Abstract:

Main task of this laboratory experiment was to investigate whether automatic FDR-Systems measuring volumetric soil water content in access tubes are suitable for estimation of seepage water rate. An air-dry sandy loam soil was filled 50 cm high into a column with 38 cm diameter and equipped with tensiometers and water content sensors in 5 depths. An irrigation water depth of 1600 mm was applied on the surface in varying rates for 68 days from April to June 2008. The model for estimating seepage rate from water content measurement was developed based on the law of Buckingham and the model of Mualem. The observed cumulative water flow was used for calibration. Basically it was possible to conclude from soil water content to soil water flow. During the experiment rising water content and a partly blocked water flow prevented a total match between modelled and observed seepage.
