STRONG-MOTION INSTRUMENTATION OF STRUCTURES IN CHARLESTON, SOUTH CAROLINA AND ELSEWHERE.
Instrumentation of structures is part of earthquake hazard mitigation program of many institutions, including the United States Geological Survey (USGS). The USGS Strong-Motion Instrumentation of Structures Program is designed to complement other programs and to implement its own, within budget and other constraints. This paper reviews the overall national effort, cites examples of structures impl

SULFUR CONTENT OF THE COAL RESOURCES OF THE UNITED STATES: CURRENT STATUS.
The sulfur content of United States coal can be assessed using a variety of approaches. The sulfur content may be expressed in terms of total sulfur in the coal, pounds of sulfur per million Btu, or sulfur remaining after reduction by coal preparation. In addition, sulfur content may be applied to the demonstrated reserve base or to coal resource estimates. Unfortunately, current data bases do not

THERMAL-ENERGY STORAGE IN A DEEP SANDSTONE AQUIFER IN MINNESOTA: FIELD OBSERVATIONS AND THERMAL ENERGY-TRANSPORT MODELING.
A study of the feasibility of storing heated water in a deep sandstone aquifer in Minnesota is described. The aquifer consists of four hydraulic zones that are areally anisotropic and have average hydraulic conductivities that range from 0. 03 to 1. 2 meters per day. A preliminary axially symmetric, nonisothermal, isotropic, single-phase, radial-flow, thermal-energy-transport model was constructed

U. S. GEOLOGICAL SURVEY'S SIDE-LOOKING AIRBORNE RADAR PROGRAM: THE ALASKAN CONNECTION.
The U. S. Geological Survey (USGS) has become a major source of side-looking airborne radar (SLAR) data as a result of a Congressional mandate in 1980 to 'begin the use of side-looking airborne radar for topographic and geologic mapping, and geological resource surveys in promising areas, particularly Alaska. ' In 1982, SLAR images were acquired, with a northwest look direction of almost 13,000 km

URBAN STORMWATER-QUALITY INVESTIGATIONS BY THE USGS.
U. S. Geological Survey (USGS) urban stormwater investigations, in cooperation with local and Federal agencies, have produced significant national data bases of information and enhanced understanding of urban hydrologic processes. Studies in progress include statistical regionalization of urban stormwater quality, the effects of stormwater detention on water quality, ways of improving instrumentat

USE OF SPACE TECHNOLOGY IN FEDERALLY FUNDED LAND PROCESSES RESEARCH IN THE UNITED STATES.
A review of the use of space technology in federally funded earth science research in the US was carried out in 1985 by the President's Office of Science and Technology Policy. Five departments and three independent agencies, representing the primary earth science research agencies in the Federal government, participated in the review. The review by the subcommittee indicated that, while there is

USGS NATIONAL MAPPING PROGRAM IN ALASKA--A STATUS REPORT.
The U. S. Geological Survey has been involved in mapping in Alaska since the late 1800's. The initial mapping projects were principally in support of geologic or hydrologic studies. In the late 1940's, responsibility for Alaska mapping was assigned to the Geological Survey's Rocky Mountain Mapping Center and a comprehensive and systematic mapping effort was undertaken. This effort was principally

VISCOPLASTIC FLUID MODEL FOR DEBRIS FLOW ROUTING.
This paper describes how a generalized viscoplastic fluid model, which was developed based on non-Newtonian fluid mechanics, can be successfully applied to routing a debris flow down a channel. The one-dimensional dynamic equations developed for unsteady clear-water flow can be used for debris flow routing if the flow parameters, such as the momentum (or energy) correction factor and the resistanc

Development of a computerized wetlands mapping data base for use in section 404 jurisdictional determinatins in San Francisco Bay
Development and habitat alteration in the San Francisco Bay-Delta system have placed the remaining wetlands in jeopardy. The Bay-Delta wetlands will be mapped in a joint project of the U. S. Environmental Protection Agency (EPA) and the U. S. Fish and Wildlife Service (FWS). Maps at a 1:24,000 scale will be produced for the entire study area. High altitude color infrared photography from 1985 and
