  abstract = {{A} field experiment was conducted at a tropical microtidal intermediate sandy beach with a low tide terrace ({N}ha {T}rang, {V}ietnam) to investigate the short-term swash-zone hydrodynamics and morphodynamics under variable wave conditions. {C}ontinuous 2{D} {L}idar scanner observations of wave height at the lower foreshore, subsequent run-up and swash-induced topographic changes were obtained. {T}hese data were complemented by detailed real-time kinematic {GPS} topographic surveys. {V}ariable wave and tide conditions were experienced during the field experiment with relatively large swell waves (offshore significant wave height, {H}-s = 0.9 m to 1.3 m; peak wave period, {T}-p = 8 to 12 s) concomitant with spring tides at the beginning of the period, followed by mild wind waves (offshore {H}-s under 0.5 m and {T}-p 5 s) and neap tides. {T}his resulted in the following morphological sequence: berm erosion followed by rapid neap berm reformation and beach recovery within a few days. {N}ew insights into the link between intra-tidal swash dynamics and daily beach profile evolution were found using the {L}idar dataset. {W}hile waves directly cause morphology changes on a wave-by-wave basis, tidal levels were found to be a key factor in determining the morphological wave-effect (accretive or erosive) due to modulated interaction between surf and swash hydro-morphodynamics.},
