Catchment Character

🌊 Groundwater-fed Slow and steady — fed largely by groundwater, so levels change gradually, not in sudden spikes.

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

Electromagnetic gauging station with insulated bed.

More detail

The catchment

A predominantly Chalk catchment with significant patches of superficial deposits. Largely rural with some woodland and scattered settlements.

The station

Installed 1983 - calibration confirmed by current-meter. Superseded a velocity-area station heavily affected by weed growth; weekly weed cutting can be necessary. Slight narrowing of channel upstream of section to flush out gravel and maintain a clear section. This has caused a small riffle in the centre of the section.

How it measures flow

Ultrasonics employed as backup and for high flows at same site; performs well at high flows. Limited stage and velocity range makes for effective operation. As the hut is near the bridge and not near the gauging station there are problems with signal degradation during transfer between the two locations.

Flow regime

Largely natural baseflow-dominated regime (some abstraction for cress beds) but groundwater augmentation during severe droughts.

Frequently asked questions

Is the River Itchen at Easton flooding today?

The current level is 0.68m, which is within the typical range of 0.51 to 1.10m. Flooding is unlikely at this level.

Is the river level rising or falling at Easton?

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 Itchen at Easton?

The typical range at this station is 0.51m 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.
