The aim of this paper is to find an effective model between MIKE 21 - numerical model and an Artificial Neural Network (ANN) model in predicting sea level height in Qui Nhon, Vietnam during four storm events: Ketsana-2009, SonTinh2012, Nari-2013 and Wutip – 2013. | Comparative evaluation of artificial neural network and MIKE 21 in estimating storm surge level
