Glacial lake boundary susceptibility to failure is a geotechnical aspect.
What are the approaches taken for geotechnical modelling of moraine dams/rock dams/ice dams and surrounding rock/moraine failure that can profoundly contribute towards initiation of GLOF!
Approaches to model possible debris flow associated with GLOF!
Surrounding rock/moraine/ice structure that could fail and fall into the reservoir of a glacial lake can also initiate GLOF, or sometime without failure of lake boundary, splashing out waves as a result of the failed mass into the lake can create havoc downstream.
Available or intended research approaches towards consideration of these geotechnical aspects and modelling of the strength/stress conditions of lake vicinity in view of glacial lake hazard is aim of this discussion.
Hello
modelling in this field is claiming for different skills and input data: geomorphology, climate conditions, historical development, geotechnical properties, debris evolution after local collapses etc.

I found many interesting features well developed.

Claudio Oggeri Thank you for taking time with the follow up and sharing details.
Two approaches are common to model a moraine dam failure i.e., overtopping and piping. These two failure modes need data on bathymetry and geotechnical parameters of a moraine dam. Selection of failure mode must be based on rigorous field work as well as historical data on dam failures in the study area if any.
In the Indian Himalayan region, modeling of avalanches and debris flows requires a perfect and fine resolution terrain data. Such type of terrain data is not available till date. Further, researcher can create a fine resolution terrain but it requires huge amount of funds.
