Evaluation of yields of wells in consolidated rocks, Virginia to Maine
Dagfin John Cederstrom
1972, Water Supply Paper 2021
In the North Atlantic region, Virginia to Maine, yields of industrial and municipal wells are the most reliable indicators of the water-yielding potential of consolidated rocks. Generally, such wells represent efforts to develop a maximum supply of water, they are 350 to 500 feet deep, and they utilize 60 to...
Regional and other general factors bearing on evaluation of earthquake and other geologic hazards to coastal communities of southeastern Alaska
Richard Walter Lemke, Lynn A. Yehle
1972, Open-File Report 72-230
The great Alaska earthquake of March 27, 1964, brought into sharp focus the need for engineering geologic studies in seismically active regions. As a result, nine communities in southeastern Alaska were selected for reconnaissance investigations as an integral part of an overall program to evaluate earthquake and other geologic hazards...
Reconnaissance engineering geology of the Haines area, Alaska, with emphasis on evaluation of earthquake and other geologic hazards
Richard Walter Lemke, Lynn A. Yehle
1972, Open-File Report 72-229
The Alaska earthquake of March 27, 1964, brought into sharp focus the need for engineering geologic studies in urban areas. Study of the Haines area constitutes an integral part of an overall program to evaluate earthquake and other geologic hazards in most of the larger Alaska coastal communities. The evaluations...
The status of mineral resource information on the major land withdrawals of the Alaska Native Claims Settlement Act of 1971
Alaskan Geology Branch
1972, Open-File Report 72-394
This report is an analysis of the adequacy of the present level of geologic knowledge for making mineral resource potential evaluations of 126 federal land withdrawals made under the Alaska Native Claims Settlement Act. The withdrawals considered are Native village and regional deficiency areas (Sec. 11.A.3, ANCSA), classification and national...
Placer deposits of Alaska
Edward Huntington Cobb
1972, Open-File Report 72-71
Placer deposits, in addition to their intrinsic value, serve as indicators of areas of potential development of lode deposits. Any possibility that Alaska may again become an important source of metallic mineral commodities depends in part on an inventory of placer deposits and a knowledge of the geology of their...
Appraisal of shallow ground-water resources, Pueblo Army Depot, Colorado
Frank A. Welder, R. Theodore Hurr
1972, Open-File Report 72-447
The water supply for the Pueblo Army Depot, 15 miles wast of Pueblo, Colo., is obtained from wells that tap an aquifer in terrace alluvium. Withdrawals have resulted in a water-level decline of 27 feet, which adversely affects the discharge rate of individual wells. Furthermore, excessive pumpage has resulted in...
Summary of floods in the United States during 1967
J.O. Rostvedt
1972, Water Supply Paper 1880-C
This report describes the most outstanding floods in the United States during 1967. The two most destructive floods occurred in August in east-central Alaska and in September and October in southern Texas. In east-central Alaska, heavy rain on August 8-17 produced record-breaking floods near Fairbanks. Peak discharges on some streams...
Appraisal of stream sedimentation in the Susquehanna River basin
Kenneth F. Williams, Lloyd A. Reed
1972, Water Supply Paper 1532-F
The Susquehanna River presently transports about 3.0 million tons of sediment annually (110 tons per square mile). Only about 1.8 million tons of sediment enters the head of Chesapeake Bay annually because some sediment is trapped behind the power dams on the lower Susquehanna. Measured annual sediment yields from subbasins...
