Several AquaDams were installed by workers from the California Department of Transportation in Oakland, California to assess the dams' response to waves and tidal influences.
The AquaDam in the foreground is secured in place by round-edged boulders that have been strategically placed on top of a protective material covering the AquaDam.
Looking towards the starting bank for this single closed end (SCE) AquaDam. To ensure proper installation and functionality of a SCE AquaDam, it is essential to have a starting bank that maintains a higher elevation than the body of the AquaDam. The open end and fill-tubes of the SCE AquaDam must remain elevated above the full height of the dam along its designated path. It is important to note that an AquaDam will only reach its maximum height at the lowest elevation point along its designated path.
The SCE AquaDam, surrounded by a boulder system, appears to be holding up well as the tide rises.
A worker stepped out onto the SCE AquaDam as the water levels continued to rise. The fully inflated AquaDam provides a stable and secure platform for workers to stand on.
The SCE AquaDam is currently functioning in water depths that surpass its design specifications. Nevertheless, both the workers and the AquaDam remain unharmed in these demanding conditions.
The water depth has overcome the height of the AquaDam. AquaDams are constructed using lightweight and flexible materials, allowing them to float when empty in deep enough water. An AquaDam will float in water depths greater than its filled height, but the AquaDam in this photo must have had material laid over it prior to the boulder placement.
The entire body of the SCE AquaDam is now underwater.
It appears that this set of AquaDams has washed out. Unlike the SCE AquaDam seen previously, this set did not have the additional material and weight system to keep them in place.
Some water remained inside this AquaDam at its closed end.
This section of dam was completely moved from its origin.
