Schäfertal
The Schäfertal , also Schäferbachtal or Schäfergrund , is the valley through which the Schäferbach , a tributary of the Selke , flows.
description
The mean terrain gradient is 3.5 °. The valley begins at Fitzgeroder Heimberg, about one kilometer east of the stream source, and extends to the mouth of the stream in the Uhlenbach . It has the shape of a Mulde valley and is located north of Siptenfelde . The valley in the Harzgerode area is part of the Harz landscape protection area .
Another stream flows about 1 km north of the Schäferbach, almost parallel to it and, after a damming 150 m before the mouth, also flows into the Uhlenbach.
The highest point is 474 m above sea level. NN . The Schäfertal lies in the main leeward area of the Harz , with westerly winds prevailing. The mean annual rainfall is 630 mm / a, the mean annual temperature 6.9 ° C (1973-2010). The climate is slightly continental with low air temperatures in winter (winter 2002 –20 ° C, 2003 –24 ° C) and night frosts occurring from early autumn to late spring. It is possible for snowmelts to occur several times within one winter.
The maximum valley width of approx. 800 m is reached roughly in the middle of the stream. Para brown earth is the predominant soil type . The area is primarily used for agriculture (mainly grain cultivation). Since the Schäferbach does not have enough water, some of it is brought in from the Uhlenbach. About a tenth of the area is covered by grassland (mountain meadows), less than 5% by forest (almost entirely spruce forest). In addition to the Harz High Road , which crosses the southwestern edge of the valley, there are only unpaved supply routes for agriculture in the valley. Most of these are located south of the Harzhochstrasse, with only two paths crossing the stream (as of 2000).
Hydrological investigations
The valley has already been the site of hydrological investigations in many cases. To this end, it was equipped as a test area for the Magdeburg School of Water Management (today Magdeburg-Stendal University of Applied Sciences , Department of Water and Recycling Management ) as a test area. Continuous measurements have been carried out in the hydro-meteorological measuring garden since 1968. The representative area Schäferbach (hydrological study area) extends from Fitzgeroder Heimberg to 1.755 kilometers of flow. The river and lake landscapes project area of the Helmholtz Center for Environmental Research works closely with the water and recycling management department at Magdeburg / Stendal University of Applied Sciences. Thereby u. a. Investigations were carried out on the surface and lateral P-flows from the catchment area into the water body. The department for hydrology and water management at the Christian-Albrechts-Universität zu Kiel is also involved in the research .
