open-File Report 74-129
The U. S. Geological Survey (USGS) first began work in the Kingdom of Saudi Arabia in 1950 under the sponsorship of the Ministry of Finance and National Economy. The basic objective of the work was to investigate the mineral and water resource potential in western Saudi Arabia, but little was...
Straight line fitting of an observation path by least normal squares
William H. Kirby
1974, Open-File Report 74-187
In curtain hydro graphic problems, and perhaps in other geophysical problems, information must be collected as profiles along straight-line courses. When the inevitable deviations from perfect linearity occur, one must then find the straight line course that best approximates the actual observation path. Classical least squares (regression) does not solve...
