| Looking at the previous table, the value of the coefficient of friction would allow the dam to slide on a smooth flat surface. Coefficients of friction in the range 0.10 to 0.25 are appropriate for quiet slippery surfaces, for example greasy plate steel, railway wheels. In most cases, the surface under the AquaDam® will be comparatively rough and will have a far greater coefficient of friction with the AquaDam®, and hence will pose even greater opposition to sliding. The principles used to create AquaDams® are simple yet effective. The stable non-rolling wall of water conforms to the surface beneath it creating a tight seal. An AquaDam® will not tip or move even if the water level raises to the top of the structure. AquaDams® provide a lightweight, reusable and environmentally friendly method of water control.
