Abstract:

The uniqueness of the Jackpile Reclamation Project and the changes in reclamation technology over the past few years have prompted a reexamination of some of the design criteria specified by the Department of Interior in 1986. This reexamination resulted in revisions to the waste pile slope criteria that also affected the Rio Moquino design. This paper discusses the redesign evaluation for the stream stability and erosion protection of the Rio Moquino. The existing reclamation design called for relocation of the stream channel and heavy armoring of the stream banks with large riprap. The recent changes to the waste pile slope criteria created the possibility for a more flexible and cost effective approach for long-term stabilization of the Rio Moquino.
