The project aims for an interdisciplinary approach using 4D time-laps Electrical Resistivity Tomography in archaeological prospection. Unlike traditional methods, which rely on single-instance geophysical data, our method uses repeated imaging to monitor changes in subsurface resistivity due to varying moisture conditions. Year-long surveys in the Czech Republic and short-term surveys in Germany will assess how resistivity anomalies related to a wide range of archaeological features vary with precipitation and seasonal moisture fluctuations. Validation through ground-penetrating radar, excavations, and soil core analyses will improve our understanding of the behaviour of earth materials. The goal of this project is to improve the interpretation of archaeological features and optimize the timing of resistivity measurements. By combining natural sciences and archaeology, our research seeks to minimize the need for excavations and support the preservation of cultural heritage.
