@rarakihydro.bsky.social leads an exiting new preprint that maps dominant hydrologic processes across >14k US watersheds using streamflow signatures + ML. It’s been such fun following Ryoko and Hilary’s leadership alongside Admin, Anne and Gemma.

Thanks for highlighting Richard! It was a challenging one to write in the allotted space… the flood-drought continuum in one month. Meanwhile some colleagues in the team are working on quantifying changing hydrological transitions (water whiplash…) now and in the future.

In northern Scotland and the chalk aquifers of the south-east, river flows and groundwater levels are likely to be normal to below normal over the winter months.

💧 Winter is key for replenishment of our rivers, aquifers and reservoirs — what happens in the next three months will strongly influence whether we see drought conditions again next year.

Latest Hydrological Outlook: November river flows likely normal to above normal in northern and western UK; normal to below normal in central, southern & eastern England, plus eastern Scotland.

Groundwater levels mostly normal to below normal across the UK. This pattern likely to persist Nov-Jan.

This is a BIG DEAL!

(excuse the Trumpian capitalisation but I've been a producer & consumer of hydrological datasets over a quarter of a century....how things have come along!)

Both will be great assets to the community. Huge congratulations to the teams involved!

📣 Great news for UK hydrology!

The UK Floods and Droughts Research Infrastructure (FDRI) has announced release of two new datasets: UK-Flow15 and CAMELS-GB v2. They provide access to sub-daily river flow and hydrometeorological data across 100s of UK catchments

Most river monitoring focuses on fixed points, missing how pollution moves downstream 🌊

UKCEH’s Alex O’Brien describes an approach combining multiple survey methods to reveal how pollutants mix and travel, which is key for better water quality management.
