Abstract
Coastal stabilization with multiple flow control of water to and from foraminous pipes and adjacent subsoil. Offshore underwater subsoil is fluidized by injection of water via underlying foraminous piping, thereby increasing the concentration of subsoil suspended in the overlying water during its onrush onto the shore. Under normal conditions beach subsoil is dewatered by withdrawing water therefrom via adjacent foraminous piping, and under stormy conditions subsoil further onshore is dewatered via foraminous piping adjacent thereto, inducing deposition of the suspended subsoil onto the adjacent land. Water collected by such dewatering can be stored temporarily and be discharged by use in such fluidization or be discharged to the sea.
Claims16
Coastal stabilization apparatus, comprising a substantially horizontal array of foraminous-walled piping means at or below the subsoil surface, including one such piping means at about maximum storm runup onshore as viewed in plan, each piping means in the array being oriented generally parallel to the shoreline, being adapted to interchange water via its foraminous wall openings with adjacent non-cohesive subsoil, being interconnected via valved non-foraminous piping means, and connected to pumping means whereby the respective foraminous means are adapted to dewater or to fluidize subsoil adjacent thereto and at least one such piping means offshore adapted to interchange water with the adjacent body of water via an interconnected valved inlet/outlet pipe directed further offshore.
Coastal stabilization apparatus, convertible between a normal mode of operation useful during good weather and an emergency mode of operation useful during stormy weather, comprising
- an array of substantially horizontal and substantially parallel lengths of buried foraminous piping, including at or below the prevailng water
- at least one such piping length underlying beach land,
- at least one such piping length underlying an onshore location at about furthest storm runup, and
- at least one such piping length underlying an offshore location;
- piping directly interconnecting the aforesaid piping lengths,
- flow-control valves at respective piping junctions, and
- pumping means adapted to provide water interchange into or out from respective foraminous piping lengths from or into adjacent subsoil.
Coastal stabilization method, convertible between a normal mode of operation useful during good weather and an emergency mode of operation useful during stormy weather, comprising steps of establishing an array of water-interchange sites buried in non-cohesive subsoil, including a plurality of substantially horizontal parallel linear arrays of such sites, at or below the prevailing water level, at least one such linear array underlying beach land, at least one such linear array underlying an onshore location at about furthest storm runup, and at least one such linear array underlying an offshore location, and comprising also operational steps of providing and controlling water interchange into and out from the respective foraminous linear arrays from or into adjacent subsoil.
