1.) Two 8ft tall 17ft wide 60ft long single closed end (SCE) AquaDams were successfully installed across a stream impacted by ocean tides. The installation took place during low tide. The job site was at the very far reaches of tidal influence. The work area needed to be de-watered for the construction of a water intake pipe.

2.) Each AquaDam was installed in approximately one hour. The contractor placed Geo-Blocks behind the AquaDams to help support them. During high tide this AquaDam will be maxed out and the blocks will give additional support.

3.) One AquaDam was placed upstream and the other one downstream to isolating the work area. This configuration is referred to as staggered.

4.) Geo-Blocks are being strategically positioned to provide reinforcement for the AquaDam. While additional AquaDams would have been more effective in terms of support, the limited space at this particular location necessitated an alternative approach. Therefore, rather than utilizing smaller dams to supplement the main 8ft tall AquaDams, the contractor opted to use Geo-Blocks instead.

5.) The Geo-Blocks provide a much thinner footprint. Notice that one end of the AquaDam is open on the bottom of this photo. This is the open end and fill-tubes of the 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.

6.) The Geo-Blocks were stacked here forming a support wall for the AquaDam. Excavation for the intake pipe can now take place.
