Waterschap Groot Salland

Waterschap Groot Salland (NL) is located in the centre of the Netherlands and involved in the agriculture pilot. To prevent and reduce damage to agricultural production, the authority plans to implement an innovative system for managing one of its catchment areas in a more efficient manner. Given the projected increase in both periods of droughts and extreme precipitation, the authority will implement an innovative remote-controlled steering mechanism that is linked to weather forecasts in one of its catchment. The focus is on an area called ‘Streukelerzijl’ for which a new catchment has to be created in response to floods in 1998. The water from the new catchment area will be drained by two structures in the catchment itself and one pumping station at the Vecht river. Both structures (weir and pumping station) and the pumping station will be double-acting: they will be used for discharging and supplying water to and from the Vecht river. To manage this management system, a remote-controlled weather-forecast based steering mechanism will be placed at the pumping station. However, since a provincial road will be relocated, the location of the pumping station is yet unclear. Therefore, in the DROP project the authority will only start testing the steering mechanism at one of the double acting structures. Until the pumping station is finalized, water will be transported via another watercourse.

Pitch of Wilgert Veldman – projectleader

The following actions are foreseen as part of the DROP project:

  • Realization of two double-acting structures (weirs and pumping stations)
  • Design and testing of an innovative steering mechanism that allows for quick and effective responses of the system to weather changes. Testing will be done on one of the double-acting structures.
  • Design of a double-acting pumping station (inlet/outlet) near the Vecht river on which the steering mechanism will be implemented eventually.

 The agriculture pilot is implemented with the Flemish Environmental Agency (Belgium). Drought experts of both organizations participate in six exchanges during which potential measures are designed, discussed and evaluated. The governance team of the DROP project will visit the region twice to define and evaluate the regional governance setting for drought adaptation measures.
