Sensitivity Analysis of Mike21-BW Diffraction Model by using Breakwater Reflection Coefficient
Author(s):
Abstract:
DHI-Mike Software is one of best softwares describing water wave diffraction in onshore/offshore concepts. Diffraction happens due to obstacles along wave direction and has an important role in designing structures. The scope of this study is to show the relation between Porosity Coefficient and its effects on Diffraction Coefficient (Cd) by means of a suitable and verified numerical model. Porosity Coefficient is one of the breakwaters’ characteristics that describe the reflection quantity of the wave that influences on Diffraction Coefficient. This parameter determines the quantity of obstacles porosity and helps in implementing the sensitivity analysis. A calibrated Model helps as a suitable background to examine different Porosity Coefficients. Reputed "Wave Diffraction Diagrams" has been used for model calibration and will be discussed in detail in an appropriate section. It has been concluded that by increasing the Porosity Coefficient, wave height and Diffraction Coefficient increase.
