| Zusammenfassung: | Heavy equipment used for the construction of long distance gas pipelines may cause severe and persistent subsoil compaction of arable land. In this project, the effects of compaction on the flow paths of water in the soil were studied. Water stained by a dye tracer was infiltrated into compacted and non compacted soil plots at three field sites. The distribution of the dye in the soil profiles was subsequently recorded by photographs, and digital image processing was used to analyse the flow patterns. After a geometric correction and a correction of the illumination, the colour values of the digital image were used to classify each pixel of the image as either stained or unstained. The resulting binary images, which map the area covered by the dye on the profiles were compared. We found, that the infiltration patterns responded sensitively to compaction. In many cases there was no effect of the heavy machinery on the water flow in the subsoil. This results agree with measurements of pre compaction stress and bulk density. A clear effect of the compaction on the water transport was found in the topsoil. The infiltration was reduced and the water was forced into preferential flow paths, mainly wormholes. Wetting of the main root zone decreased because the water bypassed a large part of the soil matrix. |
