Abstract

This study investigates the shoreline dynamics of the Can Tho River during the period 2010–2025, focusing on both the southern and northern riverbanks. Shoreline data were analyzed using the linear regression rate (LRR) to estimate the annual rate of change, combined with charts and maps to illustrate the spatial and temporal patterns of erosion and accretion. Results indicate that the northern bank is dominated by accretion, accounting for 51% of its length, with 5% experiencing erosion and 44% remaining stable. In contrast, the southern bank shows 34% accretion, 9% erosion, and 57% stability. Erosion hotspots are mainly located at narrow and meandering sections, which are strongly influenced by river flow and ship waves, while accretion areas appear along straight or wider sections of the river. The findings provide essential scientific insights for riverbank management and planning in the Can Tho River, highlighting the critical zones that require prioritized protection and continuous monitoring.
