http://en.wikipedia.org/wiki/Mississippi_River
The Mississippi River is the largest river system in North America. About 2,320 miles (3,730 km) long, the river originates at Lake Itasca, Minnesota, and flows slowly southwards in sweeping meanders, terminating 95 miles (153 km) by river below New Orleans, where it begins to flow to the Gulf of Mexico. Along with its major tributary, the Missouri River, the river drains all or parts of 31 U. S. states stretching from the Rocky Mountains in the west to the Appalachian Mountains in the east to the Canada–US border on the north, including most of the Great Plains, and is the fourth longest river in the world and the tenth most powerful river in the world. The current form of the Mississippi River basin was largely shaped by the Laurentide Ice Sheet of the most recent Ice Age. The southernmost extent of this enormous glaciation extended well into the present-day United States and Mississippi basin. When the ice sheet began to recede, hundreds of feet of rich sediment were deposited, creating the flat and fertile landscape of the Mississippi Valley. During the melt, giant glacial rivers found drainage paths into the Mississippi watershed, creating such features as the Minnesota River, James River, and Milk River valleys. When the ice sheet completely retreated, many of these ‘temporary’ rivers found paths to Hudson Bay or the Arctic Ocean, leaving the Mississippi Basin with many features ‘oversized’ for the existing rivers to have carved in the same time period. The Mississippi River Delta has shifted and changed constantly since the formation of the river, but the construction of dams on the river has greatly reduced the flow of sediment to the delta. In recent years, the Mississippi’s mouth has shown a steady shift towards the Atchafalaya River channel, but because of floodworks at the river’s mouth, this change of course—which would be catastrophic for seaports at the river mouth—has so far been held at bay. Some researchers believe that due to natural forces inherent to river plains, it is a matter of time before this event takes places and that it becomes more likely each year. Hundreds of Native American tribes have depended on the Mississippi River and its tributaries for thousands of years. Although they knew the river by many different names, it was the Ojibwe word misi-ziibi, meaning Great River, or gichi-ziibi, meaning Big River, that ultimately gave the river its present-day name. European explorers reached the mouth of the river as early as the 16th century and 17th century. The river throughout history has served as the border for New France, New Spain, and the early United States—its size and importance made it a formidable boundary as well as a strategic military location, and later, an important artery for steamboats to travel on. Writer Mark Twain was one of the most well-known figures on the river in this period. Even today, the river serves as partial boundaries for ten states, and most of its course can easily be seen on a political map. The Mississippi has also been known for great flooding events, especially in the 20th century which experienced up to four 100-year floods. This has led to the construction of hundreds of miles of levees along nearly the entire course of the river, although they have not always succeeded in preventing the greatest floods. Throughout its history, whether for Native Americans, explorers, or modern commerce, the Mississippi has always been a major navigation route through the center of North America. In the 19th and 20th centuries, despite its slow current and relative depth, a series of dams were constructed on the river, one of the most notable of which is at St. Anthony Falls in Minneapolis. These dams facilitate navigation for a steady stream of barge traffic carrying agricultural products from the fertile Mississippi Basin to the Gulf Coast, and like the Columbia River, most of the upper Mississippi is a cascade of reservoirs, as are many of its tributaries like the

http://en.wikipedia.org/wiki/Drainage_in_New_Orleans
Drainage in New Orleans, Louisiana has been a major concern since the founding of the city in the early 18th century, remaining an important factor in the history of New Orleans through today. Flooding threatens New Orleans from three sources: the Mississippi River, Lake Pontchartrain, and natural rainfall. Artificial levees have been built to keep out rising river and lake waters but have had the negative effect of keeping rainfall in. New Orleans was originally built on natural levees along the Mississippi River that were a result of soil deposits left from the river’s annual floods. The site chosen for New Orleans had many advantages. Because it sits where distance between the river and Lake Pontchartrain is shortest, Louisiana Indians had long used the area as a depot and market for goods carried between the two waterways. The narrow strip of land also aided rapid troop movements, and the river’s crescent shape slowed ships approaching from downriver and exposed them to gunfire, however flooding was always a hazard. The first artificial levees and canals were built in early colonial times. They were erected to protect New Orleans against routine flooding from the Mississippi River. The ‘back of town’ away from the river originally drained down into the swamps running toward Lake Pontchartrain. Flooding from the lake side was rare and less severe as most of the old town had been built on high ground along the riverfront. As the city grew, demand for more land encouraged expansion into lower areas more prone to periodic flooding. For most of the 19th century most residential buildings were raised up at least a foot above street level (often several feet), since periodic flooding of the streets was a certainty at the time. In the 1830s state engineer George T. Dunbar proposed an ambitious system of underground drainage canals beneath the streets. The goal was to drain water by gravity into the low lying swamps, supplementing this with canals and mechanical pumps. The first of the city’s steam engine powered drainage pumps, adapted from a ship’s paddle wheel and used to push water along the Orleans Canal out to Bayou St. John, was constructed in this decade. However, only a few of Dunbar’s plans were actually implemented as the panic of 1837 largely ended major systematic improvements for a generation. In 1859 surveyor Louis H. Pilié improved the drainage canals, bricking in some portions. Four large steam ‘draining machines’ were built to push water through the canals into the lake. In 1871, some 36 miles (58 km) of canals were built in the city for both improved drainage and small vessel shipping within town. However, despite earlier efforts, at the end of the 19th century it was still common for water to cover streets from curb to curb after rainstorms, sometimes for days. In 1893, the city government formed the Drainage Advisory Board to come up with better solutions to the city’s drainage problems. Extensive topographical maps were made and some of the nation’s top engineers were consulted. In 1899, a bond was floated, and a 2 mill per dollar property tax approved, which funded and founded the Sewerage & Water Board of New Orleans. The Sewerage & Water Board had the responsibility of draining the city along with constructing a modern sewage and tap water system for the city, which, at the time, still relied heavily on cisterns and outhouses. (A different entity, the Orleans Levee Board, is in charge of supervision of the city’s levee and floodwall system. )The Sewerage & Water Board found A. Baldwin Wood, a young engineer who not only supervised the plans for improved drainage and pumping, but also invented a number of improvements in pumps and plumbing in the process. These improvements were not only used in New Orleans, but adopted all over the world.

