The comprehension of wave run-up is essential to coastal engineering.
It is required to obtain an understanding of beach profile changes, beach recovery
and the interaction of waves on coastal structures. Several empirical expressions
have been defined to predict extreme wave run-up positions through the
comparisons of offshore wave parameters, beach slopes and synchronous run-up
observations. This paper assesses the accuracy of wave run-up formulae on three
Trinidad beaches. Run-up data were collected using Traditional Surveying
Techniques and statistically analysed to determine both the maximum run-up and
the 2% run-up exceedance. Observed values of wave run-up were compared to
values predicted by four (4) field wave run-up models. All models were found to
inadequately predict run-up observations with an occurrence of predominantly
overestimations. Stockdon et al.  provided the best estimation of run-observation
with root mean square error and scatter index of 0.15.
