ABSTRACT
The aim of a drought plan is to prepare contingencies for drought conditions. Groundwater is part of that plan which needs to promote sufficient baseflow to small rivers and their associated wetlands. A methodology was developed which comprises:
preliminary hydrogeological and ecological investigations to identify priority basins;
definition of correlations between minimum river flow and piezometric levels;
selection of reference piezometers;
determination of piezometric thresholds for imposing limitations or suspending the use of water.
The Beauce aquifer management strategy is used as an example.
