Numerical modeling of wave overtopping distribution over non reshaping berm breakwater Mahmood Nematollahi Mahmood nematollahi@cv iut ac ir 13 Jan 2018 Department of Civil Engineering Isfahan University of Technolgy Isfahan 84156 83111 IranDegree M Sc Language FarsiSupervisor Dr Mohammad Navid Moghim moghim@cc iut ac ir AbstractWave overtopping phenomenon and its spatial distribution over breakwaters is so crucialmatter in coastal engineering because of structure s security and people s safety The amountof water that run up and cross over the crest of breakwater determines the rate of waveovertopping One of the most practical breakwaters is berm breakwater Nowadays because ofhigh cost and timing of experimental models numerical models have been propagated Numerical simulation of fluid flow in permeable breakwater with non reshaping berm has beendone with Flow 3D software After understanding the theory of fluid dynamics and someturbulent models geometry of the breakwater structure had designed in Auto CAD Domainof parameters and boundary conditions are specified in software and after modifying meshreticulation the model has calibrated by porosity of layers Therefore the numerical model ofberm breakwater has verified by 3 different irregular waves In 3rd part of this study numerical models have applied with different amount of parametersand results have been collected Dimensionless parameters have extracted by dimensionalanalysis that based on Pi Buckingham method After combination of these parameters efficacyof each parameters have been studied by using diagrams At last a new formula had proposedin this thesis to calculate spatial distribution of wave overtopping over breakwaters with non reshaping berm The various factors of wave overtopping distribution like berm width armorfreeboard wave height and water depth above berm have been studied Also experimentalstudies have carried out to investigate the performance of the model The computations of thewave overtopping under irregular waves have compared with the experimental data indicate avery good agreement Comparisons of suggested formula with experimental data and empiricalformulae show a very good performance of this model The present model is expected tobecome an excellent tool for overtopping prediction in the near future Keywords Non Reshaping berm breakwater Wave overtopping Irregullar wave Numerical Model suggested formula
