What skills are required for installation? Is training necessary?
No particular skills are required. However, basic training is recommended. Installation is simple but does
require a minimum of understanding. Chances are you will nd everything you need to know in this manual.
If you have any questions after going through it, a technician will be happy to give you more information.
Can the Water-Gate system open up fast enough to stop waves?
The Water-Gate will open at the same speed as that of any
waves coming in. This means that regardless of the speed of the
oncoming water, the Water-Gate will open up like a parachute
does in the wind. However, if a wave has white caps on top of it,
the surplus of water will go over the Water-Gate and will need
to be pumped. To contain all types of waves, Water-Gate must
remain open; There are small holes at the base and at the top
of the partitions in which stiff rods can be inserted to keep the
barrier open at all times. A pool noodle oat can also be looped
into the Water-Gate to keep the upper edge oating.
If the ood is a mudow, and huge rocks get dragged down, will the Water-Gate withstand
the ood?
Yes, the water barrier can withstand the
pressure from a mudow. The Water-Gate
is at least three times stronger than required.
Given the fact that the density of thick mud
is approximately 1.65, the safety margin
is excellent.
As far as the presence of
large rocks is concerned,
at the beginning, there
is more water than mud
and there are no rocks.
Medium size rocks are
typically found upstream
and larger rocks are even further upstream.
Based on our expertise, we know that the
barrier will rst ll up with relatively thin
mud. Medium size rocks will arrive next. The larger rocks will only be found at the end and will never reach
the Water-Gate. Because of this, a mudow will not compromise the safety of the Water-Gate.
If the Water-Gate is left for several months or even several years in a stream, will it stay in place
during that period?
Yes, the Water-Gate will stay in place provided the water level is not much higher than the top of the
Water-Gate. Do not forget that the ow of a stream never remains the same due to alternate periods of
drought and abundant rainfall. Also, in northern areas, the water barrier can be moved by moving ice.
Observation: If the Water-Gate remains in a stream for a month or longer, a light coat of silt will form inside,
on the fabric at the bottom of the immersed Water-Gate. After four months, only 50% of the fabric will
remain visible due to the thickness of the silt.
