Hydrogeology and simulation of ground-water flow in the thick regolith-fractured crystalline rock aquifer system of Indian Creek basin, North Carolina
Charles C. Daniel, Douglas G. Smith, Jo Leslie Eimers
1997, Water Supply Paper 2341-C
The Indian Creek Basin in the southwestern Piedmont of North Carolina is one of five type areas studied as part of the Appalachian Valleys-Piedmont Regional Aquifer-System analysis. Detailed studies of selected type areas were used to quantify ground-water flow characteristics in various conceptual hydrogeologic terranes. The conceptual hydrogeologic terranes are...
Factors influencing stream fish recovery following a large-scale disturbance
W.E. Ensign, K.N. Leftwich, P. L. Angermeier, C.A. Dolloff
1997, Transactions of the American Fisheries Society (126) 895-907
We examined fish distribution and abundance in erosional habitat units in South Fork Roanoke River, Virginia, following a fish kill by using a reachwide sampling approach for 3 species and a representative‐reach sampling approach for 10 species. Qualitative (presence–absence) and quantitative (relative abundance) estimates of distribution and...

Walden P. Pratt, editor(s)
1997, Circular 1140
The Harrison 1 deg X 2 deg quadrangle in southwestern Missouri and northwestern Arkansas and the Joplin 1 deg X 2 deg quadrangle in southeastern Kansas and southwestern Missouri were studied under the Conterminous United States Mineral-Resource Assessment Program (CUSMAP). Map publications in the CUSMAP folios included bedrock geology, subsurface...
Analysis of minimum 7-day discharges and estimation of minimum 7-day, 2-year discharges for streamflow-gaging stations in the Brazos River basin, Texas
Timothy H. Raines, William H. Asquith
1997, Water-Resources Investigations Report 97-4117
The minimum 7-day, 2-year discharge (7Q2) was estimated for each of 97 streamflow-gaging stations in the Brazos River Basin, Texas, with at least 10 years of unregulated or 10 years of regulated discharge data using the Pearson Type III distribution fitted by L-moment statistics of the annual minimum 7-day discharges....
