Complex High-Rise Foundation Design and Construction
The substructure design and construction of a 60 story office tower in downtown Chicago is described. The presence of existing belled caissons on hardpan required use of filtered dewatering...
Conversion of Mixed Waste to LSA Waste?A Case Study
This paper describes a treatment process that was successfully employed at the National Guard Armory in Chicago, Illinois, to convert sludge classified as hazardous chemical/radioactive...
Irrigation and Aquifer Management in Illinois
The ground-water resources in eastern Kankakee and northern Iroquois Counties, Illinois, have been used for irrigation for over 50 years. During the drought of 1988, 131 irrigation wells...
Agricultural, Meteorologic, and Hydrologic Drought Relations: Applications to Irrigation and Water Supply Planning
Meteorologic and hydrologic factors can combine to significantly reduce crop yields, leading to an agricultural drought. Agricultural and hydrologic droughts affect a large segment of...
Estimating Impacts of Irrigation on Streamflow
This paper presents a method for estimating the impact of irrigation withdrawals on streamflows and shows the application of that method to the Kankakee River Basin of Illinois and Indiana....
Channel Entrenchment Along the Post Creek Cutoff in Southern Illinois
The Post Creek Cutoff was constructed in 1915 by the Cache River Drainage Commission to divert flow from the Upper Cache River to the Ohio River. The construction of the cutoff reduced...
Bank Failure and Erosion on the Illinois Waterway
In 1988, bank failure and erosion on the Illinois Waterway were evaluated. Banks were inspected from the air and from a motor vessel; thirty-one sites were examined in detail. Severe erosion...
Soil Erosion, Sediment Yield, and Deposition in the Illinois River Basin
The amount of soil erosion of the Illinois River Basin was estimated by using the 1982 National Resources Inventory (NRI) and the Illinois Geographic Information System (GIS). The sediment...
Measuring Resuspension of Sediment by Barge Tows
An earlier effort to measure resuspension of sediment relied on U.S. standard depth-integrating sediment samplers. In designing a new effort to collect field data on resuspension, the...
Identifying Temporal Change in the Spatial Correlation of Regional Groundwater Contamination
An approach for estimating the semivariogram based on the jackknife method can be used in connection with standard confidence procedures to set closely approximate confidence limits on...
Modeling Variations in Soil Moisture and Streamflow Resulting from Climatic and Land Use Changes
A distributed parameter watershed model IWASCH has been developed to simulate variation in soil moisture and baseflow conditions for agricultural areas in Illinois, resulting from climatic...
The Illinois GIS and Hydrologic Database
Development of the Illinois Geographic Information System (GIS) from 1983 to the present is described including the hardware configuration and ARC/INFO software. The database design at...
Advanced Reconstruction for Subsidence-Damaged Homes
To address many of the residential damage-reconstruction problems from mine subsidence a research and development project was undertaken in Illinois. Phase I of this project is complete...
Burlington Cable-Stayed Bridge
The Burlington cable-stayed bridge will carry US34 over the Mississippi River from Burlington, Iowa to Gulfport, Illinois. There will be two 12-ft lanes in each direction plus an acceleration...
Quincy Bayview Bridge?Construction Control
A cable-stayed bridge crossing the Mississippi River at Quincy, Illinois, was completed in August 1987. The structure includes twin concrete towers and a hybrid deck section. The cable...
Sewer Rehabilitation?Metro Chicago
After a number of public hearings in the late 1960's and early 1970's which focused on sewer backup problems in the Sanitary District's separate...
Hydrologic and Hydraulic Calibration?A Case Study (a)
The Addison Creek watershed is in Cook and DuPage Counties just west of Chicago, Illinois. Because the watershed has a history of major flooding, eight major stormwater and flood control...
Vacuum Sewers: Fundamentals and Design Methods
Vacuum sewer (VS) systems have important advantages over conventional gravity sanitary sewers or septic tank-soil absorption systems when one or more of the following conditions hold:...
Hydrologic Conditions at the Des Plaines Wetlands
An area of abandoned farmland and gravel quarries in northeastern Illinois has been converted to a test site for methods to reestablish or restore wetlands. Four stream gaging stations...
Hydraulic Study for the Construction of Artificial Islands in Peoria Lake, Illinois
Long-term sediment accumulation in the lake reduced the average depth of the lake from 8 feet in 1903 to 2.6 feet in 1985, which resulted in the deterioration of aquatic habitats and recreational...
