Sweetwater Creek (west Of Atlanta)
Sweetwater Creek is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map, accessed April 15, 2011 stream in the U.S. state of Georgia, west of Atlanta. It begins in southwestern Paulding County, flowing generally eastward into southwestern Cobb County, then turning south into eastern Douglas County. It is a tributary of the Chattahoochee River, and near its end it is the centerpiece of Sweetwater Creek State Park. Sweetwater Creek was named after AmaKanasta (Sweet Water), a Cherokee chieftain. Since 1904 there has been a stream gauge near Austell (actually in Lithia Springs), at latitude 33°46'22"N, longitude 84°36'53"W. The watershed area above this point is . It is above mean sea level. The flood stage at this point is . The identifier for this gauge is ''AUSG1''. Major flooding occurred here in July 2005, after Hurricane Dennis dumped enormous amounts of rain across the Sweetwater Creek watershed, just after it ...

Flood Stage
Flood stage is the water level or stage at which the surface of a body of water has risen to a sufficient level to cause sufficient inundation of areas that are not normally covered by water, causing an inconvenience or a threat to life and property. When a body of water rises to this level, it is considered a flood event. Flood stage does not apply to areal flooding. As areal flooding occurs, by definition, over areas not normally covered by water, the presence of any water at all constitutes a flood. Usually, moderate and major stages are not defined for areal floodplains. Definition Flood stage is the water level, as read by a stream gauge or tide gauge, for a body of water at a particular location, measured from the level at which a body of water threatens lives, property, commerce, or travel. The term "at flood stage" is commonly used to describe the point at which this occurs. "Gauge height" (also referred to as "stream stage", "stage of the ody of water, or simply "stage" ...

500-year Flood
A 100-year flood is a flood event that has a 1 in 100 chance (1% probability) of being equaled or exceeded in any given year. The 100-year flood is also referred to as the 1% flood, since its annual exceedance probability is 1%.Holmes, R.R., Jr., and Dinicola, K. (2010) ''100-Year flood–it's all about chance 'U.S. Geological Survey General Information Product 106/ref> For coastal or lake flooding, the 100-year flood is generally expressed as a flood elevation or depth, and may include wave effects. For river systems, the 100-year flood is generally expressed as a flowrate. Based on the expected 100-year flood flow rate, the flood water level can be mapped as an area of inundation. The resulting floodplain map is referred to as the 100-year floodplain. Estimates of the 100-year flood flowrate and other streamflow statistics for any stream in the United States are available.Ries, K.G., and others (2008) ''StreamStats: A water resources web application 'U.S. Geological Survey, Fac ...

Interstate 285 (Georgia)
Interstate 285 (I-285) is an auxiliary Interstate Highway encircling Atlanta, Georgia, for . It connects the three major Interstate Highways to Atlanta: I-20, I-75, and I-85. Colloquially referred to as the Perimeter, it also carries unsigned State Route 407 (SR 407) and is signed as Atlanta Bypass on I-20, I-75, and I-85. Because of suburban sprawl, it is estimated that more than two million people use the highway each day, making it the one of the busiest Interstates in the Atlanta metropolitan area, and one of the most heavily traveled roadways in the US. During rush hour, portions of the highway slow, sometimes to a crawl. Route description I-285 is 8 to 12 lanes wide, with the northern part from I-75 to SR 400 to I-85 the most heavily traveled. One segment of the highway near Tom Moreland Interchange (a large, flyover highway interchange northeast of Atlanta colloquially called Spaghetti Junction) with I-85 widens to 18 lanes, including ...

2009 Southeastern United States Floods
The September 2009 Southeastern United States floods were a group of floods that affected several counties throughout northern Georgia, Tennessee, Alabama, Mississippi, and Arkansas. The worst flooding occurred across the Atlanta metropolitan area. Continuous rain, spawned by moisture pulled from the Gulf of Mexico, fell faster than the local watersheds could drain the runoff. Initial damages from around the state were estimated at $250 million. On September 26, Georgia Insurance Commissioner John Oxendine raised the estimated cost to $500 million with the potential for it to rise. Some 20,000 homes, businesses and other buildings received major damage and 17 Georgia counties received Federal Disaster Declarations. The flood is blamed for at least ten deaths. The floods were historic, breaking records that went back more than a century in some locations. The Chattahoochee River, the largest river in the region, measured water levels at a 500-year flood level. Beginnings Rain b ...

Flood Plain
A floodplain or flood plain or bottomlands is an area of land adjacent to a river which stretches from the banks of its channel to the base of the enclosing valley walls, and which experiences flooding during periods of high discharge.Goudie, A. S., 2004, ''Encyclopedia of Geomorphology'', vol. 1. Routledge, New York. The soils usually consist of clays, silts, sands, and gravels deposited during floods. Because the regular flooding of floodplains can deposit nutrients and water, floodplains frequently have high soil fertility; some important agricultural regions, such as the Mississippi river basin and the Nile, rely heavily on the flood plains. Agricultural regions as well as urban areas have developed near or on floodplains to take advantage of the rich soil and fresh water. However, the risk of flooding has led to increasing efforts to control flooding. Formation Most floodplains are formed by deposition on the inside of river meanders and by overbank flow. Whereve ...

Hurricane Cindy (2005)
Hurricane Cindy was a tropical cyclone that briefly reached minimal hurricane strength in the Gulf of Mexico during July in the 2005 Atlantic hurricane season and made landfall in Louisiana. It was the third named storm and first hurricane of the season. Cindy was originally thought to have been a tropical storm at peak strength, but was upgraded to a Category 1 hurricane in the post-season analysis. Cindy formed on July 3 just east of the Yucatán Peninsula in the Caribbean Sea. The depression soon made landfall on the peninsula and weakened before reemerging in the Gulf of Mexico on July 4. The storm strengthened as it moved north becoming a hurricane just before making landfall near Grand Isle, Louisiana, on July 5. The storm weakened as it moved overland and became extratropical on July 7. The storm was responsible for 3 deaths in the United States and brought heavy rains to Louisiana, Mississippi, Alabama and Maryland. An unusually strong F2 to ...
