This report is an outgrowth of permafrost and geologic field studies now in progress in the southeastern Copper River basin, Alaska and is in response to inquiries for information on permafrost and ground-water conditions. Various private and governmental groups have encountered severe differential settlement of building foundations on permafrost, and...
Water levels in observation wells in Nebraska during 1955
C.F. Keech
1956, Open-File Report 56-70
The objective of the dbservation-well program in Nebraska is to provide an evaluation of the status of the ground-water supplies. Many uses for water-.level data are known but not all potential uses can be forseen. Among the important uses are the following:To indicate the status of ground water in storage...
Relationship of sediment discharge to streamflow
B. R. Colby
1956, Open-File Report 56-27
The relationship between rate of sediment discharge and rate of water discharge at a cross section of a stream is frequently expressed by an average curve. This curve is the sediment rating curve. It has been widely used in the computation of average sediment discharge from water discharge for periods...

Diatremes and craters attributed to natural explosions
Eugene Merle Shoemaker
1956, Trace Elements Memorandum 1090
Diatremes - volcanic pipes attributed to explosion - and craters have been studied to infer the ultimate causes and physical conditions attending natural explosive processes. Initial piercement of diatremes on the Navajo reservation, Arizona was probably along a fracture propagated by a high-pressure aqueous fluid. Gas rising at high velocity along...
