In this work, we numerically study laminar flows in forced convection in a U -shaped channel. Our study was based on a finite volume method by the fluent code carried out for a Reynolds number varying in the range 100<Re<700, and the Rayleigh number Ra=105 and Prandtl number Pr=0.72. As a function of the Reynolds number, the results obtained are pr...

Abstract Woody plants play a major role for the resilience of drylands and in peoples' livelihoods. However, due to their scattered distribution, quantifying and monitoring woody cover over space and time is challenging.

From in situ measured woody cover we develop a phenology driven model to estimate the canopy cover of woody species in the Sahelian drylands at 1 km scale. The model estimates the total canopy cover of all woody phanerophytes and the concept is based on the significant difference in phenophases of dryland trees, shrubs and bushes as compared to tha...
