Abstract

This study focuses on the analysis of soil physical properties (top soil texture) and soil states (temperature and soil moisture content) using geophysical data (gamma-ray spectrometry and electromagnetic induction - EMI). The study is part of the EU-FP7 project Ludwig et al. (2010), focused on the analysis of climate change impacts on the hydrology of Mediterranean basins. Process-based hydrological models require numerous soil and vegetation parameters in an appropriate spatial and temporal resolution. Although it is known that the response of those models is sensitive to the quality of soil data, adequate soil information is missing in most cases. In order to improve the quality of soil property prediction on the one hand side and to reduce uncertainty on the other, the applicability of non-invasive mapping techniques has to be tested. In a cross cooperation between the FP7 projects CLIMB and iSOIL, the UFZ Helmholtz Centre for Environmental Research participated in a field campaign in the study area in October 2010. The site of the presented study is located at the S.Michele experimental research farm in the Rio Mannu Catchment (Southern Sardinia).
