To implement into models and tools new synthetic approaches developed in water sciences and management. The environmental policies have to evalve from the qualitative and weak present state, to a more objective and transferable one, taking into account the importance of the relationships between climates, hydrological regimes, land uses...

The perspective is to build, for flood management and damage mitigation, a European methodology with
accepted standards, especially on vulnerabilities and risk maps implementations (risk = vulnerability x hazard),
which are key issues. In addition, the flood management policy must be treated with carefulness towards the
water resources and generally speaking, ecological aspects. Also because these knowledges have deep
implications in social and economic behaviour, a structured effort is made to present these new knowledges
under a "negotiable" form: negotiations for water volumes, and/or for land uses, between the different
communities and owners living all along a river.
The inondabilite methodology deals with synthetic models in hydrology, hydraulic modelling, hazards
parameters, vulnerabilities, crossed maps..., all devoted to a dynamic slowing down producing simultaneously
hazard mitigation and resources improvement with socio-economic interfaces.
A synthetic Heuristic approach will be developed, for prevention and forecasting. This methodology will be
confronted to Inondabilite, as an alternative procedure for data management, more adapted to tumbling rivers
with unstable beds.
Research will be done in the field of Regionalisation in hydrology, in the field of rainfalls, extreme rainfalls
and discharges evaluations, including reservoir management rules devoted to hazard mitigation, when water
resources are critical.
Because floods are the main structural process in water bodies, they have to be treated in priority by the
concepts set out here. To implement these concepts into models and tools, applied tests are needed.
