🏞️ The River as a Time Machine
Travel 350 kilometres downstream to Gloucester and the same water — the same River Severn — is almost unrecognisable. Here it moves in great, lazy loops across a perfectly flat floodplain. It is wide and deep, carrying not boulders but invisible particles of fine silt. The valley walls have vanished, replaced by a broad plain of fertile farmland that floods every winter. The river looks almost asleep.
Same river. Same water. Utterly different landscape. The River Severn is a time machine — every kilometre downstream shows you what thousands of years of geological work looks like. From source to sea, erosion gives way to transport gives way to deposition. Understanding that journey is the entire story of this topic.
