  abstract = {{T}he present study focuses on the long-term multi-year evolution of the shoreline position of the {N}ha {T}rang sandy beach. {T}o this end an empirical model which is a combination of longshore and cross-shore models, is used. {T}he {N}ha {T}rang beach morphology is driven by a tropical wave climate dominated by seasonal variations and winter monsoon intra-seasonal pulses. {T}he combined model accounts for seasonal shoreline evolution, which is primarily attributed to cross-shore dynamics but fails to represent accretion that occurs during the height of summer under low energy conditions. {T}he reason is in the single equilibrium {D}ean number {O}mega(eq) of the {S}hore{F}or model, one of the components of the combined model. {T}his equilibrium {D}ean number cannot simultaneously account for the evolution of strong intra-seasonal events (i.e., winter monsoon pulses) and the annual recovery mechanisms associated with swash transport. {B}y assigning a constant value to {O}mega(eq), when the surf similarity parameter is higher than 3.3 (occurrence of small surging breakers in summer), we strongly improve the shoreline position prediction. {T}his clearly points to the relevance of a multi-scale approach, although our modified {O}mega(eq) retains the advantage of simplicity.},
