Watersheds and Drainage Basins
Watersheds and Drainage BasinsWhere does our water flow from and
into?A watershed is a landform defined by highpoints and ridgelines
that descend into lower elevations.
A watershed carries water shed from the land after rain falls
and snow melts.
The water of the area flows across or through on its way to a
particular water body, such as a stream, river, wetland or coast of
a drainage basin.What is a watershed?What does it look like?
What does a Drainage Basin look like?
A drainage basin is an extent or area of land that drains all
precipitation (rain, melting snow, ice) received as runoff from
watershed.
The runoff converges to a single point, usually the exit of the
basin, where the waters join another body of water, such as a
river, lake, wetland, sea, or ocean.What is a Drainage Basin?Canada
has 5 main watersheds:
The Arctic
The Atlantic (includes the Great Lakes and St. Lawrence
River)
Hudson Bay
The Pacific
The Gulf of MexicoWatersheds and Drainage Basins in Canada
