APSAS; an Automated Particle Size Analysis System
Lawrence J. Poppe, A.H. Eliason, J.J. Fredericks
1985, Circular 963
The Automated Particle Size Analysis System integrates a settling tube and an electroresistance multichannel particle-size analyzer (Coulter Counter) with a Pro-Comp/gg microcomputer and a Hewlett Packard 2100 MX(HP 2100 MX) minicomputer. This system and its associated software digitize the raw sediment grain-size data, combine the coarse- and fine-fraction data into...
Ground-water levels in the Columbia River basalt and overlying materials, spring 1983, southeastern Washington
H. H. Bauer, John J. Vaccaro, R. C. Lane
1985, Water-Resources Investigations Report 84-4360
A 2 1/2-year study of the Columbia Plateau in Washington was begun in March 1982 to define spatial and temporal variations in dissolved sodium in aquifers of the Columbia River Basalt Group and to relate these variations to the groundwater system and its geologic framework. This report is part of...
Determination of diffusivities in the Rustler Formation from exploratory-shaft construction at the Waste Isolation Pilot Plant in southeastern New Mexico
Ken Stevens, Walt Beyeler
1985, Water-Resources Investigations Report 85-4020
The construction of an exploratory shaft 12 feet in diameter into the Salado Formation (repository horizon for transuranic waste material) at the Waste Isolation Pilot Plant site in southeastern New Mexico affected water-levels in water-bearing zones above the repository horizon. By reading the construction history of the exploratory shaft, an...
Effects of artificial recharge on the Ogallala aquifer, Texas
Richmond Flint Brown, W.S. Keys
1985, Water Supply Paper 2251
Four recharge tests were conducted by injecting water from playa lakes through wells into the Ogallala Formation. Injection was by gravity flow and by pumping under pressure. At one site, 34-acre feet of water was injected by gravity and produced a significant increase in yield of the well. At a...
Ground-water contribution to the salinity of the Upper Colorado River Basin
J. W. Warner, F.J. Heimes, R.F. Middelburg
1985, Water-Resources Investigations Report 84-4198
A study was conducted to estimate the contribution of groundwater and other natural sources to the salinity of streamflow in the Upper Colorado River Basin. Salt-load estimates were derived from a mass balance using measurements of quantity and quality of base streamflow. Groundwater inflow was considered to represent the bulk...
