High Resolution Modeling of Climate Change Impacts on Water Supply and Demand, and GHG Emissions, Similkameen Watershed, BC, Canada
Abstract
In western North America, water supply is largely derived from mountain snowmelt. Climate change will have a significant impact on mountain snowpack and subsequently, the snow-derived water supply. This will strain water supplies and increase water demand in areas with substantial irrigation agriculture. This work will address a series of objectives based on a range of future climate scenarios in the Similkameen watershed, BC, Canada. First, to improve GIS-based radiation estimation by modelling local atmospheric transmissivity and diffusion functions. Second, to model historical and future water supplies under a range of climate scenarios using the Generate Earth Systems Science (GENESYS) model. Third, to assess climate driven changes in water requirement and associated crop productivity for a range of future climate scenarios using the GENESYS. Fourth, to link the GENESYS and the Holos model to estimate farm and regional level GHG emissions for the crops and land covers in the watershed.
