Modified level II streambed-scour analysis for structure I-70-69-5185 crossing East Fork White Lick Creek in Hendricks County, Indiana
B.A. Robinson, D. C. Voelker, R. L. Miller
1997, Open-File Report 97-309
Level II scour evaluations follow a process in which hydrologic, hydraulic, and sediment transport data are evaluated to calculate the depth of scour that may result when a given discharge is routed through a bridge opening. The results of the modified Level II analysis for structure 1-70-69-5185 on Interstate 70...

1997, Open-File Report 97-250
The U.S. Geological Survey collected hydrologic data at 12 continuous-record stations along the Colorado River and its major tributaries between Glen Canyon Dam and Diamond Creek. The data were collected from October 1989 through September 1995 as part of the Bureau of Reclamation's Glen Canyon Environmental Studies. The data include...
User's guide for MODTOOLS: Computer programs for translating data of MODFLOW and MODPATH into geographic information system files
Leonard L. Orzol
1997, Open-File Report 97-240
MODTOOLS is a set of computer programs for translating data of the ground-water model, MODFLOW, and the particle-tracker, MODPATH, into a Geographic Information System (GIS). MODTOOLS translates data into a GIS software called ARC/INFO. MODFLOW is the recognized name for the U.S. Geological Survey Modular Three-Dimensional Finite-Difference Ground-Water Model. MODTOOLS...

Water levels in, extent of freshwater in, and water withdrawal from eight major confined aquifers, New Jersey Coastal Plain, 1993
Pierre J. Lacombe, Robert Rosman
1997, Water-Resources Investigations Report 96-4206
Water levels in 722 wells in the Coastal Plain of New Jersey, Pennsylvania, and northeastern Delaware were measured during October and November 1993 and were used to define the potentiometric surface of the eight major confined aquifers of the area. Isochlors (lines of equal chloride concentration) for 250 and 10,000...
Methods for estimating magnitude and frequency of floods in the southwestern United States
Blakemore E. Thomas, H. W. Hjalmarson, Scott D. Waltemeyer
1997, Water Supply Paper 2433
Methods were developed for estimating magnitude and frequency of floods at gaged and ungaged sites in the Southwestern United States. Estimating equations for ungaged sites were developed by transferring information from gaged to ungaged sites using multiple regression and a hybrid method developed during this study. The methods and analysis...
Impacts of volcanic gases on climate, the environment, and people
Kenneth A. McGee, Michael P. Doukas, Richard Kessler, Terrence M. Gerlach
1997, Open-File Report 97-262
Gases from volcanoes give rise to numerous impacts on climate, the environment, and people. U.S. Geological Survey (USGS) scientists are inventorying gas emissions at many of the almost 70 active volcanoes in the United States. This effort helps build a better understanding of the dynamic processes at work on the...
Quality of shallow ground water in alluvial aquifers of the Willamette Basin, Oregon, 1993-95
Stephen R. Hinkle
1997, Water-Resources Investigations Report 97-4082-B
The current (1993?95) quality of shallow ground water (generally, <25 meters below land surface) in Willamette Basin alluvium is described using results from two studies. A Study-Unit Survey, or regional assessment of shallow groundwater quality in alluvium, was done from June through August 1993. During the Study-Unit Survey, data were...
