     oil spilled on water is seldom completely contained and recovered and some of it eventuall reaches the shoreline the fate and behavior of oil on shorelines is influenced by many factors, some of which relate to the oil is deposited on the shoreline, such as weather and waves. these factors include the type and amount of oil, the degree of weathering of the oil, both before it reaches the shoreline and while on the shoreline, the temperature, the state of the tide when the oil washes on shore, the type of beach substrate, i.e., it's material composition, the type and sensitivity of biota on the beach, and the steepness of the shore, the extent that an oil penetrates and spreads, its adhesiveness, and how much the oil mixes with the type of material on the shoreline and all important factors in terms of clean up.there are many types of shorelines, all of which are classified in terms of sensitivity of oil spills and ease of clean up. the types discussed here one: bedrocks, man-made solid structures, boulder beaches, pebble- cobble, mixed sandgravel beaches, sand beaches, sand tidal flats, mud tidal flats, marshes, peat and low-lying tundra,and mangrove .the primary objective of clean up operation is to minimize the effects of the stranded oil and accelerate the natural recovery of affected areas.obviously, a clean up technique should be safe and effective and not be so intusive as to cause more damage than the oil itself (fingas,2000)
