Scripts for calculating groundwater recharge via a stochastic vadose zone water budget

This archive contains code related to the Open Source scientific computation software GNU Octave for a stochastic vadose zone water budget. A range of groundwater recharge estimates is generated using a Monte Carlo approach based on stochastic spatiotemporal rainfall variability and empirically-derived temporal evapotranspiration variability. This project is useful for calculating the uncertainty in recharge rates due to spatiotemporal variability in rainfall and annual variability in actual evapotranspiration. Including the spatial/temporal variability in rainfall reduces the uncertainty in precipitation and therefore uncertainty in recharge for a multi-decade water budget.
