-Study of the lake characteristics:

  • Topographic study of the lake
  • Lake inflows and outflows
  • Bathymetric studies.

 

-Geological, hydrogeological and geotechnical field work:

  • Mapping of the dam and the lake's catchment.
  • Study of the moraines and associated risk (grain size analysis, sliding risks etc...)
  • Risk analysis of boil formation.

 

-Identification of natural hazards:

  • Landslides, block falls, avalanches...
  • Determination of the consequences of the earthquake.

 

-Geophysical investigation of the dam:

  • Electrical geophysics (ERT).

 

-Evaluation of the downstream vulnerability:

  • Determination of the human and economic vulnerability over 50 km downstream of the lake (villages, hydroelectricity, cultures...).
  • Risk mapping
