Influence of agricultural timber plantations on neighbouring watercourses

Research work has begun in Peickwitz, Colmnitz and on the Mortelbach stream

Since May 2021, the TU Dresden has been running measurement campaigns on the watercourses and in the agricultural wood structures in Peickwitz, Klingenberg-Colmnitz and on the Mortelbach near Waldheim. In two rounds (vegetation period 2021 and 2022), different parameters will be investigated that describe the functions and services of agricultural wood structures for the flowing water ecosystem.

At the Peickwitz site near Senftenberg, an agricultural wood plantation with the poplar species Fritzi Pauley was planted along the Peickwitz millrace to reduce wind erosion. Directly adjacent to the Wiesengrundbach in Klingenberg-Colmnitz is a 0.8 ha agrowood plantation (a so-called variety garden with poplar and willow trees), which is used as the second pilot area in the measurement campaign.

The following parameters are included in the analyses:

  • Water level h [m].
  • Flow velocity v [m/s]
  • Flow rate Q [m³/s]
  • Water temperature T [°C]
  • Terrain [m a.s.l.]
  • Location of woody plants
  • Air temperature and humidity
  • Soil water content
  • Radiant heat of the sun
  • Circumference of tree trunks
  • Leaf sprouting and leaf fall
  • Rainfall
  • Leaf area index
  • Tree structure (laser scan 2x per year)
  • Vegetation development
  • Soil properties
  • Wind speed
  • Solar radiation
  • Air pressure

In addition, the team from the Department of Hydraulic Engineering at the TU Dresden is conducting macrozoobenthos (microorganisms in flowing water) sampling on the Mortelbach in the district of Mittelsachen in order to be able to make statements about water quality and temperature development. 

As soon as the first results and series of measurements are available, we will publish them on this website.
