Are there any limitations related to the slope of the stream bank or stream bed gradient?
If the slope is parallel to the length of the AquaDam, it does not have an affect on the stability of the structure as long as the depth of the containment does not exceed the recommended values along that length. The ideal installation site for an AquaDam would be a smooth flat surface, but it will also provide a stable retention system on mild stream bed gradients. If the stream bed gradient becomes more extreme, backing the AquaDam with gravel, dirt, or an additional AquaDam will prevent sliding or rolling. If the only available installation site has a significant bed gradient, the best solution is to use a larger AquaDam to provide additional head above the contained water.
