The velocity of a river is greatest during the spring then any other season, due to the heavy rainfall during spring and the melting of snow from winter. The water from these two drain into the tributaries. This causes the water in main stream or river to increase and frequently overflow its banks and levees, creating a floodplain. Since the disastrous flood of 1927, the U.S. Congress has authorized constructions of dams on the upper parts of the Mississippi River and its tributaries to stop it from flooding again and to regulate its flow. A system of Comprised levees, flood walls, and various control structures. These systems are placed 1,607 miles along the Mississippi River and some lie along the south banks of the Arkansas and Red rivers and in the Atchafalaya Basin. Regular inspections of maintenance are made by people from the U.S. Army Corps of Engineers and from local levee and drainage districts. It's essential to do these inspections because the levees have to be maintained in good condition for their proper functions in the flood control plan. Then, the water is diverted into different channels or water, such as the C
airo–New Madrid, Atchafalaya, and Morganza floodways and the Bonnet Carre Spillway at New Orleans, which then diverts the water into Lake Pontchartrain. The cutoffs in the Mississippi River have eliminated the dangerous wading of channels, and it improved main channel of the Mississippi has increased its flooding capacity.The Mississippi flood control has been successful, due to the fact that there has been no floods have destroy the system. Ever since the major flood in 1927, people that live along or near the Mississippi river have all came up with a plan of what to do if a flood does happen and how to stop a flood from happening. Since the regular inspections of all parts in the Mississippi to see if they are in good condition and all broke parts are immediately replaced. With this all parts in the system are always working as they are suppose to and have a less chance of breaking.
