Short summary
Large woody debris (LWD) is a natural element of mountain streams that has many positive ecological effects. In the present study, we investigate different techniques of incorporating stable in-channel LWD in a hydrodynamic model to simulate its impact on flood hydrographs in a small high-gradient creek. The results indicate the applicability of different integration methods with respect to the simulation scale.
