Deriving a term for the coefficient of friction yields:

   For current AquaDam® designs, the coefficient of friction (µ) that will allow sliding (when the water depth is equal to the height of the AquaDam®) are as follows:

   The coefficient of friction that will allow sliding if the recommended maximum waterdepths are observed is as follows:

   Coefficients of friction ranging from .10 - .20 indicate that the surface may be quite slippery. For example, the coefficient of friction between two pieces of greased or oiled steel is .10 - .20. Again we have assumed that the surface under the AquaDam® will be comparatively rough and will pose even greater opposition to sliding than indicated in the calculations above. The principles used to create the AquaDam® are simple, yet effective. The stable non-rolling wall of water conforms to the surface beneath it, creating a tight seal. The AquaDam® will remain stationary even if water levels reach the maximum recommended water containment depth. AquaDams® provide a lightweight, reusable and ecologically safe method of temporary water control.
