The purpose of this paper is to study floods, groundwater pollution and landslides in a small watershed characterized by high hydrogeological hazard, high population density and widespread industrial and commercial settlements. Measurements were performed to study hydrogeological hazard in the watershed during 2011, 2012 and 2013. First the relation between groundwater and surface water was estimated; second, the rainfall-runoff relationship was assessed. Some rainfall events were analysed to investigate the watershed behaviour in different periods over the hydrologic year. The analysis stressed the importance of the rainfall events, soil moisture and hydrological conditions. From this study it’s apparent that the natural hazard (i.e. floods, landslides and pollution hazard) can be better individuated and predicted in a small basin rather than in a wider one. Furthermore, these studies can be easily implemented in other basins with similar features in all the northern Mediterranean area.

Abstract
The purpose of this paper is to study floods, groundwater pollution and landslides in a small watershed characterized by high hydrogeological hazard, high population density and widespread industrial and commercial settlements. Measurements were performed to study hydrogeological hazard in the watershed during 2011, 2012 and 2013. First the relation between groundwater and surface water was estimated; second, the rainfall-runoff relationship was assessed. Some rainfall events were analysed to investigate the watershed behaviour in different periods over the hydrologic year. The analysis stressed the importance of the rainfall events, soil moisture and hydrological conditions. From this study it’s apparent that the natural hazard (i.e. floods, landslides and pollution hazard) can be better individuated and predicted in a small basin rather than in a wider one. Furthermore, these studies can be easily implemented in other basins with similar features in all the northern Mediterranean area.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
