Abstract
A sediment control barrier, comprising a ground contacting surface having a length suitable for controlling fluid flow across ground, barrier material extending perpendicularly from the ground contacting surface, means for securing the ground contacting surface to the ground; and the barrier material being structured to conform to a ground contour. A sediment control barrier is proposed that has slots to enable flexing of the barrier material. Another sediment control barrier is proposed having a graded permeability from a first, lower, non-zero permeability adjacent the ground contacting surface to a second, higher, permeability away from the ground contacting surface.

A sediment control barrier, comprising:
- a ground contacting surface having a length suitable for controlling fluid flow on a sloped surface having a profile;
- barrier material extending perpendicularly from the ground contacting surface to a distal edge;
- means for securing the ground contacting surface to the ground;

- and
- the ground contacting surface being deformable upon lengthwise compression of the barrier material to conform to the profile of the sloped surface.
