Flow Duration Curve for Gauged Daily Flows

Station Description

Multi-path cross-configuration ultrasonic gauging station sited beneath Reading Bridge (incorporates adjustment for flows outside the transducer piers), very minor bypassing via Gosbrook stream. Good c/m confirmation of calibration throughout the range; doppler gauging on 4/1/2003 at 300-310 cumecs. River levels affected by d/s weir and lock.

Catchment Description

Mixed geology with Cotswold headwaters (Oolitic L'st) and Oxford Clay. Land use: predominantly rural but with important, and growing, urban development in the valley (i.e. Oxford and Reading).
