The 1980 Polallie Creek debris flow and subsequent dam-break flood, East Fork Hood River basin, Oregon
Gary L. Gallino, Thomas C. Pierson
1984, Open-File Report 84-578
At approximately 9 p.m. on December 25, 1980, intense rainfall and extremely wet antecedent conditions combined to trigger a landslide of approximately 5,000 cubic yards at the head of Polallie Creek Canyon on the northeast flank of Mount Hood. The landslide was transformed rapidly into a debris flow, which surged...

1984, Water-Resources Investigations Report 82-4073
A study designed to quantify and evaluate changes in runoff and sediment transport attributable to construction activities during urban development of a watershed required identification of pre-construction hydrologic conditions. Data collected before construction on a 2.81 sq m (7.28 sq km) agricultural watershed (upper Spring Creek) near Rockford, IL, show...

Common-depth-point seismic-reflection survey on the Mississippi River in the vicinity of Alton, Illinois
G. B. Tirey, R. A. Wise, E. A. Winget
1984, Open-File Report 84-81
A high-resolution seismic-reflection survey was run on the Mississippi River using marine common-depth-point (CDP), digital, and multichannel techniques in an attempt to locate a possible fault that had been interpreted by others from magnetic and land seismic data to be in the vicinity of Lock and Dam No. 26. The...

Development of a model to predict the adsorption of lead from solution on a natural streambed sediment
David Wayne Brown, John David Hem
1984, Water Supply Paper 2187
Adsorption of solutes by solid mineral surfaces commonly influences the dissolved ionic composition of natural waters. A model based on electrical double-layer theory has been developed which appears to be capable of characterizing the surface chemical behavior of a natural fine-grained sediment containing mostly quartz and feldspar. This variable surface...
Hydrologic data; North Canadian River from Lake Overholser to Lake Eufaula, central Oklahoma
J.S. Havens
1984, Open-File Report 84-808
The data contained in this report were gathered during the period 1982 to 1984 for use in constructing a digital model of the North Canadian River from Lake Overholser, in the western part of Oklahoma City, to Lake Eufaula, in eastern Oklahoma. Locations of test holes and sampling sites are...
The effect of eustatic sea-level changes on saltwater-freshwater relations in the northern Atlantic Coastal Plain
Harold Meisler, P. Patrick Leahy, LeRoy L. Knobel
1984, Water Supply Paper 2255
A finite-difference computer model was used to analyze the effect of eustatic sea-level changes on the development of the transition zone between fresh ground water and underlying saltwater in the northern Atlantic Coastal Plain. The model simulates, in cross section, the sedimentary wedge from the Delaware River estuary in New...
Investigations and research in Nevada by the Water Resources Division, U.S. Geological Survey, 1982

1984, Open-File Report 83-768
The Water Resources Division, U.S. Geological Survey, is charged with (1) maintaining a hydrologic network in Nevada that provides information on the status of the State 's water resources and (2) engaging in technical water-resources investigations that have a high degree of transferability. To meet these broad objectives, 26 projects...
Methods for the collection of geochemical data from the sediments of the tidal Potomac River and estuary and data for 1978-1980

1984, Open-File Report 84-256
In order to refine correlations of surface-wave magnitude, fault rupture length at the ground surface, and fault displacement at the surface by including the uncertainties in these variables, the existing data were critically reviewed and a new data base was compiled. Earthquake magnitudes were redetermined as necessary to make them...
