Multi-year monitoring data of subsurface water conditions for Dutch canal dikes
What's in it
This dataset has been updated with measurements of hydraulic head, soil moisture content, soil temperature and soil salinity up to March 2025. This dataset consists of subsurface water measurements (soil moisture and hydraulic head levels) from a monitoring network for canal dikes with different characteristics in the western Netherlands. Subsoil and geometric information of the canal dikes and meteorological data is made available as well. The first three years of measurements, from spring 2020 until March 2023, and site-specific information are made available. The data include two extremely dry summers (2020 and 2022).The following data are made available:Soil moisture content, soil temperature and soil salinity data (time series)Hydraulic head data (time series)Local rainfall and potential evaporation (time series)Cross-sectional profile (elevation profile from survey)Bore profiles and soil characteristics data (soil description and laboratory) The network monitors soil moisture and soil temperature in the unsaturated zone at every dike with 10-12 sensors at every location, with additional information about salinity in the crest of the dike. The sensors are installed at …
