Document prepared by an Inter-service Mission for Water (MISE), the regionalized operational action plan (PAOT) plans the field actions to be carried out to implement the programme of measures and thus reach the targets set out in the
Any system which, by measurement, observation or any other method, can acquire knowledge data on: aquatic environments, water resources and uses, pressures (and associated impacts) exercised on the environments and resources, and related economic data. It may be monitoring networks, surveys (water prices, economic activities), inventories (wetlands, lakes, flood-risk areas, protection perimeters ...), etc.
Estimate of the balance between, on the one hand, abstractions and needs related to supply inputs to surface water, and on the other, the natural recharge of groundwater. The quantitative status has two classes: good and poor. Good quantitative status of groundwater is achieved when abstractions do not exceed the turnover capacity of the available resource, taking into account the necessary supply inputs to surface water ecosystems, directly dependent sites and wetlands.
Action to rehabilitate a more or less artificialized environment to its original and natural status. By trying to rehabilitate all the physical characteristics of the environment (e.g. meanders recovered in an improved river), revitalization aims to recover all the initial potentials of the environment in terms of biological diversity, self-cleaning capacity, etc. Most ambitious than restoration, revitalization aims to globally recreate the ecological functioning and
Deposit of fine particles in the interstices of a porous medium (soil) with the effect of decreasing its permeability. The intensity of silting can be variable: "Nil" if there is no silting, "Low" if there is partial silting on one type of substrate alone (gravel, sand), "Medium" if the silting does not affect all habitats or "High" if the silting is widespread.
