Project description:

In the context of coastal engineering study, was a) numerical simulation of waves’ transformation from deep water to the study area and b) numerical modelling of sediment transport under wave’s  action.

  • Numerical modeling: simulation of wave’s transformation with CGWAVE software package which solves the equation for mild slope equation mild, and is based on the method of Xu, Demirbilek and Panchang (1996), taking into account the refraction, diffraction and reflection of sea waves. Calculated a) the wave propagation in the coastal zone and b) wave’s agitation in the small harbour basin. Studied alternative harbor works so that on the one hand not caused adverse impacts on adjacent coasts and the wave height in the new quay walls shall not exceed 0,30 m.
  • Sediment transport : with method CERC, calculated the tendency of sediment’s motion taking into account the wave characteristics, as extracted from the available components according. The waves’ time series established by statistical data 11 years according. Based on the results of the calculations, estimated the expected profile of the neighboring Beach in the area of direct influence of the fishing’ shelter after construction of harbor works.
