“…During the heydays of its commerce and culture, the connection with the North Sea was assured via a tidal channel, known as the 'Zwin', which -according to some brief historical sources -was formed in the year 1134, following a storm surge or some other catastrophic marine event (De Clercq et al, 2021;Pannier, 1970;Verhulst, 1959). Historical and archaeological research demonstrated that the economic activity was not restricted to the city of Bruges itself, but extended along the Zwin tidal channel via a network of harbours, the so-called outports of Damme, Monnikerede, Hoeke, Mude and Sluis which were thriving towns on their own (Figure 1) (De Clercq et al, 2017Leloup, 2018;Trachet et al, 2016Trachet et al, , 2017aTrachet et al, , 2017bTrachet et al, , 2017cTrachet and De Clercq, 2018). In the course of the Late Middle Ages, the Zwin steadily lost its function as an economical viable transport route.…”
