Instrument: Brennand grip / Brennand grip weir
|ID>||BRE_grip / BRE_grip_weir|
|Location #||20.1 / 20.2|
|Measurement||Stage measured at two sites, located in the grip (BRE_grip) & at a weir (BRE_grip_weir)|
|Catchment||Sapling Clough, a headwater tributary of the Brennand|
|OS Grid ref||SD 62692 55949|
|Data availability||BRE_grip: 15/05/08 - 06/09/09 & BRE_grip_weir: 26/11/08 - 31/01/10 (weir leakage 26/11/08 - 01/12/08 & 06/06/09 - 25/06/09)|
|Location||A grip feature that was blocked upstream of the gauge location in in Nov 2008.|
|Abstractions||No upstream United Utilities abstraction points|
|Related sites||Upstream site: none; downstream site BRE_sap; other sites in Brennand subcatchment, BRE_rhw and BRE_out|
Data DownloadCross section survey data, stage/discharge data (including manual measurements of stage) and time series of levels (not corrected for atmospheric pressure) may be downloaded here (1.7mb). (For details on using the data click here.)
Land Use / Management ChangesThe main land use management change is the blocking of the grip, but stocking density has also been reduced on the moor.

Channel DescriptionThe channel cross-section at the BRE_grip is provided below. Datum is taken as the top of the diver access tube (red bar). Width is measured from the left-hand side bank when looking downstream, with locations to left of the diver tube taken as negative and those to the right positive. Details from an MSc student project are available here. (Note, the information above takes precedence over the student report.)
Stage-Discharge MeasurementsA theoretical stage-discharge relationship exists for BRE_grip_weir (a V-notch thin plate weir conforming to BS3680). Rating points for BRE_grip are provided below.
