If you need to create a de-watered area in which to
work but maintain some river flow Flume Pipes may be
the answer. Downstream fish farms are a typical
situation. In this picture the flume pipes have been
bridged to allow vehicular traffic flow.
How's it done?
Use 2 Aquadams to form a Flume Pipe
Sandwich. In this picture there is a 3ft Aquadam
laid underneath a mighty 8 footer.

The 3 ft dam is first stretched part way across the
river and the fluming pipes laid on top. The flume
pipes must be at least 5ft apart and the underdam
stretch at least 5ft beyond the last flume pipe.
The 8 footer is deployed in the normal way. In this
example the flume pipes are not submerged but they could
be!
When the 8ft Aquadam is fully inflated the area
around the flume pipes will leak due to "bridging".

However, when the "fill end" of the 3ft dam is
elevated and then filled to around 5% of its capacity
the bridging closes up to form a water seal around
the flume pipes.

De-watering of the working area can begin.
This is the Aquadam Flume System in place
with the river flows being taken by the
fluming pipes.
