Technique for estimating the 2- to 500-year flood discharges on unregulated streams in rural Missouri
A generalized least-squares regression technique was used to relate the 2- to 500-year flood discharges from 278 selected streamflow-gaging stations to statistically significant basin characteristics. The regression relations (estimating equations) were defined for three hydrologic regions (I, II, and III) in rural Missouri. Ordinary least-squares regression analyses indicate that drainage area (R

Flood of 1993—Mississippi River near the Jefferson National Expansion Memorial (Arch), St. Louis, Missouri
River-flow data have been collected on the Mississippi River at St. Louis near the Jefferson National Expansion Memorial (Arch) since 1861. Water at this location is excess river flow from 13 States and part of Canada (drainage area of about 697,000 square miles). Many disaster conditions, including floods and droughts, have affected this area; however, the flood of 1993 will be remembered not onl

Reversal of declining ground-water levels in the Chicago area
Abundant water resources have been an important part of the economic development of the Chicago area for more than a century. The city of Chicago, Ill., and other lakefront towns have used Lake Michigan as a water supply. Where water from Lake Michigan was not available or a need for supplemental water supplies was present, deep wells (generally greater than 700 feet) provided a clean, reliable, a

Hydrogeology and water quality of the Mississippi River alluvium near Muscatine, Iowa, June 1992 through June 1994
A study of the Mississippi River alluvium near Muscatine, Iowa, was conducted to evaluate ground-water flow and water quality using data collected from June 1992 through June 1994. The study area included approximately 80 square miles in parts of Muscatine and Louisa Counties in Iowa and Rock Island and Mercer Counties in Illinois.
A steady-state, ground-water flow model was constructed using Febr

Potential-scour assessments and estimates of maximum scour at selected bridges in Iowa
The results of potential-scour assessments at 130 bridges and estimates of maximum scour at 10 bridges in Iowa are presented. All of the bridges evaluated in the study are constructed bridges (not culverts) that are sites of active or discontinued streamflow-gaging stations and peak-stage measurement sites. The period of the study was from October 1991 to September 1994.
The potential-scour assess

Urban stormwater runoff study at Davenport, Iowa
Urban storm water runoff is being investigated as a nonpoint source of pollution across the country as urban areas with populations over 100,000 conduct studies designed to meet U.S. Environmental Protection Agency guidelines for National Pollutant Discharge Elimination System permits for their stormwater discharges. From 1991 through 1994, the City of Davenport, Iowa (fig. 1), and the U.S. Geolog

Delineation of flooding within the upper Mississippi River basin — Flood of July 30, 1993, in Jefferson City and vicinity, Missouri
This report provides Missouri River flood-peak elevation data and delineates the areal extent of flooding in Jefferson City and vicinity, Missouri, for July 30, 1993. The July 1993 flood is compared with the Federal Emergency Management Agency's (FEMA) 100- and 500-year flood profiles. This report is one of a series of U.S. Geological Survey reports to document the flooding within the upper Missis

Delineation of flooding within the upper Mississippi River Basin, 1993 — Flood of June 29-September 18, 1993, in Iowa City and vicinity, Iowa
The hydrologic investigations atlas shows the areas in and around Iowa City, Iowa, that were flooded by the Iowa River in 1993. This map also depicts the Federal Emergency Management Agency (FEMA) 100-year flood boundaries. The drainage basin of the Iowa River at Iowa City received well over 100 percent of normal rainfall in June, July, and August, 1993. At the Cedar Rapids airport, located about

Contraction scour at a bridge over Wolf Creek, Iowa
Contraction scour at the State Highway 14 bridge over Wolf Creek in south-central Iowa was caused by a large flood on September 14 and 15, 1992. The bridge is a 30.5-m, single-span steel structure supported by vertical-wall concrete abutments with wingwalls. Approximately 6 meters of scour resulted from the flood. The peak discharge was estimated by water-surface profile analysis to be 2,200 cubic

Relation between stream-water quality and geohydrology during base-flow conditions, Roberts creek watershed, Clayton County, Iowa
An investigation to determine the relation between stream water quality and geohydrology in the Roberts Creek watershed, Clayton County, Iowa, was conducted during selected base-flow periods in 1988-90. Discharge measurements were made and water samples collected for analyses of nutrients and selected herbicides in 19 subbasins along the main stem and tributaries of Roberts Creek. The areal extent
