Abstract
The Busse Woods Drop Structure and recreation area is located in
Cook County, Illinois in Suburban Chicago. Operated as a typical Soil
Conservation Service drop structure since 1976, it is now contemplated that
the structure be modified to reduce flood flows downstream of the structure
for floods greater than the two-year event. In order to maintain its present
low flow capabilities and at the same time decrease the return frequency for
high discharges associated with low frequency return interval events, it was
proposed by the illinois Department of Transportation (IDOT) that a 2.3 ft
high steel box beam be installed 1.2 feet above the crest. Placement of
such a beam would modify the existing weir flow into three flow regimes:
1) weir flow at low flows, 2) orifice flow at moderate flows, and 3) a
combination of orifice and weir flow when the beam is overtopped at higher
flows. This report contains the results of rating curve and sediment erosion
tests carried out on a 1:12 geometric scale hydraulic model of half of the
structure.
