      abstract     = {The effects of land use change on the occurrence and
                      frequency of preferential flow (fast water flow through a
                      small fraction of the pore space) and piston flow (slower
                      water flow through a large fraction of the pore space) are
                      still not fully understood. In this study, we used a five
                      year high resolution soil moisture monitoring dataset in
                      combination with a response time analysis to identify
                      factors that control preferential and piston flow before and
                      after partial deforestation in a small headwater catchment.
                      The sensor response times at 5, 20 and 50 cm depths were
                      classified into one of four classes: (1) non-sequential
                      preferential flow, (2) velocity based preferential flow, (3)
                      sequential (piston) flow, and (4) no response. The results
                      of this analysis showed that partial deforestation increased
                      sequential flow occurrence and decreased the occurrence of
                      no flow in the deforested area. Similar precipitation
                      conditions (total precipitation) after deforestation caused
                      more sequential flow in the deforested area, which was
                      attributed to higher antecedent moisture conditions and the
                      lack of interception. At the same time, an increase in
                      preferential flow occurrence was also observed for events
                      with identical total precipitation. However, as the events
                      in the treatment period (after deforestation) generally had
                      lower total, maximum, and mean precipitation, this effect
                      was not observed in the overall occurrence of preferential
                      flow. The results of this analysis demonstrate that the
                      combination of a sensor response time analysis and a soil
                      moisture dataset that includes pre- and post-deforestation
                      conditions can offer new insights in preferential and
                      sequential flow conditions after land use change.},
