Forest water balance model
- Silva Joint Research Unit
The exceptionally severe water deficits in 2003 and more recently in 2018 highlighted in particular the emerging need to be able to quantify intensity and severity levels of water deficit occurring in forests. It became clear that forest managers lacked the necessary diagnostic tools to further understand major water fluxes in forest ecosystems. These tools would allow them to quantify the respective impacts of climate, soil type and management techniques on water availability for trees.
BILJOU users also will be able to perform real time simulations of operating water stands in observed climate conditions. This tool also will allow them to create test scenarios for susceptibility studies on forests and/or climate to gauge the water consumption levels of forest stands and the intensity and recurrence of drought events.
BILJOU users will also be able to consult pre-calculated drought maps for metropolitan France for a large number of typical stands. Depending on the user's interest, he can build his query and consult on map the characteristics of droughts in absolute value and in anomaly.
