Bruno Creek diversion Option 1A design review, Colombia

Cerrejon Coal proposed the diversion of Bruno Creek from its current alignment to enable access to new open cut coal reserves. Bruno Creek is a right bank tributary of the Rancheria River located near the northern limit of the current mine boundary. Alluvium was contracted to review the design of a preferred arrangement for a short potentially interim diversion. Alluvium assessed the design for ecological sustainability and short and long term geomorphic stability.
