These are constructed across water courses as grade control structures, energy dissipaters, sediment collectors, as well as to form reservoirs, for water irrigation, and water supply in general. Gabion weirs are normally provided with a gabion scour protection apron both on their downstream side and at the upstream approach zone. The weir's crest or crown is frequently protected with a thin layer of grout for impact and abrasion protection to the steel wire. This unique application uses gabions as a filter system to collect debris and litter which might detract from the otherwise very scenic quality of the Concho River Walk.
Water flows through the gabion wall but litter is trapped behind for easy removal by city crews.
