HYDRODYNAMIC MODELLING WITH BIG DATA IN SUPPORT OF DAM RENEWAL DECISION-MAKING
The Mactaquac Generating Station (MGS), a 672 MW run-of-the-river hydroelectric facility on the main-stem of the Saint John River, New Brunswick, Canada has been in operation since 1968 with a predicted end-of-life of 2030. In 2013, the Canadian Rivers Institute began the Mactaquac Aquatic Ecosystem Study (MAES), a planned, whole-river multidisciplinary ecosystem study and manipulation of the MGS, in support of a decision-making process regarding the future of the aging facility. Future options under consideration ranged from in-situ restoration to full removal and river restoration. This dam renewal will be the largest ever undertaken.
Prediction of the potential transport and fate (or long-term retention) of post-inundation sediment and its impact on the river ecosystem, along with changes in flow patterns, were crucial aspects for decision-makers. Four-years of extensive surveys, coupled with historical information, provided multiple sources of big data that were fed into the hydrodynamic model Delft3d including: bathymetry, flood-plain topography, water level, 3D flow direction and velocity, sediment quality and quantity, water quality, and limnology. The resulting output was used in decision-making and in supporting focused models of fish habitat and environmental flows.
