Near surface geophysical data (Electromagnetic Induction and Electrical Resistivity Tomography) from the Ahr floodplain at Mayschoß, Germany

The dataset was used to explore the spatial distribution of fluvial deposits in the area of the Ahr valley floor southwest of Mayschoß. The objective of this investigation was to extrapolate the findings of a chronological classification of an embedded floodplain cross-section, thereby underscoring the significance of fluvial geomorphological records in reconstructing past high-magnitude flood events. In detail, we used geophysical prospection methods (Electromagnetic Induction and Electrical Resistivity Tomography) to map the distribution and thickness of floodplain sediments as both methods provide proxy information on grain size distribution.

本数据集旨在探究梅绍斯（Mayschoß）西南侧阿尔河谷谷底区域内的河流沉积物空间分布特征。本次研究的核心目标为对某一埋藏河漫滩剖面的年代学分类结果进行外推，借此凸显河流地貌记录在重建历史强洪水事件中的重要科学价值。具体操作中，本研究采用地球物理勘探方法（geophysical prospection methods），包括电磁感应法（Electromagnetic Induction）与电阻率层析成像法（Electrical Resistivity Tomography），对河漫滩沉积物的分布与厚度进行填图；上述两种方法均可提供沉积物粒度分布的替代指标信息。
