Description :
This study focuses on reaches that are the most critical from a large woody debris (LWD) management perspective. An example management application is provided whereby the calculated LWD recruitment for each reach is used to predict the potential significance of the LWD recruitment in terms of debris dam formation. From this basis, rational management decisions may be taken. The overall accuracy of the model is largely dependent on 3 factors, namely : bank-stability analysis, knickpoint dimensions and migration rate, and characterisation of the riparian tree stand.
