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. 52.277090733815,6.1621209807533 Sander Verheijen 0.1 - 1.0 m³/s ,, ,,, 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. 26187 Complete The Zandwetering is a slow flowing waterway in the urban area of Deventer and the countryside to the north. The latter, downstream part of the waterway is characterized by meadows, fields and woodland. Its natural hydrological regime has been altered by withdrawals for agricultural purposes and by water level regulating structures. As a consequence, development of vegetation, macroinvertebrates and fish have been held back. 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 at six locations below the water line to create narrower stretches in the stream. This measure was carried out along with other measures, such as the creation of fish passages. This page focuses on the introduction of dead wood.
