Decadal in situ hydrological observations and empirical modeling of pressure head in a high-alpine, fractured calcareous rock slope Abstract. In peri- and paraglacial regions, water plays a critical role in the hydrological cycle and slope stability. However, hydrological models often overlook water infiltration into bedrock due t...

Great to see this out out! 👍🙌 well done @joshwolstenholme.bsky.social 👏

Hydrology Paper of the Day @egu-esurf.bsky.social on how climate affects river flooding, sediment transport and geomorphology: the subarctic-nival Pulmanki River; decades of hydrograph analyses and event classification; sediment modelling and transport; and increases in double-peaking flood events.

Apologies for the glut of new paper posts thanks for your patience 👏👍
