Flow Duration Curve for Gauged Daily Flows

Station Description

Flat V weir installed in Oct 1988 in an artificial meander cutoff. Previously velocity-area station: instability in rating caused by d/s deposition. Straight, uniform channel (concrete walls) lined with gabions; banks are steep to 2.5m. Ratings extrapolated above 1.6m, but not taking bridge into account. Catchment contains Carron Valley Reservoir. Export of water and operation of reservoir can significantly influence flow patterns.

Catchment Description

The upper part of the catchment drains part of the Campsie Fells. Bedrock composed of igneous rocks in headwaters and Carboniferous rocks in the valley; approx. 70% of which his overlain by superficial deposits. Land use predominantly moorland and plantation forestry in headwaters, pasture in lower reaches.

Factors Affecting Runoff

Reservoir(s) in catchment affect runoff.
Runoff increased by effluent returns.
