Six methods were used to estimate the magnitude and frequency of floods at Pochack Creek at the down- stream end of the culvert on United States Route 130 and at a second site about 1,600 feet upstream at Pennsauken Township, New Jersey. Flood magnitude and frequency calculated by the six methods, as well as drainage-basin characteristics, are included in this report. The 100-year-flood estimates for the culvert site range from 280 cubic feet per second to 2,600 cubic feet per second. The 100-year-flood estimates for the upstream site range from 216 cubic feet per second to 1,800 cubic feet per second. Flood magni- tude and frequency estimates obtained by using the New Jersey Department of Environmental Protection...
Hydrogeology of the Silurian and Devonian carbonate-rock aquifer system in the Midwestern Basins and Arches Region of Indiana, Ohio, Michigan, and Illinois
Depositional framework and regional correlation of pre-Carboniferous metacarbonate rocks of the Snowden Mountain area, central Brooks Range, Northern Alaska
This report describes lithofacies, conodont biostratigraphy and biofacies, and depositional environments of Proterozoic(?) through Devonian metacarbonate rocks in the Snowden Mountain area. These rocks are correlated with successions on the Seward Peninsula and across the Brooks Range. Lithologic and paleobiogeographic data suggest that these successions formed along a single continental margin which had faunal exchange with both North America and Siberia, rather than on a series of discrete platforms juxtaposed by later tectonic events.
Physical, chemical, and biological characteristics of Pueblo Reservoir are described on the basis of data collected from spring 1985 through fall 1989. Also included are discussions of water quality of the upper Arkansas River Basin and the reservoir as they relate to reservoir operations. Pueblo Reservoir is a multipurpose, main-stem reservoir on the Arkansas River about 6 miles west of Pueblo, Colorado. At the top of its conservation pool, the reservoir is more than 9 miles long and ranges in depth from a few feet at the inflow to about 155 feet at the dam. Pueblo Reservoir derives most of its contents from the Arkansas River, which comprises native and transmountain flow. With respect to water temperature, the...
Calibration, verification, and use of a water-quality model to simulate effects of discharging treated wastewater to the Red River of the North at Fargo, North Dakota
A 30.8-mile reach of the Red River of the North receives treated wastewater from plants at Fargo, North Dakota, and Moorhead, Minnesota, and streamflows from the Sheyenne River. A one-dimensional, steady-state, stream water-quality model, the Enhanced Stream Water Quality Model (QUAL2E), was calibrated and verified for summer streamflow conditions to simulate some of the biochemical processes that result from discharging treated wastewater into this reach of the river.Data obtained to define the river's transport conditions are measurements of channel geometry, streamflow, traveltime, specific conductance, and temperature. Data obtained to define the river's water-quality conditions are measurements of concentrations...
