Hydrological and Hydraulic Modelling Case Studies
| McKays Creek Flume Replacement | |
| The McKays Creek power station, located on the West Coast, was originally commissioned in 1931 with water being diverted from the Kaniere River through 3.3km of open race, 500m of tunnel and 300m of flume to a small power station generating 1.1MW of electricity. The recent need for an upgrade highlighted the fact that the existing 220m wooden trestle flume, crossing Blue Bottle Creek, was unable to pass consented flow of 5m cubic metres per second. The flume had also become a safety hazard. |

| Arnold Valley HEPS | |
| Review of hydrology associated with the development of a proposed power scheme near Greymouth, including the development of a MIKE 11 model of the Arnold and Grey Rivers and an assessment of the power station effects on the Arnold River below the outfall. Consent was granted for this project. |  |
