An experimental embankment was built in 2010 in the frame of TerDOUEST Project (reference). Treated silt and clay from the site near Héricourt in France, were used in four section approximatively 50 meters length, and 5 meters high. The first meter at the base of the embankment is buried in the soil, below the ground, to study soil-water table interaction. In this site a water table is located at approximately 1 to 2 meters depth and is registered with a piezometric probe. The last four meters of Hericourt embankment is above the ground level. The slope of this earth structure is V1:H2. One section built with the Low Plastic silt, classified A2 (NF 11-300, ref) has been treated with 2% of quick lime , and the second section with 3% of cement (CEMII). One section with the clay, considered as a Plastic Clay and classified A4 (NF 11-300) has been treated with 4% of quick lime and the second one with 2% of quick lime and 3% of cement. In each of these sections, sensors are buried at 0.25 – 0.50 and 0.75 m depth in the slope, recording simultaneously volumetric water content and suction for soil-atmosphere interactions studies. Other sensors record the volumetric water content alone in the core of the embankment, its base and the platform (Bicalho et al., 2019). All data are available from 2010 to 2020. A weather station recorded precise meteorological data from 2010 to 2013 Data paper in progress
