- By installing flow-deflecting guides which direct the flow of
water at the bends towards the centre of the river and simultane-
ously cause the creation of cooling longitudinal vortices. Viewed
along the direction of flow, these induce anti-clockwise rotating
vortices at left hand bends and clockwise vortices at right hand
bends.
The flow-guide or vortex generator (see Fig. 11.3) is made of pre-
cast concrete, its curved surface fluted with grooves running paral-
lel to the direction of flow, to prevent any lateral slip. It is triangular
in shape, the apex pointing downstream. The wider, upstream end
of the triangle is horizontal and flush with the riverbed, so as to
scoop up the onflowing water and curl it over centripetally
(inwardly spiralling) into a vortex in the centre of the channel. This
movement gathers up the suspended and dissolved growth-
enhancing substances (carbones), from near the banks and the
riverbed, allowing them to mix with the dissolved oxygen which in
all healthy streams collects in the central flow axis.
These (negatively-charged) fructigenic carbones become ener-
gized when moved centripetally and are thus able to combine with
the fertilizing (positively charged) oxygen. The oxygen is cooled by
a positive temperature gradient, resulting in a freshening and rein-
vigorating of the water. At the shallower parts of the river between
the bends, the accumulated energies from this organic synthesis
allow the discharge of nourishing salts into the groundwater in the
banks.^3 - By the implanting of 'energy-bodies' in midstream, anchored
to the river bed, which re-energize the water by forming natural lon-
gitudinal vortices. These would be used where the flow-guides are
inappropriate — in the straighter stretches of a channel for
instance — and where the removal of sediment is desirable.
Although never described by Viktor Schauberger in detail, these
could take the form of egg-shaped longitudinal vortex-generators
with neutral buoyancy achieved through small holes allowing pen-
etration of the outer water. Schauberger may have applied this prin-
ciple from observing the stationary trout.
Vortices may also be introduced by placing large (preferably met-
alliferous) boulders in the centre of the channel. Schauberger found
that the boulders that 'floated' in a very cold stream contained metal
oxides and silicates, so these stones would actually increase the - RIVERS AND HOW THEY FLOW
