Due to climate warming in the recent decades,moraine-dammed lake outburst hazards are increasingly threatening people and property.Great progress has been made on the researches on the moraine-dammed lake outburst hazards,because they become a wide and intensive focus.The researches on moraine-dammed lake hazards experienced the processes from field survey for typical moraine-dammed lakes to remote sensing combined with field survey in large-scale regions,from qualitative,semi-quantitative calculation to quantitative computation,from empirical formula based evaluation to simulation based on physical mechanisms.This paper begins with the identification and variation detection,and summarizes the current studies of the causes and mechanisms of moraine-dammed lake outburst;the assessment index systems involved the morainedammed lake outburst risks,the possible simulation ways for moraine-dammed lake outburst floods and debris flows,and their mitigation measures.In the end,the paper outlines the prospects of the researches on moraine-dammed lake outburst hazards,i.e.,1) using remote sensing combined with field survey so as to make the assessment from qualitative to quantitative,2) using multi-measures with multi-data sources in order to simulate the moraine-dammed lake outburst hazards systematically,3) using mitigation techniques integrated with humanity environment factors to remedy the outburst hazards.
