Hydrologic and chemical interaction of the Arkansas River and the Equus Beds aquifer between Hutchinson and Wichita, south-central Kansas
N. C. Myers, G.D. Hargadine, Joe B. Gillespie
1996, Water-Resources Investigations Report 95-4191
Large chloride concentrations in Arkansas River water have the potential to degrade water quality in the adjacent Equus beds aquifer between Hutchinson and Wichita, Kansas. The aquifer is an important source of water for municipal, industrial, agricultural, and domestic uses.

1996, Water-Resources Investigations Report 95-4188
Ground-water resources are the only source of water in most of the San Juan structural basin and are mainly used for municipal, industrial, domestic, and stock purposes. Industrial use increased dramatically during the late 1970's and early 1980's because of increased exploration and development of uranium and coal resources....

Comparison of estimated and observed stormwater runoff for fifteen watersheds in west-central Florida, using five common design techniques
J.T. Trommer, J.E. Loper, K.M. Hammett, Georgia Bowman
1996, Open-File Report 96-129
Hydrologists use several traditional techniques for estimating peak discharges and runoff volumes from ungaged watersheds. However, applying these techniques to watersheds in west-central Florida requires that empirical relationships be extrapolated beyond tested ranges. As a result there is some uncertainty as to their accuracy. Sixty-six storms in 15 west-central Florida...
