|Project summary=The water authority has made an attempt to create more variation in morphology and flow structure of the Marswetering and Zandwetering by introducing dead wood in the stream. The wood was introduced below the water line to create narrower stretches in the stream.
|Monitoring surveys and results=The effect of the measures on the abundance of macroinvertebrate and fish has been monitored. The experiments did not yield any favourable results, probably because the selected streams have a rather low discharge and are therefore less suitable for this type of measures.
|Lessons learn=Although the method yielded no results in this particular location, it has since been applied in various other projects and is generally well received by society. An important lesson is that a sufficiently high discharge is required for this measure to function. Projects such as this one can be complicated by a shortage of available wood and problems cleaning out debris. It has also been noticed that willow wood is less suitable for this measure, as it degrades quickly and is likely to sprout.
