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.

The physical character of the land that drains to this gauge, and how it shapes its flood response — from the National River Flow Archive (UKCEH).

About this gauge

Cross-correlation gauge on the Meden to measure flows downstream of the Sherwood Sandstone.

More detail

The catchment

Moderate to low relief catchment underlain by the Notts coalfield. The Maun rises on generally sandy facies of the Magnesian Lst, crosses onto Sherwood Sst, the gauge sited close to the junction with the Mercia Mudst. Upper catchment dominated by urban centres (Mansfield) and mining spoil; middle and lower reaches rural and forest.

The station

Replacing d/s station (28045). Data from cross-correlation gauge commences in 2019. Prior measurement from Flat V weir with 1:10 cross slopes, Crump profile, 5.2m wide, wing walls at 0.64m.

Flow regime

Subdued response with WRW effluent augmenting low flows.

The flow record

No daily flow data available July 2013 - September 2016 due to subsidence of the weir. Flows from October 2016 onwards are calculated through a new rating and from February 2019 onwards from the cross-correlation gauge. June 2007 high flows were over the wingwalls of the structure.
