Short summary
Soil strength is influenced by wetness conditions, affecting slope stability, agricultural productivity, etc. Monitoring soil moisture is essential for risk management. We used Distributed Acoustic Sensing to monitor the deformation of a grass-covered slope over two summer months. We observed both long-term drying and daily "breathing" cycles: nighttime swelling and daytime shrinkage. By integrating strain and soil moisture data, we provide new field-scale insights into soil strength evolution.
