Stamukhi shoals of the Arctic - some observations from the Beaufort Sea
Erk Reimnitz, Douglas K. Maurer
1978, Open-File Report 78-666
A number of linear shoals, representing pronounced topographic anomalies on the surface of the Arctic shelf, have been studied in the Prudhoe Bay area. These shoals have been referred to in several previous studies. Based on seismic reflection records, Reimnitz et al., (1972a), stated that the shoals are constructional features...

Eolian sand and interbedded organic horizons at Kealok Creek on the Arctic Coastal Plain of Alaska: possible regional implications
L. David Carter, S.W. Robinson
1978, Open-File Report 78-320
Eolian sand has long been recognized as a widespread but minor facies of supposedly dominantly marine sediments of the Gubik Formation of the Arctic Coastal Plain (Smith and Mertie, 1930; Black, 1951 and 1964; O'Sullivan, 1961). Descriptions of eolian landforms of the coastal plain have been published by several authors,...

Linear ground-water flow, flood-wave response program for programmable calculators
John Michael Kernodle
1978, Open-File Report 78-356
Two programs are documented which solve a discretized analytical equation derived to determine head changes at a point in a one-dimensional ground-water flow system. The programs, written for programmable calculators, are in widely divergent but commonly encountered languages and serve to illustrate the adaptability of the linear model to use...

1978, Open-File Report 78-528
A calibrated and verified transient flow temperature model was used to evaluate the effects of flow regulation and powerplant loadings on the natural temperature regime of the Chattahoochee River in northeast Georgia. Estimates were made of both instantaneous and average natural temperatures in the river during an eight-day period in...

Calibration of a simple oilspill trajectory model using the Argo Merchant spill
Timothy Wyant
1978, Open-File Report 78-334
An oil spill risk analysis was conducted to determine the relative envionmental hazards of developing oil in different regions of the Eastern Gulf of Mexico Outer Continental Shelf lease area. The study analyzed the probability of spill occurrence, likely paths of the spills, and locations in space and time of...
Hot, deep origin of petroleum: deep basin evidence and application
Leigh C. Price
1978, Open-File Report 78-1020
Use of the model of a hot deep origin of oil places rigid constraints on the migration and entrapment of crude oil. Specifically, oil originating from depth migrates vertically up faults and is emplaced in traps at shallower depths. Review of petroleum-producing basins worldwide shows oil occurrence in these basins...
Risk analyses for a water-supply system; Occoquan Reservoir, Fairfax and Prince William counties, Virginia
Robert M. Hirsch
1978, Open-File Report 78-452
This report demonstrates two techniques for evaluating risks in the operation of a water-supply system. Both rely on reconstructed historical streamflow data to develop estimates of the probabilities of certain specific events occurring in the future. These techniques are applied to the Occoquan Reservoir which was experiencing an unprecedented low...

Hydraulic geometry of river cross sections; theory of minimum variance
Garnett P. Williams
1978, Professional Paper 1029
This study deals with the rates at which mean velocity, mean depth, and water-surface width increase with water discharge at a cross section on an alluvial stream. Such relations often follow power laws, the exponents in which are called hydraulic exponents. The Langbein (1964) minimum-variance theory is examined in regard...
