Approximate altitude of water levels in wells completed in the Chicot and Evangeline aquifers in the Houston area, Texas, January-February 1991
This report is one in a series of reports that annually depict altitudes of water levels since 1977, the most recent of which (Barbie and others, 1991) presented maps of the altitudes of water levels for 1990. This report was prepared in cooperation with the City of Houston and the Harris-Galveston Coastal Subsidence District, and preents approximate altitudes of water levels in wells in the Chic

Approximate altitude of water levels in wells completed in the Chicot and Evangeline aquifers in Fort Bend County and adjacent areas, Texas, January-February 1991
This report was prepared in cooperation with the Fort Bend Subsidence District, and presents maps of the approximate altitude of water levels in wells completed in the Chicot and Evangeline aquifers (figs. -2) during January-February 1991 in Fort Bend County and adjacent areas, Texas. These approximate altitudes of water levels give an approximate depth to potable ground water within Fort Bend Co

Approximate changes in water levels in wells completed in the Chicot and Evangeline aquifers, 1990-93 and 1992-93, in Fort Bend County and adjacent areas, Texas
This report was prepared in cooperation with the Fort Bend Subsidence District and presents data on water-level changes in wells during 1990-93 and 1992-93 in the Chicot and Evangeline aquifers (figs. 1-4) in Fort Bend County. Water-level changes maps were prepared previously by Locke (1990), and Locke and Santos (1992) for both aquifers, and by Wesselman (1972) for the Chicot aquifers.

Approximate changes in water levels in wells completed in the Chicot and Evangeline aquifers, 1977-93 and 1992-93, and measured compaction, 1973-92, in the Houston-Galveston region, Texas
This report is one in a series of reports that depict water-level changes since 1977 and compaction of subsurface material since 1973. The report was prepared in cooperation with the Harris-Galveston Coastal Subsidence District and the City of Houston, and presents maps showing the approximate changes in water levels in wells completed in the Chicot and Evangeline aquifers, 1977-93 and 1992-93 (f

Habitat suitability index model for brook trout in streams of the Southern Blue Ridge Province: Surrogate variables, model evaluation, and suggested improvements
Data from several sources were collated and analyzed by correlation, regression, and principal components analysis to define surrrogate variables for use in the brook trout (Salvelinus fontinalis) habitat suitability index (HSI) model, and to evaluate the applicability of the model for assessing habitat in high elevation streams of the southern Blue Ridge Province (SBRP). In all data sets examined

Flood discharges in the upper Mississippi River basin, 1993
From mid-June through early August 1993, flooding was severe in the upper Mississippi River Basin following a wet-weather pattern that persisted over the area for at least 6 months before the flood. The magnitude and timing of several intense rainstorms in late June and July, combined with wet antecedent climatic conditions, were the principal causes of the flooding.
Flood-peak discharges that equ

Sediment characteristics of North Carolina streams, 1970-79
Data collected at 152 sampling sites during 1970-79 were used to characterize fluvial sediment in North Carolina streams. On the basis of predominant land use in individual basins, sites were categorized into one of five groups: forested (7 sites), forested and affected by minor development (7 sites), rural affected by agriculture (83 sites), rural affected by nonagricultural activities (38 sites)

Low-flow characteristics of streams in North Carolina
Ten low-flow hydrologic areas were defined for North Carolina by relating topography, geology, mean annual runoff, and other features to low-flow frequency characteristics for 122 continuous-record streamflow stations and 396 partial-record streamflow stations. Regression equations relating low-flow characteristics to mean annual discharge were developed for five of the hydrologic areas covering 4
