Article
Monitor wells are frequently sealed using a cement–bentonite grout mixture because it is believed that the addition of bentonite (1) reduces shrinkage of the cement, (2) increases cement plasticity, (3) reduces curing temperatures, and (4) reduces grout weight. The design of a compound grout appears to be simple: add a fixed percentage of premium b...

Numerous debris-flow events occurred along the Wasatch Front near Salt Lake City, Utah, during the springs of 1983 and 1984. These flows were distinctly different from the previous damaging flows of 1923 and 1930 which were related to cloudburst thunderstorms. The 1983 and 1984 flows were related to the rapid melting of an above average snow pack....

A survey of 446 brick-veneer, single-family homes in College Station, Beaumont, San Antonio, and Waco, Texas, shows that the geology of the home site greatly influences the expansive potential of a soil profile. Effective plasticity index is used as a measure of a soil's shrink-swell potential; however in College Station the geological conditions p...
Article
A value, based on costs and risks associated with geologic factors, can be established for tracts of land. When displayed on a map, these factors will be expressed in terms of economic value. The map is a "high-low" land-value map that identifies land having high costs and risks as low-value land and land having low costs and risks as high-value la...

Real estate brokers and builders do not often use geologic information despite the new land use laws that require a knowledge of the physical environment. These two groups were evaluated to determine their technical knowledge, the level of knowledge they desire, and the specific information they need from the geologist. They are not proficient in e...

The north insular shelf of Molokai is a smooth plain, gently dipping seaward, with three slight steps, one occurring between the 30- and 60-foot isobaths, one between the 150- and 180-foot isobaths, and one near the 300-foot isobath. The shelf break occurs near the 500-foot isobath. Off East Molokai Volcano the shelf is cut by eleven submarine cany...
