A water-quality assessment of the Jordan Creek watershed, Warren County, Indiana

A water-quality assessment of the Jordan Creek watershed was made September 24 and 25, 1974. Surface waters within the watershed were calcium bicarbonate types with very similar concentrations of major dissolved constituents and specific conductance values. Streamwaters contained less than 0.26 milligram per litre dissolved nitrate (as N), 0.03 milligram per litre or less dissolved phosphate (as P

A water-quality assessment of the Rock Creek (Cass) watershed, Cass and Carroll counties, Indiana

A water-quality assessment of the Rock Creek (Cass) watershed was made June 12 and 13, 1974. Nutrients were resampled November 7, 1974. Surface waters within the watershed were calcium bicarbonate types with very similar concentrations of major dissolved constituents. Samples collected June 13 contained between 7.4 and 14 milligrams per litre dissolved nitrate (as N), between 0.05 and 1.3 milligra

Water quality of hydrologic bench marks; an indicator of water quality in the natural environment

Water-quality data, collected at 57 hydrologic bench-mark stations in 37 States, allow the definition of water quality in the 'natural' environment and the comparison of 'natural' water quality with water quality of major streams draining similar water-resources regions. Results indicate that water quality in the 'natural' environment is generally very good. Streams draining hydrologic bench-mark

Water demands for expanding energy development

Water is used in producing energy for mining and reclamation of mined lands, onsite processing, transportation, refining, and conversion of fuels to other forms of energy. In the East, South, Midwest, and along the seacoasts, most water problems are related to pollution rather than to water supply. West of about the 100th meridian, however, runoff is generally less than potential diversions, and e

Floods in Indiana: technical manual for estimating their magnitude and frequency

This manual provides methods for estimating the magnitude and frequency of floods on unregulated and unurbanized streams in Indiana that drain at least 15 square miles (38.8 square kilometres). The methods provide the design engineer with a means of estimating flood frequencies without having to analyze the records at individual streamflow sites. The estimating equations in this manual are based o
