		Title:	100 - year rainstorms in the Midwest: design characteristics
		Volume/Number:	1993
		Issuing Agency:
		Description:	This document provides pertinent information on the spatial distribution characteristics of extremely heavy rainstorm events in Illinois and the Midwest. Relations were developed for those storms in which maximum rainfall at the center equaled or exceeded the point maximum experienced on the average of once in 100 years or longer. The study was limited to this group of storms because of existing needs for information on these extreme storm events in the design and operation of water control structures in small basins. It is recommended for use in conjunction with Illinois State Water Survey Bulletin 70, Bulletin 71 (Midwestern Climate Center Research Report 92-03), and Water Survey Circular 173 for runoff computations related to the design and operation of runoff control structures in small basins subject to extreme rainfall events. Area-depth relations were derived from information obtained through operation of several dense raingage networks, detailed field surveys and analyses of severe rainstorms in Illinois, analyses of heavy rainstorms in a six-basin hydroclimatic study, and exceptional storms recorded by the climate network of the National Weather Service in Illinois. Using data and information from these sources, curves defining spatial distributions for storms of various areal extent were derived. Results are presented in a form readily adaptable for use by hydrologists or other interested users.

		Title:	The 1980-1981 drought in Illinois: causes, dimensions, and impacts
		Volume/Number:	1982
		Issuing Agency:
		Description:	This report addresses the 1980-1981 drought in Illinois. This 15-month drought, which began in February 1980 and was centered in the southern portions of the state, was not one of the extreme droughts of record. However, its importance derives from the fact that it is the most severe drought since those of the early 1950s. As such, the 1980-1981 drought potentially reflects a new set (or new types) of impacts on the states water resources due to many technological, hydrological, and institutional changes since the 1950s.As noted above, droughts are a basic and important feature of the climate and water resources of Illinois. The interesting near absence of droughts in the state between 1955 and 1976 makes the drought of 1980-1981 of great interest, although it was not extremely severe.

		Title:	The 1988-1989 drought in Illinois: causes, dimensions, and impacts
		Volume/Number:	1992
		Issuing Agency:
		Description:	The 1988-1989 drought was one of the most disastrous droughts in the history of the state. Hydrologic, meteorological, and climatological aspects of the 1988-1989 drought in Illinois are addressed. The drought is evaluated in terms of recipitation, streamflow, lakes and reservoirs, and ground-water resources of the state. The meteorological conditions that produced the drought also are addressed. Impacts and problems resulting from the drought are discussed along with various actions taken to ameliorate the problems. Although the primary goal of the study was to quantify the drought, primarily in a physical sense, an important secondary goal was to assess the impacts and the actions employed in order to derive information needed in future planning and handling of Illinois droughts. The report thus ends with a set of recommendations for coping with future droughts.

		Title:	The 1993 flood on the Mississippi River in Illinois
		Volume/Number:	1994
		Issuing Agency:
		Description:	This report on the 1993 flood on the Mississippi River in Illinois and on the lower reaches of the Illinois River was prepared by the Illinois State Water Survey with assistance from the Illinois Department of Transportation/Division of Water Resources and the Illinois Natural History Survey. The report begins with a brief description of the physical setting of the Upper Mississippi River System, including historical facts on climate, precipitation, hydrology, and floods. The 1993 flood is discussed with regard to precipitation, soil moisture, stages, flows, levee breaches, and discharge through levee breaches. Also discussed are impacts of the flood on social, economic, hydraulic and hydrologic, and environmental aspects of the river and its residents. Impacts on water quality, the environment, and public water supplies, including the beneficial and detrimental aspects of the flood, also are included. The lessons learned from this flood focus on the performance of the levees, governmental responses, the effects of flood fighting, change in stages due to levee breaches, flood modeling, and the lack of information dissemination to the public on the technical aspects of the flood. These lessons point out information gaps and the need for research in the areas of hydraulics and hydrology, meteorology, sediment transport and sedimentation, surface and groundwater interactions, water quality, and levees. The report presents a comprehensive summary of the 1993 flood as far as climate, hydrology, and hydraulics are concerned.

		Title:	The 2005 Illinois drought.
		Volume/Number:	2006
		Issuing Agency:
		Description:	Dry conditions in 2005 reached a historic level of severity in some parts of Illinois and ranked as one of the three most severe droughts in Illinois in 112 years of record. The timing of the dryness during the spring and summer, when water demand and use are high, ensured substantial impacts on agriculture and other sectors. The drought also had several unusual characteristics. The drought area was long and narrow, extending from south Texas to the Great Lakes, but within the Midwest, the drought had relatively minor impacts on states other than Illinois. A record number of remnants of hurricanes and tropical storms passed through Illinois during July, August, and September, substantially ameliorating drought conditions in portions of central and southern Illinois. Crop yields were surprisingly high in parts of the state, perhaps providing evidence of increased drought resistance in modern varieties and the benefits of timely rains.

