Hydrology of Watersheds in Lake County Area Studied

A report that documents the simulation of rainfall-runoff relations for watersheds in Lake County, Ill., with computer models has been released by the U.S. Geological Survey (USGS), U.S. Department of the Interior. The study was done in cooperation with the Lake County Stormwater Management Commission and is part of Lake County's comprehensive stormwater-management program.

USGS hydrologist Jim Duncker, coauthor of the report, said, "The results of the study provide engineers, scientists, and planners with an accurate means of analyzing current stormwater problems and the effects of future development on flooding in Lake County. The computer model which simulates the hydrology of watersheds in Lake County can be used to simulate various flow conditions and land-use planning scenarios," Duncker added. "For example, the computer model can be utilized to simulate changes in the amount of runoff generated in a watershed as a result of a planned housing development."

The report, titled "Regional Rainfall-Runoff Relations for Simulation of Streamflow for Watersheds in Lake County, Illinois," by J.J. Duncker, T.J. Vail, and C.S. Melching, is published as U.S. Geological Survey Water-Resources Investigations Report 95-4023. Copies are available for inspection at the U.S. Geological Survey, 221 N.
