A Peaty-debris Flow in Glen Docherty, Wester Ross. (2nd January 2017) - Strachan, George J.
ABSTRACT: Glen Docherty has a long history of debris flow activity along the glen's north east slope, but in early August 2015 a peaty-debris flow was triggered on the glen's south west slope, involving an initial slide volume of 190 m 3 debris/peat, of which 89 m 3 consisted of peat. The flow merited study due to (a) its unusual location relative to debris flow activity affecting the rest of the glen, (b) the volume of peat involved and its effect on flow behaviour, (c) the role of immediate post-debris flow fluvial activity and (d) later responses to the event including subsequent weathering, fluvial activity and the potential for debris flow reactivation.
