Detail

This report focuses on headwater streams,-where debrissdams are the characteristic form of large woody debris (LWD) accumulation. The routine removal of LWD from many British rivers for flood defence purposes means that little is found in rivers wider than 10m. For the purposes of this report, a 10m channel width is taken to define the upper width limit for British headwater rivers.
