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

Sidelooker horizontal ADCP, using index velocity method to derive flows from 15/02/2008 onwards. Velocity Index gauge replaced multipath cross-configuration Ultrasonic Time of Flight gauge in 1991. Prior to 1991, gauge had a non-operational velocity-area rating which was not suitable to process flow due to being subject to variable backwater influence of the River Derwent and weed growth.

More detail

The catchment

Large catchment which contains much of Birmingham City. The Trent headwaters have small outcrops of Coal Measures whilst the Dove catchment is dominated by Millstone Grit and Carboniferous Limestone. Approx 25% of the catchment is overlain by Boulder Clay, 10% valley gravels, terraces and alluvium. Drift free areas are largely Keuper Marl and sandstone. Diverse land use from moorland to industrial.

The station

Index-Velocity station in the navigable Trent. Main channel approximately 45m wide. Gauged using ADCP boat. Station re-opened in the peak flows dataset in September 2022 (WINFAP Files v11).

How it measures flow

Originally a VA station but prone to error due to variable backwaters. Multipath cross-configuration Ultrasonic Time of Flight station installed 1991. Four major flood relief culverts on right bank and one major culvert on left bank. Velocity Index station since 2008 has been fully calibrated to highest flood flows which includes all bypass flow in a two wage index velocity equation and can be used with confidence across the full flow range from this date onwards. Original TOF gauge (1991 to 2008) did not record out of bank flows accurately as large areas of unmeasured bypass flow. Given the low frequency of such flow during the TOF gauged record an attempt was made to estimate flow at flows above bankfull. Flows are considered accurate based on extrapolation of recent high flow bypass gaugings. Early high flow current meter gaugings appear inaccurate compared to ADCP flood gaugings.

Flow regime

Very substantial flow modifications owing to imports, WRW, cooling water and industrial usage. Reservoir(s) in catchment affect runoff. Regulation from surface water and/or ground water. Runoff reduced by public water supply abstraction and increased by effluent returns. Runoff influenced by groundwater abstraction/recharge.

The flow record

Chart record commences 01/01/1955 with a complete record. Digital record commences 31/12/1982. Station could reliably be used for level only POT from 1955 to 1991, hence POT flow record commences 1991. Full period of record peak flow data reviewed and released in August 2024 (WINFAP Files v13).

Frequently asked questions

Is the River Trent at Shardlow flooding today?

The current level is 0.47m, which is within the typical range of 0.41 to 1.70m. Flooding is unlikely at this level.

Is the river level rising or falling at Shardlow?

Based on the most recent readings, the level is currently steady. The chart above shows the last 12 hours of measurements by default (up to 7 days), updated roughly every 15 minutes.

Why is the level slowly falling?

When little or no rain has fallen for a while, a river level gradually drops as the water stored in the ground and soil drains away with nothing to replace it. This is called baseflow recession and is normal in dry spells. A gentle decline like this is expected and is not a sign of a problem — downstream gauges often recede a little faster than headwaters further upstream, and levels recover once rain returns.

What is a normal level for the River Trent at Shardlow?

The typical range at this station is 0.41m to 1.70m, based on Environment Agency historical data. Levels above 1.70m 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.
