Abstract

Summary

For a better understanding of processes that influence snowmelt infiltration and runoff, and their consequences on soil erosion during spring periods, we established a long-term winter-spring ERT transect in the Gryteland catchment (Norway). The ERT transect was 71m long, with 1m spacing between the electrodes. It covered a depression with a north and south facing slope. The readings were collected once a week. Additionally, transect was equipped with six TDR profiles, to registered soil moisture and temperature, at five depths (5, 10, 20, 30, 40 cm), for quantifying the ERT readings.

The ERT and TDR monitoring gave promising results and showed the potential of ERT monitoring for understanding the soil thermal and hydraulic processes occurring during a winter and early spring. There were visible differences in temporal trends and spatial variations in observed ERT patterns on the opposite facing, which are of special interest.

Herein, we would like to present the preliminary result of ERT experiment performed during winter 2015/2016 and discuss the advantages and limitations of our experiments. We would like to stimulate the discussion about the potential of ERT for spatial and temporal monitoring of soil hydraulic and thermal processes and indirect measurements of soil water content.
