Riassunto
Summary
In
this work the role of climatic, geological, morphological and vegetational
factors in the rainfall-runoff transformation of the drainage basins is
examined. Some results of the researches focused on the impact of forests
and silvicultural treatments on flood mitigation in basins with different
physical features are shown in particular. This impact has not been
assessed with certainty by the examined studies, due both to the
complexity and the incomplete comprehension of the phenomena. The presence
of forest has proved to reduce minor floods in small basins; on the
contrary this effect has not been clearly shown for greater floods in
wider basins. As regards the role of forest operations on flood formation,
the most part of the studies shows
a slight increase of flood peaks and volumes related to the entity and the
type of the intervention.
