Mississippi River Basin belongs to the western slope of the Appalachians, as well as most of the Central and Great Plains of North America. Nutrition River is mainly due to favorable snow-rain regime. Generally due to different climatic conditions, the eastern and western parts of the basin differ on water features. Right tributaries descend and flow of the Rocky Mountains through the arid lands. That is why even after the merger with Missouri Mississippi remains relatively shallow. Great river, it becomes only after merging with the river Ohio. Below the confluence of the Ohio, Mississippi, increases the flow of water in 1,5 times. That is why the regime of the river downstream to a large extent determined by the mode of the Ohio River. If the period of snowmelt in Appalachia coincides with the maximum rainfall, the level of the river in Ohio up to 15-20 meters in the Lower Mississippi River - at 5-6 meters. And this leads to the flooding of much of the floodplain. Spill Mississippi contribute to the peculiarities of its valley. At the confluence of the Mississippi Gulf of Mexico constitutes one of the largest in the world wide fast-growing delta and deposition of clastic material - gravel, gravel, sand, and others. In the flood of the river often overflows its banks. It blurs the coastal trees and flooding the upper floodplain, sometimes on an area up to a thousand square kilometers. Mississippi - a convenient way for water from the Atlantic Ocean through the Gulf of Mexico to the central regions of the continent.
