A Natural Channel Design Approach to Stream Restoration on Reclaimed Surface Mine Lands

Abstract

Natural channel design methods are being considered for the purpose of re-establishing stable stream channels and valleys on reclaimed surface mine lands. Natural channel design is the process of applying fluvial geomorphic principles to transform unstable stream corridors into stable channels that maintain their dimension, pattern, and profile over time. Additional goals include improving aquatic habitats and restoring native riparian vegetation. Natural channel design concepts are reviewed in the context of their application to reclaimed mine lands. A tributary to the Mitchell River in the Blue Ridge Mountains of North Carolina is used as a case study demonstrating techniques that may be applied to reclaimed surface mine land sites.
