Catchment Character

🌊 Mixed response A balance of quick runoff and slower groundwater baseflow.

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

Flat V weir that replaced earlier more primitive flow gauging sites (1959 - 1978) that suffered from unstable stage discharge relationship with regime highly affected by regional groundwater pumping and industrial inputs.

More detail

The catchment

Geology: mainly Triassic Sandstones with Triassic mudstones and Lower Lias to the northwest overlain by mixed glacial drift deposits. Predominantly agricultural, low relief catchment. Mixed land use.

The station

Initially rated section (1959-76), then gabion control (June 1976-Dec 1978), both very prone to weed growth leading to unstable stage-discharge relationship; now flat V weir, 15m wide with cableway.

How it measures flow

Siltation upstream and downstream of weir structure. Multiple ratings applied across period of record. Data from a acoustic doppler flow gauge located at the site was to derive the drowned flow above 0.658m. Top section was derived from high flow gaugings in 2007. Automatic system for flushing crest tapping chamber is not totally reliable. Cableway for high flows rating. Some concern over scatter in spot gaugings but this not such a problem at high flows. Fit well to recent gaugings.

Flow regime

Regional groundwater pumping for PWS and Severn regulation. Industrial effluent from Wellington and Newport; abstractions for spray irrigation. Net result only moderate.

The flow record

Bypass channel can be drained to enable work on weir, producing low or zero flows (e.g. 10 July 2003). 2011 flows higher than normal due to Shropshire groundwater scheme running in June. Full period of record peak flow data reviewed and released in September 2019 (WINFAP Files v8).

Frequently asked questions

Is the River Tern at Walcot flooding today?

The current level is 0.39m, which is within the typical range of 0.39 to 1.30m. Flooding is unlikely at this level.

Is the river level rising or falling at Walcot?

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 Tern at Walcot?

The typical range at this station is 0.39m to 1.30m, based on Environment Agency historical data. Levels above 1.30m 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.
