An underwater soil erosion prevention system has a generally rectangular length of material folded at regularly spaced intervals at an angle generally perpendicular to the longitudinal axis of the rectangular length of material, thereby forming sheets. Each sheet contains slits which are generally perpendicular to the fold. The slits begin above the bottom edge of the sheet and terminate below the top edge of the sheet. The sheets contain openings sized to snugly receive an anchor line on either side. To aid in deploying the soil erosion prevention system, an inflatable rollable array with a receiving valve is provided. The array can be rolled together with the underwater soil erosion prevention system, and when ready for deployment, a fluid is controllably inserted into the array through the receiving valve, thereby causing the array and system to unroll. Alternatively, the underwater soil erosion prevention system can be releasably attached to a frame mechanism to facilitate deployment underwater. |
