ABSTRACT
The Maaskant Recharge Project (PIM) will be the first large-scale recharge project outside the dune area in the Netherlands to use open recharge. The recharge and recovery will be managed by means of a specially installed monitoring system. There are both hydrological and qualitative aspects to this. The design of this monitoring system is based on an information analysis of the following management tasks: permit compliance, control and research. The measurement network consists of flowmeters, observation wells and water-level gauges. The observation wells are situated on different direction lines inside and outside the recharge area, their purpose being to collect information on hydraulic heads, groundwater leakage, travelling times, changes in water quality during aquifer passage, and clogging of pond beds and recovery wells. For the automated operation, some information will be collected continuously on line. In the future, the operation will be adjusted to meet new requests, requirements and conditions. In this way, the measurement system will become an evolving and integrated part of PIM.
