Gabions are an important part of hydroseeding, as they protect streambanks
and slopes from the erosive forces of moving water. Rock filled mattresses or
gabion baskets can also be used retaining walls for slopes, to divert water flow
away from eroding channel sections, to armor the bank or bed of channels.
Vegetated or rock filled gabions can be used in streaming sections subject to
extreme erosion due to increased disturbance flows or during construction.
Gabion wall can be specified at places where vegetative streambank protection is
not enough, with flow rates over 6 ft/sec. Gabions can also be used to construct
groins or deflectors envisioned for diverting flow away from eroding streambank
sections, such as gabion mesh.
