Topography

The state is bordered to the west by the state of Texas; to the north by Arkansas; to the east by the state of Mississippi; and to the south by the Gulf of Mexico.

The surface of the state may properly be divided into two parts, the uplands, and the alluvial and coast and swamp regions. The alluvial regions, including the low swamps and coast lands, cover an area of about 20,000 square miles (52,000 km²); they lie principally along the Mississippi River, which traverses the state from north to south for a distance of about 600 miles (1000 km) and ultimately emptying into the Gulf of Mexico, the Red River, the Ouachita River and its branches, and other minor streams. The breadth of the alluvial region along the Mississippi is from 10 to 60 miles (15 to 100 km), and along the other streams it averages about 10 miles (15 km). The Mississippi flows upon a ridge formed by its own deposits, from which the lands incline toward the low swamps beyond at an average fall of six feet per mile (3 m/km). The lands along other streams present very similar features. These alluvial lands are never inundated save when breaks occur in the levees by which they are protected against the floods of the Mississippi and its tributaries. These floods, however, do not occur annually, and they may be said to be exceptional. With the maintenance of strong levees these alluvial lands would enjoy perpetual immunity from inundation.
