APPLICATION OF ADOPTIVE NEUERO FUZZY INTERFACE SYSTEM (ANFIS) IN PREDICTING REFLECTION COEFFICIENT OF A PERFORATED QUARTER CIRCLE BREAKWATER

Abstract

Breakwaters are constructed for creating tranquil zone on the lee side to minimize the motion on ships due to the wave for easy handling of goods, apart from shoreline protection work etc. Due to the increase in demand for the coastal development all over the world, number of innovative Breakwaters was evolved as against the rubble mound. Recently, in order to further economize these innovative structures, Quarter Circular Breakwater (QCB) has been evolved. The coastal structure is subjected to hydrodynamic forces, involving various parameters while designing a safe and economical structure. The laboratory experiments are conducted in the wave flume in the National Institute of Technology, Surathkal Karnataka, India. In the present paper reflection coefficient (Kr) of a perforated QCB with S/D-3 (spacing to perforation diameter ratio) is predicted applying Adoptive Neuro Fuzzy Interface System (ANFIS) in MATLAB. The predicted values of reflection coefficient are compared with the experimental values.
