This project was focus on the investigation and monitoring of environment changes after 88 Flood in Tainan. The results show that the groundwater has been polluted by the An-Ding ash landfill site, which has a large quantities of drowned pigs buried. Therefore, there is a need to closely monitor the transportation of contaminants. It has also been found that the soil around Chien-Hsing Steel factory was polluted by the petroleum hydrocarbons due to the leaking of fuel. However, the environmental quality in the reconstructed area located in Ju-Jing Township is without worry. In the aspects of disaster control and assessment, flood and mud flow was two common phenomena happened in a lot of area in Tainan. The increasing of turbidity in water resource resulted water suspending. Moreover, the contamination problems of the drowned pigs and the fuel leaking of Chien-Hsing Steel factory both resulted from the flood. In the aspects of recovery and planning about the disaster area, since the main disaster is by flood, we considered the key points in the recovery projects of floods in the last 30 years, and then give the suggestions from the points of watershed rebuilding. It focuses on the reconsideration of the 10-year-management in the easy-flood area, and the alteration of the way using groundwater. In the aspects of victim care and assistance, from the results of interviewing with residents and 101 questionnaires, the problem of flood has existed for a long time. Even the discharge of Tseng-Wen Reservoir causes the flood. The time and the way of the reservoir discharge should be reconsidered thoroughly by the government. In the aspects of building and analyzing the data system, the images collected by ROCSAT-2 satellite before and after the flood can be used as the information to set up strategies or policies.
