Hydroelectric power systems use pipes and open channels to convey water over distances from a few hundred metres to many kilometres. The efficiency of water conveyance in these systems is affected by the surface roughness. Contributing factors are the surface roughness of the construction material or its coating, and the roughness caused by biofilms that accumulate over time on the surface. This paper describes photogrammetric methods that are being developed to measure the surface roughness of pipes and open channels in the Tasmanian hydroelectric power system, and to monitor the accumulation of biofilms. This work contributes to a cross-disciplinary study of biofilm accumulation and conveyance efficiency in hydroelectric power systems.
