The first single closed end (SCE) AquaDam has been launched from its starting bank and is being filled with water from the canal. 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.

As water is pumped into the AquaDam, the pressure from the water inside the fill-tubes pushes against the roll end, causing it to slowly unroll.

The first SCE AquaDam has almost made it to it’s ending bank.

The first SCE AquaDam continues to fill and build head as it crosses the canal.

Workers take care to ensure that the AquaDam meets the bank at a square angle for the best seal.

The first SCE AquaDam has successfully reached the opposite bank of the canal and is now ready to complete the filling process.

After an AquaDam has head above the surrounding water level, workers can utilize the body of the dam to walk on and secure ropes to. This allows for efficient and safe installation of the AquaDam.

The second SCE AquaDam has been launched and is being filled with water now. This unit will be a support for the first SCE AquaDam.

The second SCE AquaDam has almost completely unrolled and needs to finish being filled with water.

Workers have moved downstream to the next location where a set of AquaDams to be installed. All four AquaDams were installed in a staggered configuration, with one set upstream and the other downstream.

The third SCE AquaDam is almost across the canal.

The third SCE AquaDam is installed and full. This unit will also have a support AquaDam, but the support will be installed on the upstream side of the main AquaDam.

Workers install the fourth and last SCE AquaDam. It is important to install the support AquaDam right up against the main unit.

The second set of AquaDams have been filly installed. Notice how the AquaDam appears to been thinner in width in the middle of the canal, this is because that is the deepest point where the dam has been laid. In shallower water depth the AquaDam will be slightly wider.

The workers have completed their tasks, and it is now time to remove the AquaDams. The first step is to re-water the de-watered area. Following this, suction hoses are inserted into the fill-tubes of the AquaDams to drain the water from inside the dams.

The excavator helped push the fill-tubes and open end of the AquaDam down the bank so that the AquaDam could drain.

The closed end had a wooden beam attached to it and workers began to re-roll the AquaDam from that end.

The rolled up closed end (on a beam) was then drug up on shore while the water in the fill-tubes drained back into the canal. The AquaDam was then laid out on the bank and re-rolled to remove off site.

One down and three more to go.

The re-rolled AquaDams are re-secured with lifting ropes for heavy equipment to load them on a trailer.

The bucket of the excavator is pushing the open end and fill-tubes down the bank, so that the dam will drain out all of the water inside of it.

After the AquaDam has lost head above the surrounding water, the unit becomes flaccid and floats. AquaDams are constructed using lightweight and flexible materials, allowing them to float when empty in deep enough water.

Straps were secured around the closed end of the AquaDam and the dam was pulled out of the canal.

A wooden beam was attached to the closed end and the unit was re-rolled for removal.

The excavator has pushed the open end and fill-tubes of the last AquaDam down the bank, so that the unit can be drained.

As the AquaDam is emptied of water, it loses its rigidity, starts to float, and could potentially drift downstream if not properly anchored.

Here we can see the suction hoses (green) from the pumps have been inserted into the fill-tubes for draining the AquaDam.

The current from the canal pushed the mostly empty AquaDam downstream. Luckily the unit got trapped by the bridge pier.

Workers secured a rope around the closed end and pulled the unit out of the canal. Fantastic job AquaDam!
