Abstract
The M s 8.0 Wenchuan earthquake produced 257 landslide lakes along the faults and rivers. The outburst risk of the lakes was successfully relieved by emergent risk analysis and response treatments. This paper briefly reports the activities of risk reduction based on remote sensing data and field surveys in the study area. For the purpose to recognize and reduce the risk of landslide dammed lake, the formation process of landslide dam has been analyzed using the method of numerical simulation. Four indexes were chosen to perform a quick evaluation of risk, including dam structure, dam height, maximum water storage capacity, and size of the population in potentially affected area. The evaluation results have been successfully applied to emergency treatment of dammed lakes such as the Tangjiashan dammed lake, the largest landslide-dammed lake resulted from the earthquake that has the highest risk of outburst and various scenarios of potential failure were analyzed. From the success of risk reduction of Tangjiashan dammed lake, lessons have been learnt to farther understand the risk management and develop effective countermeasures for risk reduction, based on which a research proposal is suggested.
