- Abstract:
- Large numbers of landslide lake are induced by the 5·12 Wenchuan earthquake.The outburst flood will be great threat to the lives and poverty downstream if these dammed lakes breach.Research for the variable rule of outburst flood has great significance in dealing with releasing the warning and organizing the evacuation to decision-making departments.We do some model experiments to select the Zongqu dammed lake of Maoxian county as prototype model.We studied the variable rule of water level and revealed the variable rule of outburst flood by using high-definition photography cooperated with positioning a group of watermarks on reservoir area and downstream of landslide lake.We obtained the rule that the burst flow changes with time through uilibrium equation.During these processes,the breach in the longitudinal way develops in the means of heatcut erosion,while in the cross way through soil mass collapse.This result can be used as guidance for emergency risk-elimination of the dammed lake and the study of outburst flood.
