Inflatable rubber dams are cylindrical rubber fabrics placed across channels, and streams and act as a weir or dam to raise the upstream water level when inflated. The membrane is a multi-layer fabric made of synthetic fibre (usually nylon) and rubberised on one or both sides. The fabric is flexible and yet exhibits good wear-resistance ...
Spill containment is where spills of chemicals, oils, sewage etc. are contained within a barrier or drainage system rather than being absorbed at the surface. One method is to use an inflatable stopper or pneumatic bladder which is inserted into the outflow of a drainage system to create a containment vessel.
The Fence and Pipe flow device needs very little maintenance and limits where and how high the beavers can dam; however, to be most effective, the intake end of the pipe should usually sit in at least 3 feet (91 cm) of water. When this water depth is not possible, a simple Culvert Protective Fence may be the best option.

Erosion control is the practice of preventing or controlling wind or water erosion in agriculture, land development, coastal areas, river banks and construction.

h is the height of the water column in metres. A = area = rectangle: length × height measured in m 2 where: length = the horizontal length of a rectangular floodgate measured in metres height = the height of a non-submerged flood gate from the bottom of the water column to the water surface measured in metres
