Dynamic water storage shapes how the critical zone functions, from sustaining vegetation to regulating streamflow and weathering. New work traces four key storage types—snow, plant-accessible water, groundwater, and surface water—and shows how shifts influence semi-arid mountain systems. 🌐🧪

James Buttle Review: Dynamic Water Storage Shapes Critical Zone Function in Snow‐Dominated Mountain Watersheds

Dynamic storage in snow-dominated mountain systems includes snowpacks, plant accessible water (PAW), groundwater and surface. We summarise recent advances in measuring and modelling these dynamic sto...

Entwässerungsgräben im Moor - die Schwimmdecken 🌱 aus Wasserlinsen sind ein zuverlässiger Anzeiger für polytrophe Nährstoffverhältnisse.

Heißt:
👉 da fließen durch die Gräben grade richtig viele Nährstoffe
in das nächste natürliche Gewässer, wo sie ökologischen Schaden ☠️ verursachen.

It's #BookWeekScotland a celebration of books & reading. #Windswept still roams the world, promoted mostly by word of mouth. This year's theme is friendship. My wee book is filled with my Highland friends - wildlife & wilderness!
So... happy Book Week and happy reading 😊

Wetlands are rare and exceptional, even small ones.

Intrinsically valuable, they also:
🌱 Offer habitat for plants, insects, amphibians and birds
🌊 Absorb stormwater, buffering against floods
🌍 Filter and reduce pollutants, improving water quality

I hear stags roaring and geese honking, and the little river singing to the sea.

Urban streams can wear a municipal fingerprint even when shallow groundwater doesn’t. In Deer Creek, heterogeneity over <0.5 km and likely deeper flow paths point to layered monitoring for infrastructure and ecosystem protection. 🌐🧪

Geochemically Heterogeneous Shallow Groundwater in an Urban Stream's Floodplain Contributes Negligible Quantities of Municipal Water Types to the Stream

Using tracers of drinking water and untreated wastewater (e.g., optical brighteners and F−), we determined that shallow groundwater within the floodplain of an urban stream was not a major contributo....
