Application of Geographic Information System for Hydrologic Investigation
The Illinois Department of Energy and Natural Resources is developing a geographic information system (GIS) under the federally funded Lands Unsuitable for Mining Program (LUMP). This...
Suspended Sediment Transport from Nonpoint Sources
Precipitation, runoff, and suspended sediment concentration data were collected in a predominantly agricultural watershed in southwestern Illinois from January 1982 through October 1984....
Analyzing Combined Sewer Overflow Events
The Illinois Environmental Protection Agency/Illinois Pollution Control Board (ILEPA/IPCB) direct that combined sewer system overflows (CSO) be given sufficient treatment including 'first...
The Role of Hydraulics and Sediment in Large River Ecology
The National Science Foundation has sponsored a project under the long term ecological research (LTER) program which is called the 'Illinois Rivers' LTER project....
Lake Water Level and Sediment Management?Case Studies in Illinois
Estimation of the sedimentation in the lake is based on the soil erosion rates in the watershed, the sediment transport in the stream system, and lake trap efficiency. Erosion rates are...
Assessment of Sediment Problems in Peoria Lake, Illinois
Peoria Lake, located on the Illinois River in Illinois, is the deepest lake in the river valley. Since 1903, the lake has experienced approximately a 31% loss of original storage capacity...
Hydraulic Study Requirements for Bulb Type Hydropower Units at a Navigation Lock and Dam
A replacement Lock and Dam at Alton, Illinois on the Mississippi River is presently under construction. This paper presents the results of studies performed for adding six bulb type hydropower...
Unique Utilization of a Physical Model to Develop a Construction Sequence of a Major Cofferdam
Lock and Dam 26 Replacement is being constructed on the Mississippi River about 2 miles downstream of the existing Locks and Dam No. 26 at Alton, Illinois. This paper discusses the unique...
Computer Techniques for Acquisition and Reduction of Cross-Section Data
DuPage County, Illinois, has initiated a county-wide stormwater management program for planning and flood mitigation purposes. Field data with horizontal and vertical control are obtained...
Near Real-Time Climatic Data in Illinois
The need for making real-time climatic data available for use was recognized in Illinois, and a concerted effort began in 1983 to develop a system for collecting and disseminating near...
A People Mover for O'Hare International Airport
The paper addresses the considerations explored and the final plan identified as the most acceptable solution for implementation of an automated people mover at the Chicago-O'Hare...
Chicago's TARP Challenge?8 Million Tons of Rock
The Metropolitan Sanitary District of Greater Chicago (MSDGC) serves 122 municipalities covering 866 square miles in Cook County, Illinois. Of these cities, towns and villages, 53 have...
New Analysis Techniques for Structural Masonry
These seven papers on analysis of structural masonry that constitute this Proceedings were presented at a technical session at the ASCE Structural Engineering Congress held at Hyatt Regency...
Tunneling Operations and Equipment
The papers included in the Proceedings describe four diverse tunneling prjects of varying diameters, design criteria, ground conditions and construction techniques undertaken at locations...
Educator Named Chicago Civil Engineer of the Year
Strip Mine Reclamation Using Dredged Material
This alternative was investigated through the creation of a field study to demonstrate the feasibility of using a cover of dewatered dredged material to reclaim surface mine deposits....
Influence of Roughness on Velocity and Dispersion at Low Flow
Dependence of the hydraulic and transport characteristics of low flow on channel roughness is investigated. Empirical expressions are used to estimate roughness coefficient as a function...
Predicting Ground-Water Drainage to Surface Mines
A two-dimensional, finite-difference numerical model is used to simulate the drainage of ground water into a surface coal mine. Graphs of dimensionless head as a function of dimensionless...
Increased Reservoir Cost to Meet Instream Flow Needs
Low flow criteria need to be developed for determining the suitability of various low flow regimens for fish and wildlife. For choosing a desirable low flow release, the decision maker...
River Basin Management: Role of Hydraulics and Hydrology
One of the major Illinois rivers originates in a neighboring state. The main stem of the river was channelized about 65 years ago, and is considered to be a 'drainage ditch....
