This paper reviews hydro-geomorphic response models for burned areas and explores how modelling approaches and sources of uncertainty change depending on the focus question (or purpose) and the associated spatial-temporal scale of the model domain

Energy gradient and geomorphological processes along a river influenced by neotectonics (the Saône river, France)
Le but de cet article est de mettre en relation le transit et le stockage des sédiments d'un cours d'eau, la Saône, et les caractères hydro-morphologiques de l'hydrosystème, approche encore peu appliquée à la dynamique des sédiments. Une

This paper presents a review of research on macrophyte-mediated processes within streams and calls for a greater appreciation of these processes in future hydro-geomorphological research in streams with abundant vegetation. The influence
Principles of engineering geomorphology for managing channel erosion and bedload transport, example from French rivers

French rivers have been transformed by centuries of development to satisfy various social demands such as navigation, hydro-electric power production, flood control, or checking erosion. These modifications have led to impacts that are detrimental
long-term management strategies is of the highest importance. The principles of engineering geomorphology are developed here.

Geomorphology in the public eye : policy issues, education, and the public. Special issue
hydrology and geomorphology play an important role in understanding the dynamics of the present bird population and in designing a recovery plan. The installation and operation of dams are the most important causes of hydro-geomorphic and ecological change
