Chicago Lakefront
Description
Much of the existing lakefront for the City of Chicago was created as a large landfill
project in the 1920's and 1930's. The project was protected from waves by a stepped-
stone revetment that has fallen into disrepair.
The U.S. Army Engineer District,
Issue
Chicago (LRC), requested that the CHL
conduct a physical model study to
measure overtopping rates for various
cross-sectional configurations of a
proposed stepped revetment for the
Chicago lakefront. The new revetment is
being planned as part of the Chicago
Shoreline Storm Damage Reduction
Project.
Physical model studies at a 1:38

(model:prototype) scale were conducted
in a two-dimensional wave flume
equipped with a computer-controlled

were determined by LRC based on wave
hindcasts and measured wave conditions.
