An important aspect regarding the interventions of hydraulic arrangement conducted with bioengineering techniques is the monitoring of the works over the years and after the occurrence of significant flood events along the waterways. The present paper examines the actions performed on the banks of Chiascio River in the municipalities of Bettona and Torgiano (Perugia Province), near its confluence with the Tiber River, interventions made in the year 2010 and subject to significant floods in the subsequent years, with water flows that have certainly affected the examined structures. The monitoring has focused particularly on a piling located at downstream side of a crossing near an old mill and near of a landslide, rather important, which involved a sector of about 20 meters on the left bank of the Chiascio River. The outcome of this activity allowed a first assessment of such works by highlighting the importance of the construction details and the appropriate choice of materials. The methodical continuation of the monitoring activity, together with adequate remedial measures regarding the damages that were found will allow a more accurate assessment of environmental engineering works over time and their more targeted and effective use.

Abstract
An important aspect regarding the interventions of hydraulic arrangement conducted with bioengineering techniques is the monitoring of the works over the years and after the occurrence of significant flood events along the waterways. The present paper examines the actions performed on the banks of Chiascio River in the municipalities of Bettona and Torgiano (Perugia Province), near its confluence with the Tiber River, interventions made in the year 2010 and subject to significant floods in the subsequent years, with water flows that have certainly affected the examined structures. The monitoring has focused particularly on a piling located at downstream side of a crossing near an old mill and near of a landslide, rather important, which involved a sector of about 20 meters on the left bank of the Chiascio River. The outcome of this activity allowed a first assessment of such works by highlighting the importance of the construction details and the appropriate choice of materials. The methodical continuation of the monitoring activity, together with adequate remedial measures regarding the damages that were found will allow a more accurate assessment of environmental engineering works over time and their more targeted and effective use.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
