Abstract: In July 2021, an intense precipitation event has hit Belgium severely. While most of the damages occurred in the Eastern part of Belgium along the Vesdre valley, other catchments also endured severe floods. This is the case for the municipality of Aiseau-Presles located in the Biesme catchment, a tributary of the Sambre River, illustrated in Fig. 1. As can be seen in Fig. 1, the subcatchment relative to the study site (51 840 m2) presents a local steep slope and a series of houses are located close to the Biesme River. During the July 2021 event, water depths up to 2 m were observed around the houses located along the Rue Lambot. The question raised by the municipality concerned the causes of these inundations: were these mainly due to excessive runoff along the steep slopes or to overflowing of the Biesme river?
