     292 points with an up_catchment_area >40000 and a st_cs_largeurlameeau very small (<15).[[BR]] 
     30View with the up_catchment area >40000 - they correspond to the riversegement with the maximal higth, so the problems don't come from the calculation of the up_catchment_area, but when we join the CCM layer and the BDMAP points.[[BR]]
