Constraining the Sheffield dynamic global vegetation model using stream‐flow measurements in the United Kingdom

Ghislain Picard, F. I. Woodward, Mark R. Lomas, J. Pellenq et autres

Abstract The biospheric water and carbon cycles are intimately coupled, so simulating carbon fluxes by vegetation also requires modelling of the water fluxes, with each component influencing the other. Observations of river streamflow integrate information at the catchment scale and are widely …

Scaling and assimilation of SMOS data for hydrology

J. Pellenq, Yann H. Kerr, Gilles Boulet

This paper presents a methodology to interpret and then assimilate the SMOS surface soil moisture data into a modelling framework. This methodology is designed for multiscale applications in hydrology.

Recent advances in the mechanistic modelling of forest stands and catchments

Sam Evans, Tim Randle, Paul A. Henshall, Catia Arcangeli et autres

Mechanistic approaches describing the complex processes that underpin forest system dynamics are increasingly required in order to manage forests from a multi-purpose perspective. When describing future forest dynamics the environmental implications of climate change on long-lived organisms such as trees also focus …

Soil moisture assimilation in a coupled water/energy scheme in a semiarid region.

J. Pellenq, Gilles Boulet, Anne Chaponnière, Yann H. Kerr

Soil moi sture assimilation in a coupled water/energy scheme in a semiarid region is investigated using the Ensemble Kalman Filter theory. The method is used to improve the model estimates but also to account for the seasonal evolution of the hydrologically active …
