Explanation / Answer

Mississippi River in the US has the largest discharge of 593000 cubic feet per second.

The major tributaries are the Arkansas, Illinois, Missouri, Ohio and Red rivers.

Topography is the shape and physical features of land. The topography of a stream channel and its watershed reflects the geology of the watershed. In turn, watershed topography helps produce the pattern and distribution of stream channels. Topography of a watershed also determines the steepness of the land surface and stream channels.  The steeper the basin the more quickly it drains. Indented landscapes will collect water and reduce runoff rates, reducing the amount of water reaching the river channel.

The location of major continental drainage divides are . The Arctic Divide - It divides the the Arctic Ocean watershed and the Hudson Bay watershed.
The great divide - It runs from the Seward Peninsula in Alaska, through western Canada along the crest of the Rocky Mountains, including through Glacier National Park, Yellowstone National Park, and Rocky Mountain National Park, to New Mexico. From there, it follows the crest of Mexico's Sierra Madre Occidental and extends to the tip of South America. It is crossed by the Panama Canal and by the two outlets of Isa Lake in Yellowstone National Park
The Eastern Continental Divide- It separates the watershed of the Gulf of Mexico from the Atlantic Ocean. It runs from the Twin Tiers of New York and Pennsylvania along the Appalachian Mountains to the tip of Florida. The city of Atlanta sits atop this divide
The Laurentian Divide -separates the watershed of the Atlantic Ocean from that of Hudson Bay. The western part of it from Glacier National Park in the Rocky Mountains to the Great Lakes watershed marked the northern boundary of the Louisiana Purchase
The Saint Lawrence River Divide - IT separates the Great Lakes Basin from the rest of the Atlantic Ocean watershed. Two canals cross the divide: The Chicago Sanitary and Ship Canal crosses the Chicago Portage and connects Lake Michigan to the Mississippi River watershed.
