This 3 foot (1 meter) high AquaDam is started well up and over the railing to ensure that it will be able to fill completely. The end is tied back to lend it extra support during filling.
You can clearly see how the fill tubes come up and over the rail. The tide is out in this picture.
The AquaDam has been fully inflated and the tide is coming in.
A close-up view of where the AquaDam abuts into the concrete wall. Virtually no seepage is getting through; the ground is only damp!
The tide continues to come in.
High tide, and the beach remains high and dry. The water depth is approximately 1 feet (.5 meter). It looks like less, but remember that the beach continues to slope down, so the right side of the AquaDam is actually slightly higher than the left side.
