Deltares (an important water management practice oriented research institute), the
province of Overijssel, the farmers union (LTO-North), the drinking water company
(Vitens) and Landscape Overijssel, the nature organization. In this report the
problematic is analysed and a score of potential measures in the water system
identified. The DROP pilot projects in the Twente region of Vechtstromen are
related to the kind of measures proposed in the report. They consist of seven local
implementation projects with an impact on the water system and two investigations.
Also, two research projects were part of the activities in DROP. Finally, water
management plans were developed with 15 farmers. The projects are carried out in
the programme “Water Collective Twente”. In fact this programme is a follow-up
of two similar previous programmes: “Back to the source” and “Upgrading Water
Management for Agriculture”. Also in these programmes, like in the present one,
collaboration and exchange with neighbouring water authorities took place.
9.3.2.1 Implementation Projects
Several implementation projects were realized in the northeast of Twente: drainage
systems were removed, ditches were muted (sometimes with sand nourishment, see
Fig. 9.2), streams were shoaled and water storage areas were constructed. Drainage
systems are typically geared towards getting rid of the water as soon as possible.
Deep ditches and creeks have a similar effect of nearby land: they extract
groundwater from the shores with also some effect on ground water levels further
