Appendix 12 Appendix 12.1 Typical measurement curves Following typical curves were kindly provided by Prof. Dr. Wolfgang Durner. 12.1.1 Sandy loam (Ls3) Site: Wolfenbüttel; Soil type: Slightly sandy loam. Ls3 (S 35%, U 48%, T 17%) ; Measurements in Winter 2011 "Geoökologische Labormethoden 2011", TU Braunschweig. Evaporation: 2,75 mm/d. Temperatur: 21°C 80/104
Appendix Description of the measuring process • The measurement process is typical of a clay with wide pore size distribution • The water tensions rise almost two days continuously, but at a moderate slope. This reflects large pore fraction in clay of nearly 10% • From about 50 hPa (pF 1.7), the tensiometers are far enough away to allow for the determination of hydraulic conductivities. • After two days the tensiometers are now moving with a greater slope, but still rather weak curvature continues. The measurement limit is already reached a day later. This points out a limited and simultaneously diversified porosity. • The spreading of tension values is moderate, which indicates a relatively high hydraulic conductivity in this area. • The measurement is completed by the (almost too early) failure of the upper tensiometer after three days. At the time the sample is removed about 17% water. 81/104
