AQUADAM® HEIGHT SELECTION AND SIZE CRITERIA

AquaDam® height selection is determined by work site conditions, the water depth to be contained or diverted, and to a lesser degree, stream bed slope and water velocity. Maximum projected changes in water depth are very important during the life of the diversion project. Table 1 lists sizes of AquaDams® and their recommended water depth usage. Customized dams of any length can be ordered.

This chart represents maximum water depths to be controlled on flat surfaces. The slope and topography of the streambed needs to be accounted for as well as water depths.

 

Water Depth:

The height of water to be contained by the AquaDam® is the most important factor when selecting the proper size. A good rule of thumb for determining the water height after diversion is as follows: 

Add:
1.) the maximum water depth along the installation site, 

2.)the average depth of water at the installation site, 

3.) and the difference in elevation (water levels) between the installation and diverted water sites. 

These three numbers equal the height of water that will be found at the installation site after the AquaDams® have been installed and water is flowing through the diversion channel. 

The importance of determining the correct projected maximum water depths after installation and diversion of the stream cannot be taken too lightly. Too small of an AquaDam® will fail.  The depth of water to be retained by an AquaDam® is often underestimated, resulting in an AquaDam® that is too small for the project. This results in delays, increased costs and potentially unsafe work conditions!
