Lead, Hydrologic Impacts

Markus Schnorbus joined PCIC in April 2009 and became Lead Hydrologist in July 2010. Prior to joining PCIC Markus was a Hydrologic Modelling Scientist and Forecaster with the BC Ministry of Environment, River Forecast Centre, where he was engaged in the analysis of observed climate and hydrometric data and the application of various hydrologic models for flood, drought and seasonal streamflow forecasting. He also recently led the implementation of the Variable Infiltration Capacity (VIC) macro-scale hydrology model to investigate the effects of mountain pine beetle and salvage harvest operations within the Fraser River watershed. During this time, Markus developed a clear and pragmatic appreciation of the hydrologic effects of climate change and variability.

Markus possesses a sound knowledge of mountain and forest hydrology, particularly in the context of British Columbia, and has a strong understanding of the challenges inherent in applying hydrology models in this complex environment. Markus leads the effort at PCIC to quantify the direct and indirect effects of climate change and variability upon the various components of hydrologic cycle at the local and regional scale.
