Assessing Mountain Soil Water Storage and Release in a Colombian Páramo With APSIS‐InSAR Data
Hydrological Processes, Volume 39, Issue 7, July 2025.InSAR detects seasonal soil swelling across a páramo ridge. Ridges swell during the wet season and lower valleys swell in the dry season. Findings indicate flow in the wet season is rapid from ridges through steep slopes and out of the catchment, whereas in the dry season lower valley sediments swell from a cumulative slower flow.