		Title:	Atmospheric dispersion study of deicing salt applied to roads : first progress report
		Volume/Number:	2000
		Issuing Agency:
		Description:	This report describes the status of an initial effort to understand and describe the atmospheric transport of road salt in the form of sodium chloride (NaCl) applied to highways as a deicing material. The study area is a proposed 20.1 kilometer or km (12.5 mile) tollway that is planned to extend Interstate 355 (I-355) located west of Chicago, Illinois, to connect Interstate 55 (I-55) and Interstate 80 (I-80) southwest of Chicago near Lemont, Illinois. Prior to construction, which has not yet begun, the focus of the effort has been to establish background levels of the road salt aerosol, to construct permanent sites along the proposed route corridor from which to better monitor and measure road salt aerosol properties, and to identify important parameters for use in constructing a computer model to describe the salt emission and deposition. The present status of the proposed project is that construction plans have been delayed at least until approval of a supplement to the environmental impact statement. Results from chemical analysis of aerosol and snow samples are reported that show progress toward characterizing the road salt aerosol with respect to its size, mechanisms of emission, range of atmospheric transport, and mechanisms of deposition. Analysis of the preliminary data suggest: 1. A large portion of the salt aerosol that becomes aerosolized is emitted after the road surface has been cleared of snow and ice. 2. Approximately 90 percent of the airborne road salt is contained in aerosol particles of diameter larger than 2.5 micrometers or 10^-4 inches. 3. The salt deposition pattern near a treated roadway as determined by snow samples decreases consistently with distance from the road. Average deposition values for a single snow event are found here to yield an aerial deposition of 0.06 grams per square meter (0.6 pounds per acre) at 500 meters (1,640 feet) from the road. The corresponding value for the total deposition per length of roadway is 85 grams per meter or g/m (300 pounds per mile or lb/mi). Five permanent sampling sites are almost completed and will provide a flexible monitoring capability to better quantify the road salt emission, transport, and deposition. Road salt emissions in aerosol samples collected at the locations of two of the permanent sites are reported here. The sites are located 0.6 km (0.4 mi) and 1.0 km (0.6 mi) southeast of I-55 in the prevailing downwind direction, but could also be affected by salt emission from a secondary road in the vicinity. A comparison of the aerosol measurements at the two sampling sites during periods when salt was applied shows that the site nearer to the sources consistently had higher levels of NaCl. Most of the NaCl was found in particles with diameter larger than 10 micrometers (4x10^-4 inches).

		Title:	Bank erosion survey of the Illinois River : volume 2 : appendices
		Volume/Number:	2000
		Issuing Agency:
		Description:	This report summarizes the research and surveying that were conducted in 1995 to determine the amount and severity of bank erosion that existed on the entire length of the Illinois River. The study reach extended from Grafton, River Mile (RM) 0 to Joliet, RM 286. A multi-disciplinary team of scientists traveled the entire length of the river, mapped bank conditions and erosion sites, and selected 29 reaches for detailed data collection and two sites as observation sites. Bank erosion types were developed by studying and analyzing the erosion features. The team also used fluvial and bank failure processes to guide detailed data collection at the 29 sites. Color-coded bank feature maps were developed for the entire 286 miles of the river.

		Title:	Bank erosion survey of the main stem of the Kankakee River in Illinois and Indiana.
		Volume/Number:	2001
		Issuing Agency:
		Description:	This report is the second of a series of three reports being prepared for the work done on the Kankakee River based on a Conservation 2000 Grant from the Illinois Department of Natural Resources. The present report focuses on the bank erosion mapping of the main stem of the Kankakee River from Route 30 Bridge in Indiana to the mouth of the Kankakee River with the Illinois River near Wilmington. A total of 111.8 river miles were mapped during a boat trip November 19-December 1, 1998. The relative magnitude of erosion was based on a visual assessment of the river banks during a boat trip along the main stem of the river. No actual measurements were taken. However, the extent of erosion was noted on 7.5-minute quadrangle maps based on visual observations. A series of 27 maps has been developed in which bank erosion identified on both sides of the river ranged form minor to high erosion. This analysis has shown the 10.4 river bank miles had severe erosion, 39.4 bank miles had moderate erosion, 70.8 bank miles had minor erosion, 46.3 bank miles were stable, 46.7 river bank miles were artificially protected, and data on 10.0 bank miles could not be collected because snags, islands, etc. made the banks inaccessible. This is a first attempt to map existing bank erosion conditions of the main stem of the Kankakee River.

		Title:	Benchmark sedimentation survey of the lower Cache River wetlands.
		Volume/Number:	2001
		Issuing Agency:
		Description:	The Cache River located in the southernmost part of Illinois flows through an area containing the Cache River Wetlands. These unique and important wetlands were designated as a Ramsar Site in 1996. Drainage activities divided the Cache River in half in the early 1900s, effectively separating the river into the Upper and Lower Cache Rivers. The Lower Cache River contains a remnant of a vast wetland system called the Lower Cache River State Natural Area (LCRSNA), commonly referred to as Buttonland Swamp. Sediment inflow from several tributary streams has an impact on the wetland. Previous research has determined that 217,000 tons of sediment were deposited in Buttonland Swamp between 1986 and 1988. The wetlands of the Lower Cache River have been targeted for preservation and restoration by state, federal, and private environmental organizations. A program to monitor the sediment deposition rate within the wetland area at regular intervals would be useful in evaluating and guiding preservation and restoration efforts. This project established a benchmark measure of the deposition rates and cross-sectional profiles at selected locations in the LCRSNA wetland.