http://en.wikipedia.org/wiki/Floods_in_the_United_States:_1901%E2%80%932000
Floods in the United States are generally caused by excessive rainfall, excessive snowmelt, and dam failure. Below is a list of flood events that were of significant impact to the country, between 1901 and 2000. The third deadliest flash flood in US history, the normally placid Willow Creek burst its banks during an intense rain and hail storm. The city of Heppner, at the foothills of the Blue Mountains in eastern Oregon, was almost completely destroyed. 220 of Heppner’s 1,400 residents died in the flood. Flooding was more significant along the Grand, Saginaw, Kalamazoo, and River Raisin river basins than the St. Joseph and Huron River basins. In Lansing, it was the worst flood in the previous 135 years of its history. Many dams were either undermined or swept away. Kalamazoo saw two square miles of flooding during this event. It was also considered the most destructive flood in Grand Rapids history. The Grand River went above bankfull on the night of March 24, rising slowly for the next four days. It broke the previous high water mark by over 60 cm (2. 0 ft), and was considered a once in 100 year flood. Over one-half of the population on the west side of the river was inundated. On the east bank of the river, numerous factories went underwater. There was one casualty. Damages totaled US$1. 8 million (1904 dollars). To the left is an image showing the flooding in Battle Creek. A storm in late 1906 reported highest ever rainfalls in a southeast to northwest direction from Monterey to Ione in the Sierra Nevada foothills. An area of 300,000 acres (1,200 km2) was flooded in the Sacramento Valley. Snowmelt combined with heavy rains by March 16 allowed the Allegheny, Monongahela, and Ohio rivers to swell out of their banks, leading to a flood of record in Pittsburgh. Damage to the city was estimated at US$5 million (1907 dollars). The death toll was low, with 6–12 perishing during the inundation. In February, snowstorms had deposited a significant snowpack across the region. Then, in early March, heavy rains and warmer conditions set in, setting the stage for a flood. The Kalamazoo River flooded Albion when the Homer Dam broke around 3 p. m. on March 7. By midnight, the bridges surrounding town were underwater. Six buildings in Albion collapsed, which caused over US$125,000 in damage (1908 dollars). The storm extended from Fort Ross on the coast to the Feather River basin. LaPorte, in the Feather River basin, had 1,458 mm (57. 4 in) of rain in 20 days, an event with a return period of 12,000 years. The flood episodes of 1907 and 1909 in California resulted in an overhaul of planned statewide flood control designs. Heavy rains filling the Bayless reservoir cracked the concrete dam, sending an estimated 450,000,000 gallons downstream destroying most of the boroughs of Austin and Costello. A total of 78 people from Austin and 2 from Costello perished during the inundation. Nearly 254 mm (10. 0 in) of rain during a series of three winter storms led to this flood event, which affected southwest, central, and eastern Ohio, especially cities and towns along the Great Miami River and Olentangy River valleys, as well as Indianapolis, eastern Indiana, and western Pennsylvania. Fires and tornadoes also wrought destruction. Dayton was totally devastated, being inundated for three days in late March. The floods also put the Ohio and Erie Canal out of business for good, destroying most of the locks and many miles of embankments. The death toll from this flood was 361 with total damages of US$100 million. On the Olentangy River, this flood broke the previous record for river stage by over 4. 5 m (15 ft). In the town of Delaware, Ohio, 50–75 perished when a break in the levee allowed a 7-foot-tall (2. 1 m) wall of water to sweep through downtown. Five of the town’s bridges washed away. The state capital, Columbus, suffered its worst ever flooding from the Olentangy and Scioto rivers.
