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).Factors
Affecting Runoff
- Runoff reduced by public water supply
abstraction.
- Runoff influenced by groundwater abstraction/recharge.
