Hello SWMMers,

Does anyone have experience designing trash racks for open channels? We have an application for such a device to protect a wetland area from becoming littered with floating debris (cans, plastic containers, etc). The trash rack would be installed upstream of the wetland area on an existing open channel. Drainage area to the proposed trash rack is approximately 3800 acres of urban land use.

It is our goal to install a system that diverts floating debris from the channel to a collection point adjacent to the stream. Periodically, the trash would be removed from the collection area. The system should be completely passive (not motorized) and functional up to 1000 cfs at 3 ft/sec.

I would appreciate any suggestions.
