A wave barrier for protecting users and their possessions at a beach location close to the water from becoming wet from waves crashing into their location. The wave barrier includes a flexible wall sheet with a plurality of spaced apart elongate poles coupled thereto. The lower ends of the poles are downwardly extended from a bottom edge of the wall sheet. The proximal edge of a ground sheet is coupled to the wall sheet along the bottom edge of the wall sheet.
A method for packaging conventional silt fencing and a product produced by the method. Silt fabric is attached to a number of evenly spaced stakes. The stakes are then bunched together so that the silt fabric hangs between the stakes in descending loops. The bunching is continued until all the stakes lie close together in one plane. The loops of silt fabric are then wrapped tightly around the stakes. Securing bands are then placed around the assembly to create a flat pack.
A method of protecting and improving the quality of water in a body of water which comprises identifying areas of water runoff and/or points of storm water entrance into the body of water and the provision of floating booms to separate a small area(s) of a reservoir where surface and storm water run-off from the water shed or storm water entrance points enter the main body of water. Supported from the booms is a filter curtain of geosynthetic fabric material which is anchored to the floor of the reservoir along the profile of the reservoir floor. The fabric material has small openings in sufficient number to permit passage of a predetermined volume of water per unit time, but small enough to block particulate biodegradable organic particulate matter. The run off or storm discharge contains particulate matter, which is a carrier of microorganisms as small as one micron. The filter curtain prevents passage of the particulate matter and non-organic turbidity causing particles. This greatly concentrates the particulate organic subject matter and provides a concentrated source of nourishment for microorganisms. The microorganisms or bacteria consume and decompose the biodegradable particulate matter thus improving the quality of the run-off or discharge as it passes the filter curtain and enters the main body of water. The microorganisms consume and biodegrade the organic material trapped by the fabric sheet and ultimately perish as the biodegradable organic material is consumed. The results in substantially lowering coliform count and the biodegradable organic matter in the main body of water. The invention is also applicable to the entrance points of streams or brooks which receives surface water run-off and feed into the body of water to be protected.
A rapid emergency dam is disclosed. During adverse weather conditions heavy rain can lead to rivers breaking their banks and lakes overflowing causing flooding to the surrounding countryside. Coastline defenses can also be breached by increased sea swell and large waves. A fluid barrier section (1) of the present invention comprises an elongate rectangular fluid barrier sheet 2, an apron 4 extending from the lowermost edge 6 of the fluid barrier (2), an elongate rectangular front panel (7) and support means in the form of a plurality of support ribs (8). The fluid barrier sheet (2) is of a flexible fluid impermeable material such as plastics, rubber, waterproof canvas, nylons or any other suitable natural or man made material. A preferred material for the barrier sheet (2) is a fluid impermeable tear resistant flexible foil. In one preferred embodiment of the present invention the lowermost edge (6) of the fluid barrier is bonded to one edge of the apron (4). The bond provides a fluid impermeable joint between the apron 4 and the fluid barrier sheet (2) when erected.
