This paper presents the on-going development of a generic model of a society with various sources of localized interactions with water resource. It encompasses direct interactions among agents, who are supposed to be heterogeneous: we have the aim to cover situations featuring rural / urban interdependences. It includes as well interactions between water resource and agents. These interactions depend on the quantity and quality of water present at suitable place according to the expectations of the agent. It takes in account fluxes and evolution of resource from one place to another as they may be engineered by actions of agents. Altogether it leads to represent indirect interactions among agents: the availability and quality of resource in place P1 which is meaningful for agent A1 is modified by action of agent A2 in place P2. This induces interdependence between A1 and A2. The question is then whether this interdependence is matched by other relations between A1 and A2. It is dealt with the representation of possible fluxes of information between agents. Our generic model includes an explicit representation of space and topological relations, as well as a taxonomy of possible activities performed by agents in relation with water resource. On the social side, it takes in charge frameworks of institutional analysis as formalized by Ostrom and colleagues as well as regimes of engagement, as formalized by Thévenot and colleagues.
