Abstract:

This dataset presents a total of 4817 boreholes that intersect the alluvium at the bottom of the main valleys within the Seine River catchment, mapped based on geological maps at 1:50 000 scale (Pomerol and Monciardini, 1992; Janjou, 2004; Quesnel et al., 2008). The boreholes were extracted from (i) the BSS (Base du Sol et Sous-sol) database available on the French Geological Survey (BRGM) website (http://infoterre.brgm.fr/) and (ii) data available in the literature (Lefebvre et al., 1974; Pomerol and Morciandini, 1992; Krier, 2004; Chourio- Camacho et al., 2024). Each borehole was manually analyzed to ensure consistency between data. This dataset contains the following information: (i) geographic position of each borehole using both WGS84 and the RGF Lambert 1993 projection, (ii) elevation at the bedrock-alluvium interface, (iii) a description of the alluvium such as total alluvial thickness, alluvial facies description, depth and thickness of each individual alluvial facies, (iv) bedrock characteristics such as lithology, geological formation and age, (v) valley location (Chourio- Camacho, 2024) and (vi) total of facies for each borehole, date of drilling, the data provider and the link to data. Our dataset has numerous applications in geomorphology and hydrology. It allows estimating the geometry of the alluvial infill and reconstituting the geometry of the top of the bedrock substrate or quantifying the sediment volume storage along the valley bottoms of the Seine catchment.
