AquaDam®
The second method for moving the AquaDam® is to slide the entire dam. The resistance to sliding is provided by the friction between the ground and the structure. Although any type of barrier could slide along the ground if the pushing force were great enough, we will present the calculations for sliding the AquaDam® in order to quantify its tendency to slide.
AquaDam®
In addition to the variables already defined we add:
µ=coefficient of friction between AquaDam® and its supporting surface
f=friction force
N=normal force (equivalent to weight)
Assumptions:
We are assuming that the supporting surface is smooth and flat. Any deviation from a smooth surface will add greater opposition to sliding. Again, we assume that the inner tubes are generally rectangular to facilitate the calculations.
