=Causes and Hazards:= Causes For flash fluds are stuff like overflowing rivers. Lakes and lots of polution. The hazards from this is that the bridges might get damaged and the car's, homes, and school. These are bad things that can happen.

=Flood Background Reaserch For Neosho Flood Excercise:= The //Great Flood// during the summer of 1993 was the largest flood of the 20th century in the north-central United States. Many stream gauging stations in the Mississippi and Missouri basins set all-time historical records. For example, on August 1, 1993, the Mississippi River at St. Louis peaked at 1,080,200 cfs (30,588 m3/s) flow. Rivers in eastern Kansas also experienced high flows and significant local flooding. Prior to 1993, the largest historical flood in eastern Kansas occurred during the summer of 1951. This flood resulted in widespread damage and economic loss. It led to construction of several flood-control reservoirs, levees, and other drainage structures. These structures were largely successful in lessening the impact of flooding during 1993. Reservoir operation has the general effect of reducing peak downstream discharge by spreading the high flow over a longer time interval--weeks or months instead of days. For this exercise, students will analyze the history of flooding on the upper Neosho River in east-central Kansas--see drainage [|maps]. We will utilize peak annual flow data from the **Americus** and **Iola** gauging stations. These stations are located respectively above and below John Redmond Reservoir. This lake is a flood-control reservoir located in Coffey County; it began operation in 1961. River flow at the Iola gauging station is fully regulated by John Redmond Reservoir; flow at the Americus gauging station is partly controlled by the upstream Council Grove Reservoir (Morris County).
