Quantification of water redistribution along hillslopes within an endoreic sand dune system at the Agoufou local site. This dataset is part of the AMMA-CATCH eco-hydrological observatory over West Africa Monitoring of water redistribution and transfert in a sand dune system at different depths along hillslopes by manual measurements performed with portable probes (ML2 and PR2 Delta-T) during intensive field campaigns during the rainy season. Field measurements using the portable probes are performed every 10 to 15 days during the rainy season and every 2 months during the dry season. de Rosnay, P., Gruhier, C., Timouk, F., Baup, F., Mougin, E., Hiernaux, P., Kergoat, L. and LeDantec, V., 2009: Multi-scale soil moisture measurements at the Gourma meso-scale site in Mali.
