PhDTalks | Sediment transport monitoring and Smart-Sed, a new sediment erosion and transport model

Luglio 18 @ 17:15 - 18:30

Il prossimo appuntamento con la serie di incontri PhDTalks si terrà Martedì 18 Luglio nell’aula 2.1.3 (Edificio 2), dalle 17:15 alle 18:30 CET.

PhDTalks è una serie di seminari e discussioni tra dottorandi. Gli eventi hanno lo scopo di fornire un luogo dove creare un network tra dottorandi ed entrare in contatto con i molti progetti sviluppati nel nostro dipartimento.

La speaker Monica Corti condurrà un seminario dal titolo “Sediment transport monitoring and Smart-Sed, a new sediment erosion and transport model. 

Al termine dell’evento sarà disponibile un piccolo rinfresco finanziato dal dipartimento.

Sarà possibile seguire la conferenza anche online al seguente link.


The development of smart strategies for geo-hazard management in urban areas has lately become crucial in relation to the higher occurrence of extreme events, expected as a consequence of climate change. Therefore, the engineering geology research group of Politecnico di Milano has recently developed a new sediment erosion and transport model, called SMART-SED.
The advantages of SMART-SED with respect to other similar models are the automatic detection of the drainage zones, the statistical downscaling of soil granulometry input maps and the evaluation of the factor of safety at catchment scale. Moreover, the input data required are few and they are usually open data.
After studies on sediment transport on a mountain catchment located near the Lecco campus of Politecnico, the model was successfully calibrated and validated, given the availability of field data over time. Then, different applications were successfully tested, as the dam filling evaluation in catchments characterized by different bedrocks in the Italian Alps and in the Apennines. In addition, the back-analysis of some well-known Italian floods and debris flows events was accomplished, considering as input the relative rainfall data, and a simulation of a climate change scenario from the General Circulation Model was performed to understand possible future hazard scenarios.
A general good performance of the model was observed also for the identification of the unstable slopes and of the flooded areas, based on comparison with the Italian landslides inventory and with Sentinel Hub maps. Finally, the simulation of the climate change scenario show an increase of the magnitude of solid and water discharge that has to be taken into account for the adaptation of the actual rainfall thresholds to the future rainfall regimes.
The proof of the reliability of SMART-SED results is considered important for the development of a complete hydrological model that can represent an innovative tool for urban planning and risk mitigation in a climate change scenario.

Speaker’s bio:

Monica graduated in Geological Sciences and Technologies at University of Milano-Bicocca in 2019. She has collaborated with Politecnico di Milano working on topics related to engineering geology since 2019, and she is currently enrolled in Environmental and Infrastructure Engineering PhD program (37° cycle) at the Department of Civil and Environmental Engineering of Politecnico di Milano. Her research deals with shallow processes related to sediment erosion and transport.

In her free time, Monica enjoys hiking and travelling.
