LITTORAL DRIFT MODEL FOR NATURAL ENVIRONMENTS

Rolf Deigaard, Jorgen Fredsoe, Ida Broker Hedegaard, Julio A. Zyserman, Ole Holst Andersen

Abstract


The littoral drift model developed at DHI and ISVA, see Deigaard et al. (1986b) has been extended to include the effects of the irregularity of the waves, of a coastal current and a wind acting on the surf zone. Further, a mathematical model to simulate the near-shore current pattern along a barred coast with rip channels has been developed. The influence on the littoral drift of the irregularity of waves, wind, coastal current, and rip channels is discussed. It is concluded that irregularity of waves and presence of rip channels must be considered while coastal current and wind action are of minor importance.
