Stream Bed Simulation Rock 705.08 Channel Rock 705.07

648.03 General Place stream simulation rock on a prepared surface to form a well-graded, low permeability mass, similar in appearance and texture to the natural streambed.

The placement of stream simulation rock and channel rock shall be done when the channel is dewatered. Before the stream is diverted back into the new channel, wash the new channel, and collect the sediments (if any) and remove the sediments from the channel via the use of SEDIMAT or approved equal.

All stream simulation material and channel rock shall be in place and the channel approved by the Engineering Representative (ER) prior to the introduction of the stream.

648.04 Placed Stream Simulation Rock and Fish Rest Stops.

a) Method A, Machine Placed. Place stream simulation rock in one or more layers with a layer depth less than 1 ½ times the maximum dimension of the stream simulation rock. Place stream simulation bedrock by methods that do not cause segregation or damage to the prepared surface. Place or rearrange individual rocks by mechanical methods to obtain a compact low permeability mass matching stream simulation bed details. Fill voids with foundation fill before placing the next lift. Place fish rest stop rock as designated.

b) Method B, End Dumped. Dump stream simulation rock in one or more layers with a layer depth less than 1 ½ times the maximum dimension of the stream simulation rock. Distribute larger rocks throughout the mass of stone. Obtain a uniformly dense, compact, low permeability bed with a surface matching stream simulation bed details.

Fill voids before placing next lift. Place fish stop rock as designated.

Material may be hand carried, or carried in wheelbarrows and end dumped to obtain its full thickness. Compact each load using hand operated mechanical equipment to obtain uniformly dense, compact, low permeability bed with a surface matching stream simulation bed details. Fill voids before placing the next lift. Place fish rest stop rock as designated.

648.04 Foundation Fill. Fill all voids left during placement of Stream Bed Simulation Rock with fines. The fines shall be well-graded compactable material free of muck, frozen lumps, roots, sod or other deleterious material. Use water pressure, metal tamping rods, and similar hand operated equipment to force material into all surface and subsurface voids between the structure and individual rocks. The purpose of filling the voids with fines is to create a streambed that will be non-porous enough to keep water flowing on the top surface, even at low flows.

648.05 Acceptance. Placing stream simulation material will be evaluated under Subsections 106.02 and 106.04.

648.06 Measure the items listed in the schedule according to Subsecion 109.02
