Land Use / Management Changes

All grips in the Brennand catchment have been blocked; total length 28.3 km. Fences have been placed along the river banks and on the moors. Low stocking levels for habitat regeneration are being maintained in the headwaters. Stock is excluded on the western slope of the Brennand River, and in the riparian zones where trees have been planted. Mixed broadleaf trees have been planted in riparian zones throughout the catchment and on some hill slopes near Fox Clough and Tarn Clough on the western slopes of the Brennand River.

Channel Description

The channel cross-section at the instrument location 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.)
