The data for method 2 is from a list maintained by the Office of Ocean and Coastal Resource Management of NOAA. [note 1] The state coastline lengths were computed by an unspecified method that includes tidal areas not included in the first method. [3] These numbers also include the Great Lakes coastlines, which do not have similar tidal areas.
Coastal hazards are physical phenomena that expose a coastal area to the risk of property damage, loss of life, and environmental degradation.Rapid-onset hazards last a few minutes to several days and encompass significant cyclones accompanied by high-speed winds, waves, and surges or tsunamis created by submarine (undersea) earthquakes and landslides.
Illinois' southeastern and southern boundary is along the Wabash River and the Ohio River, whereas its northern boundary and much of its eastern boundary are straight survey (longitudinal and latitudinal) lines. Illinois has a maximum north–south distance of 390 miles (630 km) and 210 miles (340 km) east-west.

Coastal flooding during Hurricane Lili in 2002 on Louisiana Highway 1 (United States). Coastal flooding occurs when dry and low-lying land is submerged by seawater. [1] The range of a coastal flooding is a result of the elevation of floodwater that penetrates the inland which is controlled by the topography of the coastal land exposed to flooding.
Coastal erosion is one of the most significant hazards associated with the coast. Not in terms of a rare massive release of energy or material resulting in loss of life, as is associated with tsunami and cyclones, but in terms of a continual chronic release that forms a threat to infrastructure, capital assets and property.

Aug. 2—The National Weather Service has extended its coastal hazard message for Hawaii to Thursday afternoon. Due to summer king tides, minor coastal flooding may occur in low-lying areas of the ...
