COASTAL FLOOD PROBLE~ffi <br /> <br />131. Flooding, Wind, and Erosion Problems <br /> <br />Coastal flooding is a complex phenomenon often <br /> <br />involving \dnd, \~ater and erosion. For example, a building <br /> <br />placed at the \,'a ter "s edge may De damaged or destroyed by a <br /> <br />combination of winds, inundation by high tides, storm <br /> <br />'surges and ,,'aves, and erosion which undermin8s tne found a tion . <br /> <br />Separation of wind, water and erosion as discrete damaging <br /> <br /> <br />forces is often impossible since they operate conjunctively <br /> <br />to produce damage " <br /> <br />Programs to reduce flood losses, <br /> <br />therefore, often combine elements to reduce damage from <br /> <br />water, wind, and erosion. However, at a given locality one, <br /> <br />element may predominate, For example, Pacific and Great Lakes <br /> <br />coast communities are not subject to hurricane wind damage <br /> <br />like those on the Gulf Coast and Atlantic seaboard. But, <br /> <br />erosion damage is often serious. A regulatory program to <br /> <br />reduce flood losses must be tailored to the needs of each <br /> <br />state and community. <br /> <br />132.
