Station Description
Complex weir - radial gates and
overfall weirs - embracing two channels. Two u/s and two d/s head recorders.
Calibrated using c/m measurements. All but highest flows contained. Small net
export of water (due to gw abstraction). Closed in 1998.Catchment Description
Mixed geology; runoff from the
Cotswolds (Oolitic L'st) provides a significant baseflow but the Oxford Clay
valley is much more responsive. Land use: rural/agricultural with settlements
concentrated in the valley where gravel extraction is significant.Factors Affecting Runoff
- Runoff influenced
by groundwater abstraction/recharge.
- Runoff increased by effluent returns.
