The base (floor) for the Innovative Flood-Fighting Structures (IFFS) to be tested will
be constructed in the area shown in Attachment 1. Each IFFS structure will be
configured as an approximately 30 ft-long levee with two additional 10 ft- long levees
at each end of, and at right angles to, the 30 ft long levee. The two 10 ft long levees
will perpendicularly abut the concrete wing walls of the testing section. The IFFS will
be constructed to between two and 3.75 foot high.
The IFFS base must fit within the construction base area. Additional membranes
used for seepage reduction and an occasional sandbags used as membrane hold-
downs may be used in the pool area simulating the floodwater side of the IFFS. No
IFFS structure parts, sandbags or membranes will be allowed inside the "off-limit"
area shown in Attachment 1.
Structures will be subjected to hydrostatic loads from incrementally increasing
floodwater head, or depth.
Structures will be subjected to hydrodynamic loads by applying waves of
incrementally increasing height.
Structures will be subjected to steady-state overtopping at 100% of IFFS height plus 1
inch or less, as governed by the maximum pumping capacity available to recirculate
the overtopping water into the test basin.
Structures will be subjected to a prototypical impact log test.
Measurements of seepage and movement of IFFS will be made during all phases of
the testing.
Observations of movement of IFFS, fatigue or structural deterioration will be made
during all phases of the testing.
Up to three relatively small-scale repairs of documented damage are allowed during a
test series.
5.0 Constructability Evaluation
Vendors will construct and install their own product at the ERDC test facility in
Vicksburg, MS. The construction process will be recorded using a video camera. These
tapes may be used later as part of Corps flood-fight training material. The first evaluation
