Wooden stake or rebar Riparian zone Stream Riparian zone Nylon cord Fig. 1B. Enlargement of the upstream block in the riparian zone showing the attachment of 2 cotton strips to the stake via a nylon cord. The distance between the stake and the first cotton strip, and the distance between cotton strips, should be approximately 25 cm. Upstream Block Cotton- strip Flow Cable binder Approx 30 cm Downstream Block Flow 25 cm 25 cm Water-surface Elevation And Fig 1C, a perspective illustrating that 1) the wooden stake/rebar are hammered well into the stream sediment, 2) the rope is tied to the base of the stake at the stream water-sediment interface, and 3) a small rock is placed on the rope immediately upstream of the cotton strip. Fig. 1A. Schematic diagram showing the deployment of cotton strips at a site. 4 strips total in each stream and each riparian zone will be deployed , and distributed between 2 blocks: one upstream, and one downstream. The approximate distance from the riparian stakes to the streams stakes will be 5 m.
Photo 1. Use a sharp object (in this case, my wife’s knitting needle) to make a hole between the threads towards one end of the strip (about 0.5 cm). Photo 3. Close the cable binder through a loop that was tied to the rope (above photo). Two cotton strips attached to the cord, ready to be deployed in the stream. Photo 2. Slide the cable binder through the opening that was made in the strip. Photo 4. Photos showing the cotton strips being installed in the stream (above), and riparian zone (below).
