Stated Goals
 Prevent the headcutting at the battlefield
location
 Limit maximum flood elevation to preproject conditions
 Control velocity upstream to manage
scour along the riverbanks
BUILDING STRONG®
Design
 The structure was designed to stop headcutting and control flood elevations
upstream to pre-project conditions which
in turn aided in managing scour at the
battlefield location and along the
riverbanks by controlling velocity.
BUILDING STRONG®
Externalities
 Construction of the grade control structure would
affect the channel upstream of this project and
create pre-project conditions, i.e., flooding in areas
that had not experienced flooding since the channel
project began would now be flooded again.

The Value Ah Ha!
Functions
 The current flood levels
can be maintained to limit
maximum flood elevation to
below pre-project
100%
conditions
 Grade controls can be
distributed along the river
rather than at a concrete
waterfall
