US 5,348,419 A · System for erosion control

Abstract

A method and apparatus for ascertaining and implementing the permeability effective for preventing and repairing scour or erosion in a control zone associated with a river or shoreline having a bank and a bed associated with a moving fluid. The method provides for preventing and repairing scour or erosion in a control zone associated with a river or shoreline having a bank and a bed associated with a moving fluid. Associated therewith, a variably permeable jetty system (Palisade.TM. system) is provided for preventing and repairing scour or erosion in a control zone associated with a river or shoreline having a bank and a bed associated with a moving fluid.

Claims21

Dependent claims

A system for preventing and repairing scour or erosion in a control zone associated with a river or shoreline having a bank and a bed associated with a moving fluid, said apparatus comprising:

(a) spatial property measuring means for determining one or more spatial properties of the river or shoreline;
(b) physical parameter measuring means for determining one or more physical parameters of the river or shoreline;
and
(c) permeator means for controlling the moving fluid prior to contacting the bank in the control zone such that said permeator means employs the spatial property determinations and the physical parameter determinations for eliciting one or more permeability effective for preventing and repairing scour or erosion in the control zone associated with the river or shoreline.

1 more element

A system for preventing and repairing scour or erosion in a control zone associated with a river or shoreline having a bank and a bed associated with a moving fluid, said apparatus comprising:

(a) a plurality of corresponding variably permeable diffusers of generally rectangular configuration to be erected in spurs in the control zone to extend inwardly into the moving fluid from the bank to be protected at spaced intervals along the length of the bank, each variably permeable diffuser having two opposed ends with connecting formations along its ends;
(b) a plurality of connecting collars to be connected to upper and lower corner zones of the variably permeable diffusers, the collars being adapted to be slidably located over appropriately positioned pilings to slidably connect the variably permeable diffusers between pairs of spaced pilings for readily sagging on the pilings during use;
and
(c) a plurality of elongated support members to be connected along the ends of the variably permeable diffusers by means of the connecting formations to extend between the upper and lower regions of the variably permeable diffusers during use for maintaining them in an upright condition with the lower regions resting on the river bed for following the contours thereof when scouring occurs.
