title = "Undertow Currents in a Prototype Beach",
abstract = "The objective of this field study is to obtain a relationship between the measured near bed undertow current speed and the beach slope which will be compared with the mean flow velocity derived using linear wave theory by Dally (1980). The mass of water carried shoreward by the breaking waves in a surf zone will, in a two-dimensional situation, be compensated by a seaward return flow, the undertow. The undertow currents best develop in a two dimensional situation like in a laboratory wave-flume. To represent such a situation in the field two headland bays and a straight beach where waves approach almost normal to the shoreline were selected for the current measurement. The six sets of field data were used to compute time averaged normalized near bed undertow current speed. It was found that the data matches reasonably well with the theoretical relationship.",
