Floods of July 18-20, 1996, in northern Illinois Floods of July 18-20, 1996, in northern Illinois
Record flooding occurred on many streams in northern Ilinois during July 18-20, 1996. Over 16 inches of rain fell at some locations during and just prior to this period. Peak of record discharges were recorded at 19 U.S. Geological Survey (USGS) streamflow-gaging stations. The USGS, in cooperation with the Illinois Department of Natural Resources, Office of Water Resources (IDNROWR), has...

Composite recovery type curves in normalized time from Theis' exact solution Composite recovery type curves in normalized time from Theis' exact solution
Type curves derived from Theis’ exact nonequilibrium well function solution are proposed for graphical estimation of aquifer hydraulic properties, transmissivity (T), and storage coefficient (S), from water‐level recovery data after cessation of a constant‐rate discharge test. Drawdown (on log scale) is plotted versus the ratio of time since pumping stopped to duration of pumping, a...

Sediment transport in the lower Missouri and the central Mississippi rivers, June 26 through September 14, 1993 Sediment transport in the lower Missouri and the central Mississippi rivers, June 26 through September 14, 1993
Sediment data were collected for five sediment stations on the lower Missouri and the central Mississippi rivers during the 1993 flood. During the period of June 26 to September 14, 1993, 55 million metric tons was transported past St. Louis, Missouri by the Mississippi River. Sediment was stored in the Missouri River floodplain above the Mississippi River as more than 22,000 hectares of

Direct simulation of groundwater age Direct simulation of groundwater age
A new method is proposed to simulate groundwater age directly, by use of an advection-dispersion transport equation with a distributed zero-order source of unit (1) strength, corresponding to the rate of aging. The dependent variable in the governing equation is the mean age, a mass-weighted average age. The governing equation is derived from residence-time-distribution concepts for the...

Development, verification, and application of a simplified method to estimate total-streambed scour at bridge sites in Illinois Development, verification, and application of a simplified method to estimate total-streambed scour at bridge sites in Illinois
A simplified method to estimate total-streambed scour was developed for application to bridges in the State of Illinois. Scour envelope curves, developed as empirical relations between calculated total scour and bridge-site chracteristics for 213 State highway bridges in Illinois, are used in the method to estimate the 500-year flood scour. These 213 bridges, geographically distributed...

Hydraulic, geotechnical, geomorphic, and biologic data for the Cache River/Heron Pond area in southern Illinois Hydraulic, geotechnical, geomorphic, and biologic data for the Cache River/Heron Pond area in southern Illinois
Heron Pond, located in extreme southern Illinois, lies immediately adjacent to the upper Cache River. The upper Cache River is encroaching on Heron Pond, which has raised the issue of the possibility of a failure of the Heron Pond wall, the area between Heron Pond and the upper Cache River. Hydraulic, geotechnical, geomorphic, and biologic data were collected by the U.S. Geological...
