Description :
A mathematical model can be used to simulate the effect of a variation in forest cover on snowmelt runoff and provides important data for basin management. Simulations with the CEQUEAU square-grid system model on a >3000km basin confirm the possibility to modify snowmelt synchronization between different parts of a basin by changing the distribution and/or percentage of its forest cover. In the given example, if the forest cover had been distributed uniformly so as to occupy 50% or the total area of the basin, the maximum runoff would have been reduced by approximatively one third, whereas a complete deforestation over 670m would have led to a larger maximum runoff.
