Description
The objectives of this investigation were: (1) to find the relationship
between the sand movement velocity and the force induced using
a small model basin, (2) to find and build a sand transport meter and
apply the relation from (1) together to measure the velocity fluctuation
and quantity of sand movement on the beach. The idea of model basin
comes from the fluidized bed concept. Using this model, the complicated
influences that happen during the field measurement can be prevented,
and a prime relation can be applied to the field measurement.
In the model basin experiment, the force induced by the drag is
related to the velocity of power around 0. 62. In the field measurement
on the beach, the initial goal could not be reached because of the
appearance of the unexpected low frequency signal which was initiated
by the wave motion itself. However, the device and idea of this experlment
were proven to be good and feasible.
