Abstract
    Hydrogeological interventions in ecologically valuable areas must be well studied beforehand. Modelling of these interventions based on field observations and field studies is herein a valuable step. This is illustrated with an example in the western Belgian coastal plain. A new drainage system had to be designed for the preservation of the archaeological excavation site ‘OLV Ten Duinen’. This site is situated in a valuable and protected dune area. A system of pumping and deep infiltration of water was studied to optimise the draining of the site but to minimise the effects in the nearby dunes. A double pumping test was used to derive the relevant parameters. These were then used to simulate and find the optimal configuration of the extraction and deep infiltration wells.
