Site-specific meteorological and climatological analyses were completed for a large mining complex in the complex terrain of the coastal mountains in northern British Columbia. These analyses developed PMP, annual exceedance probability, climate change assessments, long term climatologies, stochastic weather outputs, SPAS gridded rainfall analyses for model calibration, snow water equivalent and snowmelt parameters, and recurrence intervals for numerous meteorological parameters. This information was consolidated into a GIS tool and provided for detailed hydrologic and engineering design and environmental assessments applications.
AWA unique gridded process allowed all of these outputs to be developed for the entire domains which encompassed steep mountains, valleys and riverine systems where that greatly improved the accuracy of the outputs. This also provided the flexibility to evaluate the hydrology of the region for any locations within the entire domain down to a single point.
All outputs were presented as part of a detailed presentation involving all study participants to explain the methods, projections, and recommendations and included in a detailed set of documentation. These have also been presented during several Independent Review Board and Due Diligence meetings.
