Storm Event Flow and Sediment Simulations in
Agricultural Watersheds using DWSM
- DWSM, the dynamic watershed simulation model, was expanded with a subsurface and a reservoir flow routing
schemes. The hydrology and sediment components of the model were applied to three agricultural watersheds in Illinois, Big
Ditch (100 km2), Court Creek (250 km2), and Upper Sangamon River (2,400 km2) ...

Comparison of mercury in atmospheric deposition and in Illinois and USA soils
- It has been reported that most mercury (Hg) in USA soils is from atmospheric Hg deposition, mostly from anthropogenic
sources. This paper compares the rates of atmospheric Hg deposition to amounts of Hg in Illinois and USA soils. The amounts of Hg in these soils are too
great to be attributed mainly to anthropogenic atmospheric Hg deposition.

Potential Toxicity of Metals and Ammonia in Peoria Lake Sediments and Pore Water
- The concentrations and potential toxicity of several heavy metals (cadmium (Cd), copper (Cu),
nickel (Ni), lead (Pb), and zinc (Zn)) and ammonia in sediments and pore waters of Peoria Lake to 30 cm
depth have been characterized.

Arsenic Geochemistry and Distribution in the Mahomet Aquifer
- "Arsenic Geochemistry and Distribution in the Mahomet Aquifer" presents the results of a detailed study of
arsenic in Tazewell and Champaign Counties. It includes spatial and depth distributions, speciation (the chemical forms of arsenic),
and ther relationship between arsenic and other dissolved substances.

Flow dimensions corresponding to hydrogeologic conditions
- We show that a radial flow system with a linear, constant-head boundary asymptotically reaches a flow
dimension of four, while the flow dimension of a leaky aquifer is a function of time and
the leakage factor. We use numerical techniques to show that a stationary transmissivity
field with a modest level of heterogeneity has a flow dimension that stabilizes at two.

Water, Sediment, Nutrient, and Pesticide
Measurements in an Agricultural Watershed
in Illinois During Storm Events - Flow and concentrations of suspended sediment, nitrate-N, phosphate-P, atrazine, and metolachlor were
monitored during the spring seasons of 1998 and 1999, primarily during storm events, at a tributary station (Big Ditch) and
two main-stem stations (Fisher and Mahomet) of the Upper Sangamon River watershed in east central Illinois. These three
stations respectively drain 98, 622, and 932 km2 of mainly agricultural lands.

Effects of Future Precipitation Increases on the Hydrologic Cycle
of an Illinois Basin - A key question raised by the increases in precipitation occurring during latter half of the 20th Century over Illinois and the central U.S. concerned the potential effects on the
hydrologic cycle. Projections of climate change for the Midwest call for these rain increases to continue into the future, and this study sought to estimate how all
components of the hydrologic cycle of a typical Illinois basin would be affected.

Involvement of Atmospheric Sciences in Illinois Policy Issues, 1950-2001 -
Since the 1950s atmospheric scientists at the Illinois State Water Survey played proactive and reactive roles in major Illinois policy issues. Review of the 50 years of policy interactions
reveals that five factors were important for obtaining successful science-policy interactions.

Quantification of Climate Conditions Important to the Tall Grass Prairie -
The geologic history of the tall grass prairie in central North America reveals the prairie began developing 10,000 years ago after the Pleistocene ice sheets had retreated into
Canada. Long climatic records, which were not available for use in earlier studies, have allowed quantification of the climate factors that helped shape
the Midwest's tall grass prairie.
