Dynamics of Sand Ripples Generated by Irregular Waves

When we want to reproduce transport of sediment in the fields in a laboratory, we have to establish a similitude law. A similitude law is necessary when sediment transport of field is reproduced in a laboratory. When we apply our knowledge about sediment transport obtained in the laboratory to predict sediment transport in the field, we can apply Froudian law to a fluid motion that becomes agitation agency and transporting flow of sediment movement.
