Seven AquaDams, each measuring 4ft in height, 9ft in width, and 100ft in length, were strategically placed within the Mad River in Arcata, California to redirect the flow of water.

The AquaDam, utilized as a cofferdam, facilitated the retrofitting of bridge pier abutments and the containment of dredge spoils.

The AquaDams effectively redirected the flow of the river while also preventing dredge and sediment discharge materials from entering the waterway.

Here we can see two AquaDam cofferdam systems that were installed in horseshoe/”U” shape configurations at the bridge abutments.

The AquaDams effectively redirected the flow of the river water, allowing for containment of the contaminated water within the designated work areas.

Non-abrasive fill material can be placed alongside an AquaDam to offer extra support. Take note of the pristine water quality surrounding the AquaDam.

On the left, we observe murky water, while on the right, we see clear water.

AquaDams are constructed using lightweight and flexible materials, allowing them to be easily turned.

This “V” shaped configuration was able to divert the flow of the river off of the area workers needed to dig.

Great work, everyone!
