Duncan Dam Water Use Plan DDMMON3 Lower Duncan River Hydraulic Model Year 5 Report. Prepared for BC Hydro
Author: N.H.C.
This report summarizes the development of predictive tools for integrating habitat use with water flows at a range of operations to quantify operating impacts on habitat displacement. The hydraulic model was upgraded from a steady state simulation using RIVER2D to an unsteady simulation using TELEMAC2D. With the unsteady model, implementation of refined analytical tools for assessing flow ramping effects was possible.
Transferring the model from steady state to unsteady using TELEMAC2D enabled a greatly improved analysis of flow ramping effects. Proof of concept was achieved, showing that the unsteady hydraulic model could indicate potential stranding conditions in sufficient resolution to distinguish habitat types. However, quantitative data regarding the severity of fish stranding would be required to validate the model results.
