Glacial lakes pose a significant threat to any socioeconomic activities located in the downstream reaches of high mountain valleys. The impact of the landslide or ice blocks into the lake as well as the collapse of the highly unstable moraine dam may produce glacial lake outburst flood (GLOF). Many methods were designed to assess the risk of GLOF and the results of such assessments are very useful for local decision makers in high mountain regions. These methods are more or less simplified due to the limited source of data. That might be the reason of the lack of complex studies of factors causing and influences contributing to the final GLOF origination and their interconnections, not mentioning precise quantification of these factors and other influences. Thus, the objectives of this Ph.D. project are as follows: 1) the analysis of the documented former cases of glacial lake outbursts; 2) the identification of factors and influences of GLOFs and detailed mathematical analysis of their complex interconnections; 3) the identification of key factors and their respective thresholds with use of results of various related fields of study (e.g. physics); 4) the creation of a new method and its verification on both real cases of GLOFs and mathematical simulations. The project solution will combine geographical and mathematical methods, therefore candidates experienced in both fields are particularly welcome.
