Research on the effects of forest on river flooding in Frances's mediterranean regions has been conducted based on experiments in three catchment areas. Results display considerable differences from one area to another, highlighting the complexity of the nexus rainfall-flowrates. It should be noted that an increase in extreme flooding is far...

Carried out on granitic basins slopes of Mont­Lozère, the study relates to the genesis of the risings generated by very abundant precipitations. The stress is laid on the role, modest, of vegetable cover and on that of the permeability of the grounds.

Forest hydrology studies carried out in France have focused mainly on the Mediterranean part of the country. Three experimental catchment groups exist and have been monitored over a long period. Some forested catchments (Draix catchment) underwent no change during the study period, while others experienced either clear cutting (Lozère...
