Analysis of geomorphic systems' response to natural and human drivers in northern Spain: Implications for global geomorphic change

► 20th century sedimentation rates in N Spain show in general increasing trends. ► Increasing rates do not seem to be related to rainfall trends. ► Indicators of human activity provide a better match with sedimentation rate trends. ► Results are coherent with an acceleration of processes (global geomorphic change). ► Increasing geomorphic hazards appear to be a consequence of that change.
