Use of the chloride ion in determining hydrologic-basin water budgets - A 3-year case study in the San Juan Mountains, Colorado, U.S.A.
H.C. Claassen, M.M. Reddy, D.R. Halm
1986, Journal of Hydrology (85) 49-71
Measurement of chloride concentration and water equivalent in precipitation and recharge at a site can be extrapolated to determine available moisture in a nearby basin. This method also may be extrapolated to a basin with similar climatic characteristics if precipitation, vegetation, and topographic data are available. The average accuracy of...
A boundary element-Random walk model of mass transport in groundwater
M. Kemblowski
1986, Journal of Hydrology (85) 305-318
A boundary element solution to the convective mass transport in groundwater is presented. This solution produces a continuous velocity field and reduces the amount of data preparation time and bookkeeping. By combining this solution and the random walk procedure, a convective-dispersive mass transport model is obtained. This model may be...
River meanders and channel size
G. P. Williams
1986, Journal of Hydrology (88) 147-164
This study uses an enlarged data set to (1) compare measured meander geometry to that predicted by the Langbein and Leopold (1966) theory, (2) examine the frequency distribution of the ratio radius of curvature/channel width, and (3) derive 40 empirical equations (31 of which are original) involving meander and channel...
An analytical scheme for determining forms of sulphur in oil shales and associated rocks
M. L. Tuttle, M. B. Goldhaber, D.L. Williamson
1986, Talanta (33) 953-961
An analytical scheme for determining various forms of sulphur in oil shales and associated rocks is presented. Acid-soluble sulphate, sulphur contained in monosulphide and in disulphide minerals, and organically-bound sulphur are all quantitatively recovered as separate fractions. Finely-ground oil-shale samples are treated in an inert atmosphere with 6M hydrochloric acid to...

V. A. Trent
1986, Miscellaneous Field Studies Map 1887
Maps are generated by combining digital ownership data with geologic resource estimates and other spatial coal data in a geographic information system (GIS). For example, we merged the newly compiled Federal coal ownership files with resource calculations from the 1970's for the Powder River Basin (Trent, 1986). For the first...

Understanding where landslide processes in California have been most severe is helpful in determining priorities for landslide mapping, mitigation measures, and preparedness planning. Although a few studies of landslide damage and fatalities have been published (see sources of data 12, 17, 34, 36, 40), and many more reports mention landslide...

Hydrologic characteristics of soils in parts of Arkansas, Colorado, Kansas, Missouri, Nebraska, New Mexico, Oklahoma, South Dakota, and Texas
Jack T. Dugan
1986, Hydrologic Atlas 678
Certain physical characteristics of soils, including permeability, available water capacity, thickness, and topographic position, have a definite effect on the hydrology of an area. They control the rate at which precipitation infiltrates or is transmitted through the soil, and thus they have a significant role in determining the rates both...
Irrigated acreage and other land uses on the Snake River Plain, Idaho and eastern Oregon
Gerald F. Lindholm, S. A. Goodell
1986, Hydrologic Atlas 691
Prompted by the need for a current, accurate, and repeatable delineation of irrigated acreage on the Snake River Plain, the U.S. Geological Survey entered into a cooperative agreement with the Idaho Department of Water Resources Image Analysis Facility and the U.S. Bureau of Reclamation to delineate 1980 land use form...
