Recommendations

Info

Wherever the water body is not subject to tidal and/or wind and wave action, the curtain should extend the entire depth of the water and rest on (or be anchored to) the bottom. Failure to maintain contact with the bottom will allow sediment to move under the curtain. It is recommended that the height of the curtain be 20% greater than the depth of the water to allow for fluctuations. Wherever the water body is subject to significant tide, wind, or wave action, the weighted bottom of the curtain should not extend to the bottom of the water body. Wind and wave action can cause the bottom of the curtain to move along the bottom, stirring up sediment. Therefore, a minimum 1-foot gap should be provided between the bottom of the curtain and the bottom of the water body at mean low water. Curtain heights beyond 12 feet are generally not practical. Curtains installed deeper than this are subject to very large loads with consequent strain on curtain materials and the anchoring system. The overall length of the curtain should be 10 - 20% greater than the straight-line measurement of the perimeter to facilitate installation and reduce stress caused by wind and/or waves. Both ends of the curtain should be securely anchored to the shoreline. An excessive number of joints should be avoided. A minimum continuous span of 50 feet between joints is recommended. For stability purposes, the maximum span between joints should be 100 feet. For applications where it is desirable for water to pass through the curtain (e.g. when used instead of a baffle in a sediment basin), a curtain with one or more panels of screen fabric should be used. In this application, the curtain may remain in place over winter months. Installation - Follow the manufacturer’s guidelines for proper installation. Make sure all obstacles, impediments, and potentially damaging objects have been removed from the installation area prior to beginning the installation. Figures 3.14 through 3.17 illustrate typical installations. However, manufacturer’s details should be used for actual installation.
