The water information system: Multiple aims

The WIS-F / Aims / Data availability / Users

Today, the WIS-F collects data on rivers and lakes, coastal waters and groundwater. It covers all of continental France, the main overseas territories and Mayotte. Major elements in the system are designed to meet three main goals.

1. Obtain knowledge on water resources and aquatic environments.

Status of aquatic environments.

Users can access different types of data, quantitative (river flow rates, levels of lakes and aquifers), chemical (on nitrates, phosphates, concentrations of heavy metals, pesticides, etc.), physico-chemical (oxygen, salt, acid levels, etc.), biological (on fish, invertebrates, endangered species, aquatic plants, etc.).

This part will soon be enhanced with data on river temperatures and morphology (hydrological regimes, obstacles to ecological continuity, types of banks) and on river and lake habitats.

Data on coastal waters and groundwater are already fairly well organised in national data banks, but the data on continental surface waters are still highly fragmented and scattered in a number of river-basin databanks or even on more local levels. That is why Onema, via the WIS-F, has undertaken a vast and complex project to collect all the data on continental surface waters, whether chemical, physico-chemical, biological or hydromorphological, in a national databank on water quality that will be folded into the WIS-F.

2. Assess the pressures exerted on aquatic environments and the consequences.

Human activities and their impact on environments.

Users can access data on fish (counting operations for fish populations), pollution (effluents of water- treatment plants, etc.) and its consequences (eutrophication of rivers due to nitrates released to the environment). As of today, this data is still highly fragmented and uneven. A particular effort must be made to provide long series of more complete data and to enhance the data on household, agricultural and industrial pollution, whether accidental or diffuse, as well as on the water drawn for agricultural irrigation, industry and residential needs.

3. Guide and evaluate public policies designed to protect and restore aquatic environments.

Solutions to protect and restore aquatic environments.

Users can access data on regulations, on management tools for planning and development work, and on inspection programmes. A great deal of information is available, but training on how to use it must still be set up.
In addition, users can also access economic data and information on public water and sanitation services. A databank with structured data on water and sanitation services (service quality, performance indicators, etc.) is currently being set up and will be included in the WIS-F.

All the data, supplied by numerous data producers, is freely accessible on the Eaufrance site that is organised in a number of theme-based internet portals. It represents a wealth of data (spanning over a century for the hydrometry data) that must be saved, notably for future use in understanding and simulating certain changes in the environment.
