Dr. N.J. Vidics Gel 001 21 April 2008 Today, the most threatened area in the event of a flood would be in my hometown, Sacramento. It lies in between two large rivers, the American River and the Sacramento River. To add on, there are big areas that rely heavily on levees to protect them from floods (Kollars, 2008). As Sacramento expands, flood threats become more threatening to the residents. This city has the greatest risk of flooding of any major city throughout all of the United States (SAFCA, 2008). Over the course of 40 years, there have been five record floods in this county (SAFCA, 1997). These floods are due to the slow erosion of levees and the fact that much of Sacramento lies under the levees, surrounding homeowners are extremely worried (Ritter, 2006). Looking over the flood history of this city, it is prominent that these levees and dams need a huge upgrade - one qualified for high level protection. It needs one worthy for a growing city like Sacramento. Before I give you reasons to why Sacramento needs a taller and stronger levee, I will provide information on levees and floodplains. Levees are walls or slopes that help keep floodplains dry and away from floods. They can either be naturally or artificially made. Floodplains form when water flows out of a stream and goes on either side until it stops at a bluff. They become lands that lie low on both sides of a river and eventually becomes submerged under water in the event of a heavy flood (Marshak, 2008). When water begins to recede from the flood, natural levees begin to form when sediments from the floodplain rest on the edge of the channel. This is due to the friction of water and ground and the slow flow of the

water that allows the large sediments to rest on the bank of the stream. The most popular levee failure is the levee breach. This occurs when a part of the levee is broken off and water spills out into the floodplain. With this knowledge along with the knowledge of the city of Sacramento, I am going to argue that the city needs stronger flood control system. 1,660 miles of state, federal, and private owned levees were California’s flood control
