Hydrologic modelling of Humber River Basin
The physiographic features of Newfoundland create many challenges for hydrological analysis of watersheds on the island. The most recent glaciations have deepened valleys and altered drainage networks due to the deposition of glacial drift material. The Humber River Basin (HRB), located on the west...

The physiographic features of Newfoundland create many challenges for hydrological analysis of watersheds on the island. The most recent glaciations have deepened valleys and altered drainage networks due to the deposition of glacial drift material. The Humber River Basin (HRB), located on the west coast of Newfoundland, is the second largest river basin (7068 Km²) on the island, and several communities within the basin are subject to flooding due to extreme events. It is expected that the magnitude and frequency of extreme events will increase with climate change, and impact analyses are required to assess vulnerability of communities within the basin to climate change. For proper assessment, a hydrologic model is indispensable for the watershed in this complex terrain. The present study analyzed the streamflow derived from the drainage basin by cold regions hydrological simulation. The Cold Regions Hydrological Modelling platform (CRHM) was used to create a hydrological model for HRB boreal regions with physically-based modules were also sequentially linked in CRHM to simulate snow processes, frozen soils, variable contributing area and wetland storage and runoff generation.
