摘要

The event of oil spill and an oil release into the sea were often found in the gulf of Thailand and it caused serious effects and damages to natural resources, environment and communities. A prompt collection and limiting the spread area of oil spill can reduce some damages and losses. An associated remote sensing technology of the high frequency radar system along the coast (coastal radar) together with passive and active satellite images can be used to follow up the movement direction of oil spill. This paper focused on two cases study consisting of 1) an event of an oil tanker ship collapsed in Ban Pramong estuary, Samut Sakhorn Province on 7th April 2014 and 2) an oil spill event at Ban Chang District, Rayong Province on 15th August 2014. For the first case, Landsat-8 had been applied and studied together with circulation pattern gained from the coastal radar and it was found that after a false color mixture by using wave range 7, 6, 4 and underline histograms equalized images it presented clearly the expected area of oil spill. The analysis was done using supervised maximum-likelihood classification in order to find a boundary and prospective of oil spill. The accuracy was evaluated by using the oil spill coordinate informed by Department of Marine and Coastal Resources comparing to the coordinate from satellite image. Its accuracy was at 82%. The second case, Radarsat-2 image in HV polarization was processed using backscatter detection of different surface roughness. The percentage of accuracy assessment that was validated from data of local government agency is 80%. For both cases, the oil film was tracked by surface circulation derived from coastal radar system. However, during the oil spill of both cases, the oil direction analysis was also reported from a related party in order to confirmed effective processing done by coastal radar system. The finding of this study was that the associated technology is deemed one of the most useful accurate and continuous data. The wide covering area of satellite images and coastal radar system will enhance confidence to monitor such event and support the ground administration with effectiveness and enhance the capability of oil pollution management plan in order to reduce the impact to coastal resources, environment and local people.
