    • The Illinois Streamflow Assessment Model (ILSAM) was developed to provideneeded streamflow information to watershed managers and planners. This specialized software program was developed for use on a personal computer to provide estimates of the...
    • Streamflow Frequency Assessment for Water Resource Evaluation

    • Mackinaw River; Vermilion River; mathematical models; streamflow; watershed
    • Streamflow frequency estimates for two major watersheds, the Mackinaw and Vermilion River watersheds in the Illinois River Basin, were prepared for use with the Illinois Streamflow Assessment Model (ILSAM). ILSAM is a water resource planning and...

    • Driven by the force of gravity, water continually moves between the land surface and the subsurface environments. Our knowledge of this process is limited by the large number of interdependent factors involved. A better understanding of these...
    • Evaluation of the accuracy of radar precipitation for use in flow forecasting for the Fox Chain of...

    • 2006; Fox River (Wis. and Ill.); ISWS CR 2006-05; Precipitation (Meteorology) -\- Measurement; Precipitation forecasting; Radar meteorology; Stream; Streamflow -\- Computer simulation; Upper Fox Watershed; Watershed; Westcott, Nancy E., Vernon H....
    • This study evaluated the use of radar-derived daily precipitation values for estimating watershed precipitation in the Fox River watershed in northeastern Illinois and southeastern Wisconsin, and for the potential use in preparing real-time...
    • Hydrologic Modeling of Climate Scenarios for Two Illinois Watersheds

    • Fox River; H. Vernon Knapp; Iroquois River; Jaswinder Singh; Karla Andrew; climate; climate change; groundwater; hydrology; streamflow; watershed
    • Watershed modeling applications for the Fox and Iroquois River watersheds in Illinois were used to evaluate the response in simulated streamflow to various climate scenarios. The climate scenarios applied to both watersheds are based on simulations...
    • Hydrologic Model of the Vermilion River Watershed for Streamflow Simulations

    • Jaswinder Singh; Vermilion River; mathematical model; streamflow; watershed
    • In continuation of the efforts made by the Illinois State Water Survey to develop a detailed hydrologic and water quality simulation model of the entire Illinois River Basin, a hydrologic simulation model was developed for the Vermilion River...
    • Groundwater discharge to Illinois streams

    • Natural resources and the environment: Water resources: Rivers and streams
    • Driven by the force of gravity, water continually moves between the land surface and the subsurface environments. Our knowledge of this process is limited by the large number of interdependent factors involved. A better understanding of these...

    • Lake Decatur is the water supply reservoir for the City of Decatur. The reservoir was created in 1922 by constructing a dam to impound the flow of the Sangamon River. The dam was modified in 1956 to increase the maximum capacity of the lake to...
    • The 1988-1989 drought in Illinois: causes, dimensions, and impacts

    • 1992; Droughts; ISWS RR-121; Lamb, Peter J., ed.; Water-supply
    • 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,...
