We have studied the morphology and the morphometric relations between alluvial fans and drainage basins in a bajada system including more than 20 coalescent fans developed since the Late Pleistocene as a result of the recent uplift of the Sierra Nevada (Betic Cordillera, Spain). Three allocycles of tectonic origin were recognised across which there is a clear evolution from debris flow to sheet...

Urban gullies are a rapidly growing concern in many tropical cities of the Global South. Various measures already implemented for their stabilization. However, an overview these and overall effectiveness is currently lacking. We aim at addressing this gap by documenting existing initiatives to stabilize urban D.R. Congo assessing effectiveness. To end we conducted extensive field campaigns Kins...

Our long-term scientific goal is to develop sound theoretical models for submarine sediment movement that can be used to predict the initiation, spatial development, and time duration of mud flows and turbidity currents. Of great interest are the characteristics of the sedimentary deposits that these flows generate, in particular their capability to develop bed forms and gullies by means of sed...

Gullies contribute very efficiently to soil loss and degradation, particularly in Mediterranean environments. While natural factors are involved gully formation further development, anthropic action is almost always an element. Knowledge of development important if protection strategies measures be effective. In this paper, we identify the most gullies a setting based on study Alva (central Por...
