• Retrieving root-zone soil moisture from land surface modelling and GRACE/-FO and validating its dynamics with in-situ data over West Africa (2026) · Hydrology and earth system sciences · doi

  The study identifies a research gap in the understanding of root-zone soil moisture dynamics. The study notes that prior work has focused on surface soil moisture, while research on root-zone soil moisture remains limited.

• Interpretable soil moisture prediction with a knowledge-guided deep learning approach (2026) · Hydrology and Earth System Sciences · doi

  The nonlinearity of soil water transport, variability in boundary conditions, and the intricate nature of soil properties contribute to strong spatio-temporal variabilities in soil moisture dynamics. Traditional physically based models have limitations in capturing these complexities.

• NMR-based characterization of soil-water characteristic curves considering volume change during drying-wetting cycles (2026) · Bulletin of Engineering Geology and the Environment · doi

  The gap is the lack of understanding of the effects of drying-wetting cycles on the soil-water characteristic curve. The paper identifies the need for a multiscale experimental methodology to investigate the soil response upon multiple drying-wetting cycles.
