The rupture in the dyke is indicated with the arrow. On the left are shown the results of the simulation, using the DTM 
of 1966. On the right are presented the results of the simulation that used the DTM of 1997

CONCLUDING REMARKS 
  
  
In this paper are presented the first results of a research and will illustrate the approach chosen and considered useful to 
integrate knowledge of geomorphologic processes into EIA procedures. It will be a contribution to reduce the flood risk. 
3-D system analysis offers opportunities to divide geomorphologic systems into manageable elements. By linking 
geomorphology to the anthropic system, one will be able to identify the critical elements and to define those indicators
