Rapid flowing hazards
Rapid flowing hazards
 
 
 

We assess hazard and risk, model hazard scenarios and implement prevention measures, such as monitoring and early warning  for a variety of rapid flowing hazards, such as mud and debris flow, flash floods, glacial lake outburst floods (GLOF) and snow avalanches.

Rapid flowing hazards are frequent in mountainous areas, and are often associated with heavy rainfall, snowmelt, and environments undergoing deglaciation. Our end-to-end prevention measures act to increase levels of safety for exposed communities.

 
 

Monitoring of a landslide causing debris flows, which flow several kilometres to the valley below. The mobile monitoring system consists of a portable radar interferometer and time-lapse lidar, which can be quickly operational to measure landslide activity in a crisis situation.

 
 

A displacement map derived from radar remote sensing, uniquely showing the process of landslide failure, and the initiation of a debris flow. The displacement rate shown is 1.9 cm per minute.

 
 

Assessing hazard, through combined field study and remote sensing (e.g. field monitoring), we acquire necessary input data for constructing hazard scenarios. In this case, a runout trajectory analysis, however such models also provide information about inundation depth, energy and velocity, which are used to formulate various hazard and risk maps.
