more information on this research:
The first aim of the project is a better understanding of the complex relationship between the biomass development of the different growth forms and their resistance on water discharge at different water levels and different current velocities. The second aim is a better understanding of the effect of macrophyte cutting. Two cutting patterns on a more ecological basis will be carried out and the effects on the discharge capacity will be investigated.
The field research will be combined with an experimental approach in which both the abundance of some growth forms, and the depth and discharge of the artificial water canal can be fully controlled. This interesting combination makes it possible to extrapolate the field results over thewhole range of discharges and depths. This will be the basis for a modelling approach to plan weed-cutting schemes in an environmentally sounded way.
