Catchment Character

🌊 Steep & flashy Steep catchment sheds rain quickly — expect fast, sharp rises after heavy rain.

Your catchment is all the land that drains rainfall into the river above this gauge. Its character — how steep, wet, wooded, urban or chalky that land is — decides how fast rain here turns into a rising river. A steep, bare or clay catchment is “flashy” (rises and falls quickly, floods easily); a flat, chalk or well-wooded one is slow and steady. The tiles below put numbers to that; the flow-duration curve reads left-to-right from the river’s typical high flows (Q5) down to its low flows (Q95) — a steep curve means a flashy river.

About this gauge

Crump profile Flat V weir from 1992 that replaced velocity-area station with natural rock step control approximately 150m downstream of cableway.

More detail

The catchment

High relief headwaters and broad bottomed valleys of moderate slope with Boulder Clay and fluvial gravel. Solid geology predominantly Ordovician slates and shales. Land use: moorland, forestry and pasture.

The station

From Feb 1992 Crump profile Flat V (1:20) weir, 12.4m wide, 0.72m high wing walls, replaced velocity area station with natural rock step control approx. 150m d/s of cableway. Gravel bed. Right bank floodplain approx. 50m wide, partially crossed by cableway.

How it measures flow

Cableway rated. Right bank floodplain approximately 50m wide, partially crossed by cableway. Two ratings applied across period of record, the most recent is valid from April 1992 when weir installed. Ratings fit well to corresponding gaugings post-1992. Theoretical rating on open channel pre-1992 means flows are highly uncertain, although fit to available gaugings in the peak flow range is within acceptable tolerances.

Flow regime

Sewage effluent has insignificant effect upon flow regime.

The flow record

Water year 1991/1992 rejected due to the true AMAX occurring during a missing period. Full period of record peak flow data reviewed and released in August 2021 (WINFAP Files v10).

Frequently asked questions

Is the River Tanat at Llanyblodwel flooding today?

The current level is 0.15m, which is below the typical range. Flooding is very unlikely at this level.

Is the river level rising or falling at Llanyblodwel?

Based on the most recent readings, the level is currently steady. The chart above shows the last 7 days of measurements, updated roughly every 15 minutes.

What is a normal level for the River Tanat at Llanyblodwel?

The typical range at this station is 0.23m to 1.05m, based on Environment Agency historical data. Levels above 1.05m are higher than usually seen and may indicate a flood risk.

How often is this river level data updated?

Readings are taken by the Environment Agency gauge roughly every 15 minutes and FloodRadar refreshes its data continuously, so the level shown is normally less than an hour old.
