Finely tuned process-based tree-growth models are of considerable help in understanding the variations of biomass increments measured in the dendrochronological series. Using site and species parameters, as well as daily climate variables, the MAIDEN model computes the water balance at ecosystem level and the daily increment of carbon storage...

Patchy landscapes driven by human decisions and/or natural forces are still a challenge to be understood and modelled. No attempt has been made up to now to describe them by a coherent framework and to formalize landscape changing rules. Overcoming this lacuna was our first objective here, and this was largely based on the notion of Rewriting...

We consider discrete qualitative models of ecosystems viewed as collections of interacting living (animals, plants..) and nonliving entities (air, water, soil..), whose conditions of appearance/disappearance are controlled by a set of formal rules (i.e., processes). We present here two methods to statically analyze models. The first one is used...

In this paper we consider discrete qualitative models of ecosystems viewed as collections of interacting living (animals, plants.. .) and nonliving entities (air, water, soil.. .), whose conditions of appearance/disappearance are controlled by a set of formal rules (i.e., processes). We present here a rule-based method allowing to compare...

Haiti, a Caribbean country, is highly vulnerable to hydroclimatic hazards due to heavy rainfall, which is partly linked to tropical cyclones. Additionally, its steep slopes generate flash floods, particularly in small catchments. Moreover, the hydrology of this region remains poorly understood and understudied. Unfortunately, there is no...

Haïti, pays caribéen, est extrêmement exposé et vulnérable face aux aléas hydro-climatiques. Or, aucune base de données hydro-climatiques exploitable et facilement accessible à la communauté scientifique n'existe. Les seules données existantes sont les 156 séries de pluies mensuelles (1905-2005) et les 70 séries de débits journaliers...
