ABSTRACT |
The purpose of this study- is to clarify the effects of wave and tidal actions on the penetration of spilled oil into sandy beach and to evaluate the influence of the penetrated oil on seawater infiltration by wave action in sandy beach and its ecological implications. Infiltration process of seawater and fuel oil C into sediments and the effect of the penetrated oil on seawater were evaluated by use of a sandy beach simulator.
Seawater was infiltrated by both wave action and tidal fluctuation into the sandy beach sediments. However, spilled fuel oil C penetrated into the sediments only by tidal fluctuation and not by wave action. The first tide is the most important for the penetration of stranded oil. Penetration depth is significantly affected by stranded oil volume. The infiltration of seawater was reduced by the increase in the penetrated oil volume and blocked about 91% when oil volume was 4 L/m2. The reduction of seawater infiltration in flooded condition will result in the decrease in the supplies of oxygen, nutrients and organic matters necessary for the survival of benthic organisms in sandy beach.
