A progress report on estuary modeling by the finite-element method
William G. Gray
1978, Open-File Report 78-479
Various schemes are investigated for finite-element modeling of two-dimensional surface-water flows. The first schemes investigated combine finite-element spatial discretization with split-step time stepping schemes that have been found useful in finite-difference computations. Because of the large number of numerical integrations performed in space and the large sparse matrices solved, these...

Summary appraisals of the Nation's ground-water resources; Alaska
Chester Zenone, Gary S. Anderson
1978, Professional Paper 813-P
Alaska has enormous surface-water resources, but many of the streams are frozen for most of the year and most contain glacial silt that makes them unacceptable for human use. These factors lend special significance to ground water as a water-supply source, even though perennially frozen ground (permafrost) profoundly modifies ground-water...
