•An enhanced particle shifting technique (PST) is presented to overcome the deficiencies of traditional PSTs.•The volume-non-conservation issue is tackled by introducing a corrective cohesion force between particles.•The non-physical gap issue is alleviated by introducing a different free-surface tr...
