Field Measurements of Undertow on Longshore Bars

Kuriyama, Yoshiaki

Field measurements of undertow over longshore bars were conducted at Hazaki Oceanographical Research Station (HORS) on the Kashima coast of Japan facing the Pacific Ocean. The field measurements, other field measurements and large-scale experiments were compared with one-dimensional models for undertow; one of them was developed in this study. The comparisons showed that the present model well predicted the undertow velocities over longshore bars in the field, while a previous model calibrated with small-scale experiment data underestimated the velocities.
