4.5 Hydrology-Discharge
According to an investigation of Weber [
6
], the Ubaye River can be hydrologically
defined as a ''Nivo-Pluvial'' regime. The results of analysis of maximum discharge
between 1961 and 2009 show that the maximum discharge happened in May 2008
with the amount of 205 m
3
/s (Fig.
4.10
).
Monthly investigation shows that lower discharge occurred during December to
March, while the maximum amount of water was recorded from April to July,
maybe as a concentrated effect of rainfall and snowmelt together (Fig.
4.11
).
