Lawrence basin, the Pacific basin, the Arctic basin, the Hudson Bay basin, and the Great Basin. Together, the principal basins span the continent with the exception of numerous smaller endorheic basins.
What is the most common drainage basin?
The three main types of drainage patterns are illustrated in Figure 13.7. Dendritic patterns, which are by far the most common, develop in areas where the rock (or unconsolidated material) beneath the stream has no particular fabric or structure and can be eroded equally easily in all directions.

What are the three zones of a drainage basin?
Channel width and depth increase downstream as the drainage area and discharge increase. A simplified longitudinal model captures these observed changes by disaggregating the river into three zones: headwaters zone, transfer zone, and depositional zone (Figure 1.2).
Where are the watersheds in Canada?
Canada’s Watersheds
Canada has 5 ocean watersheds: The Arctic, Atlantic, Hudson Bay, Pacific, and the Gulf of Mexico. All of Canada’s water is drained into these 5 areas before reaching the sea. This is done by moving through sub-watersheds. Sub-watersheds are determined naturally by land topography.
