Recognize value of the floodplain Floodplain regulation, hazard maps Requires Zoning and Planning - delineate past floods or floods of a particular frequency (e.g., 100-year floodplain). Restrict development. Coastal Processes Longshore Current -Longshore Drift of Sediments Sources of Sediment Input and Output Coastal Features: Spit, Baymouth-Bar, River Mouth Coastal Management Structures: Jetties, Breakwater, Sea wall “Beach Nourishment” Planning and Zoning (Adjustment) Mass Wasting General term for mass movement of earth material at earth’s surface Driving and Resisting Forces Classification Causes: “Triggering Events” Prevention / Adjustment Driving and Resisting Forces *Safety Factor: Resisting/Driving S.F. >1 = stable slope S.F.>1 = unstable slope (failure) Driving Forces: Gravity (mass of material) weight of geologic material (grade of slope)
