Abstract/Description or Keywords Floods due to natural events and technical failures pose a significant hazard to communities and environments downstream of reservoirs throughout the world. Loss of life and economic impacts of such events have been widely addressed in the literature. Nevertheless, environmental impacts of such extreme events have not been systematically addressed. This work develops a framework for quantitatively estimating immediate and long-term environmental impacts of extreme floods. Several tools were developed to support this framework. These include: a probabilistic individual-based model that employs the results of a transient hydrodynamic model to estimate fish mortality during extreme floods; a geomorphologic tool that derives a probabilistic relationship between egg loss and flood intensity; and a population dynamics model to estimate long-term impacts, and resilience and vulnerability of the environmental systems downstream of reservoirs. Applicability of this framework is tested on the case study of Campbell River in British Columbia, Canada.
