Floodgate removal led to dike failure

To The Eagle:

It is quite clear that, prior to the removal of the two floodgates on the lower Kandoll Road, and their replacement with two 13 foot diameter culverts, the Seal Slough Dikes were quite stable, and had been so for decades. It doesn't take a rocket scientist (actually, a Fluvial Geomorphologist!) to determine that the flow of tidewaters back and forth, through the culverts, is affecting the dikes.

Rather than do a complex three dimensional incompressible fluid flow analysis of the river and the slough to prove what is self evident, it will be much cheaper for CLT and Ducks Unlimited to simply remove the culverts.
