Establecimiento de criterios geomórficos de referencia para el diseño de desvíos fluviales en torno a los pozos mineros de Pilbara, Australia Occidental

Abstract The poor condition of river diversion channels can prevent mining companies from relinquishing their mine to the government after has ceased. Many regions lack a locally derived template for integrating appropriate geomorphic and hydraulic conditions unmodified into designs help guide post-mining closure activities. Establishing baseline reference criteria catchments restoration efforts allow recovery stability fluvial system. Design-wise, should be built so that flow are able move sediment, but not high enough accelerate erosion in channel. We used natural headwater inform regional artificial constructed Pilbara, Western Australia. provide guideline specific channel types, including velocity, stream power, bed shear stress values five key types: alluvial single thread (≥ cobble) (sand), bedrock/confined sections, island-barform channels, heavily vegetated channels.
