Catchment Character

🌊 Fairly flashy Responds fairly quickly to rain, with moderate baseflow between events.

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

A gauging station located in the lower River Quin catchment that is located within the River Lee system.

More detail

The catchment

A mainly impervious catchment with extensive glacial deposits overlying Chalk. Agricultural land use predominates but there is some urban development close to the gauging station.

The station

Flat V weir, 4.5m wide. Shallow depth of approach.

How it measures flow

Calibration assumes station is not subject to drowning.

Flow regime

Net export of water has increasing from the mid-1980s. Gw abstractions can be especially significant during droughts e.g. late-1990. Stable baseflow but responsive to storm events; sewage effluent discharge pattern also sometimes detectable.

What is a normal level for the River Quin at Braughing?

The typical range at this station is 0.06m to 1.10m, based on Environment Agency historical data. Levels above 1.10m 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.
