River Flow

Daily mean discharge (m³/s) with the daily min–max band, from the EA Hydrology API. Flow is the volume of water passing the gauge — often a more direct flood signal than level.

Storm overflows whose water reaches this gauge on the mapped river network, nearest first by distance along the river. The status is each water company's monitor: it says whether an overflow is discharging, not how much or what it contains.
11 storm overflows are traced upstream of this gauge, the nearest 6.6 km away along the river. 0 report discharging now, 11 report not discharging.

🌊 Fairly flashyResponds 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.

Flat-V weir with high flow rating. Ultrasonics used to validate high flow rating. Predominantly clay catchment on the largest tributary of the Medway.
More detail
The catchment
The Beult forms the largest tributary of the River Medway. Weald clay accounts for 78% of the catchment. Base flow is very low for a Kent catchment. Very little natural storage exists causing a flashy runoff regime. Some spring flow is received from Lower Greensand outcrop along northern margin (6% of the catchment) and also from Hastings Beds (consisting of Tunbridge Wells Sands, Wadhurst Clay & Ashdown Sands) which outcrop in the south (16% of the catchment). Predominantly rural with scattered settlements, total urban coverage <1% of total catchment area.
The station
Flat V-weir with high flow rating and single-path ultrasonics installed to help validate high flows. The station is located on a long and reasonably straight reach of the River Beult approx. 110m downstream of the Stile bridge, 12 km upstream of the Medway confluence. Constructed in 2001 to replace existing weir ~30m d/s, a compound broad-crested structure, with the central flume separated by short divide piers (which could trap debris) from the broad-crested flanking sections. The ends of the dividing walls caused disturbance of flow, although modelling showed a negligible overall impact. Regarded as full range aside from largest exceptional events.
How it measures flow
Flat V weir is primary flow calculation. Flood banks confine flows, the floodplain beyond this is approx. 300-400m wide and water now seeps through into adjacent field due to rabbit burrowing. Out-of-bank flows can be significant but are accounted for in the rating. Stepping boards in place on upstream bridge in summer to maintain levels; their insertion and removal is managed separately so the time of adjustment of levels in unknown. But they are far enough upstream to not affect the gauge. Heavy upstream weed growth causes issues with lower ultrasonic paths during summer months. Regular maintenance required but difficult due to depth of channel. Upper ultrasonic paths function well despite this meaning that portion of flow calculated through this method is reliable. The Medway may control the levels in severe floods. Station calibrated by model tests and cableway gaugings (79 cumecs gauged during Oct 2000 flood), though cableway no longer in place.
Flow regime
Small overall impact of artificial influences - all abstraction is agricultural (and therefore very variable). Runoff increased by effluent returns. Some upstream temporary summer weirs and sluices in past. Minor baseflow (from the Lower Greensand) but very responsive regime.
The flow record
Peak flow data pre-2001 are from the weir site. Post-2001 are from weir and ultrasonics. Drop out in daily flows in April 2015 confirmed by the EA, pattern also seen at upstream station. Full period of record peak flow data reviewed and released in September 2019 (WINFAP Files v8).
Timing, not cause. Gauges can move together simply because the same rain fell on both.
Frequently asked questions
Is the River Beult at Stilebridge flooding today?
The current level is 0.12m, which is within the typical range of 0.11 to 3.48m. Flooding is unlikely at this level.
Is the river level rising or falling at Stilebridge?
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.
What is a normal level for the River Beult at Stilebridge?
The typical range at this station is 0.11m to 3.48m, based on Environment Agency historical data. Levels above 3.48m are higher than usually seen and may indicate a flood risk.
How often is this river level data updated?
Readings are supplied by the Environment Agency gauge. FloodRadar checks for updates roughly every 15 minutes; the timestamp above shows how recent the latest available reading is.
