Abstract

The water, sediment and erosion control apparatus of the present invention includes a water-permeable foam barrier extending generally longitudinal. The barrier has an upstream surface and a downstream surface. The apparatus also includes an apron extending laterally away from at least one surface of the barrier. The apparatus is reconfigurable for different applications by rotating the barrier relative to the apron. The method of the present invention comprises providing a reusable apparatus having an angled barrier and a protective apron, and anchoring the apparatus generally perpendicular to a natural flow of water, such that the water carrying the sediment is slowed and sediment is deposited upstream of the apparatus.

Claims

1. An apparatus for controlling water, sediment and soil erosion comprising:

a water-permeable foam barrier extending generally longitudinally, said barrier having an upstream surface and a downstream surface; and

an apron extending laterally away from at least one of said surfaces of said barrier, said barrier attached to said apron by attaching means wherein said barrier is reconfigurable by rotating said barrier about a longitudinal axis of said attaching means.

2. The apparatus of claim 1 wherein said barrier includes a triangular-shaped cross section.

3. The apparatus of claim 2 wherein said upstream surface and said downstream surface form an approximate 90°

angle at an apex of said barrier.

4. The apparatus of claim 1 wherein said barrier further comprises a base surface, said base surface forming an approximate 90°

angle with said downstream surface.

5. The apparatus of claim 1 wherein said apron is disposed about said barrier.

6. The apparatus of claim 1 wherein said apron extends laterally away from both said upstream surface and away from said downstream surface of said barrier.

7. The apparatus of claim 1 wherein said apron is formed from a single piece of water-permeable material.

8. The apparatus of claim 1 further comprising means for anchoring the apparatus to a ground surface.

9. An apparatus for controlling water, sediment and soil erosion comprising:

a longitudinally extending barrier having an upstream surface and a downstream surface;

a protective apron disposed about said barrier, said protective apron having an approach apron portion extending in a lateral direction from said upstream surface and an exit apron portion extending in a lateral direction from said downstream surface; and

a longitudinal attaching means for providing an axis about which said barrier is reconfigurable by rotating said barrier relative to said apron.

10. The apparatus of claim 9 wherein said barrier includes a triangular-shaped cross section.

11. The apparatus of claim 10 wherein said upstream surface and said downstream surface form an approximate 90°

angle at an apex of said barrier.

12. The apparatus of claim 9 wherein said barrier further comprises a base, said base forming an approximate 90°

angle with said downstream surface.

13. The apparatus of claim 9 wherein said barrier is formed of a water-permeable foam material.

14. The apparatus of claim 9 wherein said apron is formed from a single piece of water-permeable material.

15. The apparatus of claim 9 further comprising means for anchoring the apparatus to a ground surface.

16. The apparatus of claim 9 wherein said attaching means includes a seam about which said barrier is selectively pivotable between first and second positions.

17. A method of controlling water, sediment and soil erosion comprising:

providing a reusable, collapsible apparatus having a barrier and a protective apron, said barrier comprising an angled upstream surface shaped such that the water carrying the sediment exerts a force on said barrier perpendicular to a ground surface; and

anchoring the apparatus to said ground surface generally perpendicular to a natural flow of the water carrying the sediment, such that the water carrying the sediment is slowed, allowing sediment to be deposited upstream of the apparatus.

18. The method of claim 17 further comprising:

providing the barrier with a 90°

triangular cross section; and

orienting the barrier relative to the protective apron such that the 90°

angle of the barrier is adjacent a drop inlet, whereby each apparatus may be perpendicularly abutted to other apparatus such that the abutted apparatus form a dike around the drop inlet to reduce the amount of sediment which enters the drop inlet.

19. A method of controlling water comprising:

providing an apparatus having an angled barrier, a protective apron and means for preventing water from passing through the barrier; and

anchoring the apparatus generally perpendicular to a flow of water, whereby water is prevented from passing through the barrier and must reach a higher level to flow over the barrier.

20. The method of claim 19 further comprising:

providing the barrier with a 90°

angle; and

orienting the barrier relative to the apron such that the 90°

angle is opposite an angled face of the barrier which confronts the water.

21. An apparatus for controlling water, sediment and soil erosion comprising:

a water-permeable foam barrier extending generally longitudinally, said barrier having an upstream surface and a downstream surface;

an apron extending laterally away from at least one of said surfaces of said barrier; and

means for preventing fluid from passing through said barrier.

22. The apparatus of claim 21 wherein said means comprises a water-impermeable member disposed between said apron and said downstream surface.

23. An apparatus for controlling water, sediment and soil erosion comprising:

a water-permeable foam barrier extending generally longitudinally, said barrier having an upstream surface and a downstream surface;

an apron extending laterally away from at least one of said surfaces of said barrier; and

means for reducing a height of said barrier to a lower elevation than a base portion of ends of said barrier such that the water flows over the apparatus at a predetermined location.

24. An apparatus for controlling water, sediment and soil erosion comprising:

a longitudinally extending barrier having an upstream surface and a downstream surface;

a protective apron disposed about said barrier, said protective apron having an approach apron portion extending in a lateral direction from said upstream surface and an exit apron portion extending in a lateral direction from said downstream surface;

a longitudinal attaching means for providing an axis about which said barrier is reconfigurable by rotating said barrier relative to said apron; and

means for preventing fluid from passing through said barrier.

25. The apparatus of claim 24 wherein said means for preventing fluid comprises a water-impermeable member disposed between said apron and said downstream surface.

26. An apparatus for controlling water, sediment and soil erosion comprising:

a longitudinally extending barrier having an upstream surface and a downstream surface;

a protective apron disposed about said barrier, said protective apron having an approach apron portion extending in a lateral direction from said upstream surface and an exit apron portion extending in a lateral direction from said downstream surface;

a longitudinal attaching means for providing an axis about which said barrier is reconfigurable by rotating said barrier relative to said apron; and

means for reducing a height of said barrier to a lower elevation than a base portion of ends of said barrier such that the water flows over a reduced height portion of said barrier rather than around an end of said barrier.

27. A method of controlling water, sediment and soil erosion comprising:

providing a reusable apparatus having an angled barrier and a protective apron;

anchoring the apparatus generally perpendicular to a natural flow of the water carrying the sediment, such that the water carrying the sediment is slowed, allowing sediment to be deposited upstream of the apparatus; and

positioning the apparatus in an open drainage ditch such that a base portion of each end of the barrier is higher in elevation than a lowest point of an apex of the barrier, whereby the water will flow over the apex at a predetermined location rather than around the end of the barrier, thus preventing erosion around the ends of the barrier.
