Modelling future salinity in the Lower Fraser River

These resources provide the results of hydraulic modelling that evaluated the potential impacts of climate change and dredging on salinity in the Fraser River.

The modelling used low river flow and sea level rise scenarios to predict and analyze future salinity levels. Findings included near-term and long-term impacts on salinity by modelling the number of hours per day that water would be of sufficiently low salinity that it could be used for irrigation.

Near-term impacts (10-25 years) are projected to decrease daily irrigation water availability under low river flows by up to 25% or more during periods more extreme low flows.

The report includes recommendations for salinity monitoring locations and a salinity monitoring program.
