AB: We evaluate the impact of climate change on the water balance in the Pacific Northwest. A stochastic weather generator is used to generate meteorological data with precipitation and air temperature both modeled for wet and dry periods. The meteorological forcing is used to estimate snow state and streamflow through a simplified hydrologic model developed at Pacific Northwest National Laboratory (PNNL). The model itself is calibrated on the historical data before running for the synthetically generated meteorological data. A number of climate scenarios based on precipitation and temperature are designed and are used to study the impact of those scenarios on the streamflow and snow pack volumes. The findings can have direct relevance for the operation and management of water resources in the Pacific Northwest.
