The impact of forest cover on streamflow has been studied in sub-Mediterranean mountain watersheds using the daily time step conceptual rainfall/runoff model GRHUM. Certain characteristics (pertaining to the soil, vegetation or atmosphere) are used to compute model parameters that describe the behaviour of the various interfaces with respect to...

The impact of a toeslope humid area upon high flows was studied in a sub-Mediterranean mountainous catchment (Peschio catchment, Mont-Lozère) using a lumped rainfall-runoff model (GR3H). The simulations were carried out at a hourly time step. The model performances and parameters were compared with those computed on an adjacent bog-free...

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.
