above the maximum water elevation therefore the safety is not to be concerned. Especially, the RCC block that seen some cracks is the part that not related with the stability of the dam. Fig. 5 Active Faults and Earthquake Epicenter near the Dam Site Even though the dam is performed well according to the engineering evaluation, however the people who lives downstream of the dam are very concerned about the safety of the dam. This is because they thought that the cracks of the concrete covered of the RCC block may lead to the leakage just like what they had experienced before. The concerns became a panic and serious since the community required that the dam shall be removed. Several meetings were set up to discuss about the practical solution and the consensus are to keep the water storage to be lower than 60% until the dam has been fully repaired. 4. EMERGENCY ACTION PLAN However, people at the dam downstream still worried over the incident. Besides, there was not any study, plan, prevention measures or risk surveillance in terms of surplus discharge and dam break, which caused faster flood and more damage to life and property. Then, the Royal Irrigation Department had studied the dam break of Mae Suai Reservoir Project in terms of surplus discharge, causes of damage of dam and appurtenant structures which may cause flood and flood severity and characteristics, as well as to complete action plan to cope with the dam break. 886
