The digital geologic map of Colorado in ARC/INFO format: Part A. Documentation
Gregory N. Green
1992, Open-File Report 92-507-A
This geologic map was prepared as a part of a study of digital methods and techniques as applied to complex geologic maps. The geologic map was digitized from the original scribe sheets used to prepare the published Geologic Map of Colorado (Tweto 1979). Consequently the...

A generalized finite-difference formulation for the U.S. Geological Survey modular three-dimensional finite-difference ground-water flow model
Arlen W. Harbaugh
1992, Open-File Report 91-494
The U.S. Geological Survey's Modular Ground-Water Flow Model assumes that model nodes are in the center of cells and that transmissivity is constant within a cell. Based on these assumptions, the model calculates coefficients, called conductance, that are multiplied by head difference to determine flow between cells. Although these are...

The ground-water-level monitoring network in Iowa
R.B. Lambert
1992, Open-File Report 92-27
The ground-water-level monitoring network in Iowa consists of 202 wells completed in the principal bedrock and surficial aquifers that supply ground water to numerous users throughout the State. The bedrock aquifers include the Cambrian-Ordovician aquifer system, the Silurian-Devonian aquifer, the Mississippian aquifer, localized Pennsylvanian aquifers, and the Dakota aquifer. The...

Estimating the amount of gas hydrate in marine sediments in the Blake Ridge area, southeastern Atlantic margin
Myung W. Lee, William P. Dillon, Deborah R. Hutchinson
1992, Open-File Report 92-275
A relative amount of gas hydrate in marine sediments can be estimated by use of either interval velocity or amplitude blanking in seismic profiles. Under the assumption of constant concentration of hydrate irrespective of porosity, the average bulk hydrate amounts for the lower portion of marine sediments above the bottom...
