Abstract

The reproduction of meteorological tsunamis utilizing physically based hydrodynamic models is complicated in light of the fact that it requires large amounts of information, for example, for modelling the limits of hydrological and water driven time arrangement, stream geometry, and balanced coefficients. Accordingly, an artificial neural network (ANN) strategy utilizing a backpropagation neural network (BPNN) and a radial basis function neural network (RBFNN) is perceived as a viable option for modelling and forecasting the maximum peak and variation with time of meteorological tsunamis in the Mekong estuary in Vietnam. The parameters, including both the nearby climatic weights and the wind field factors, for finding the most extreme meteorological waves, are first examined, through the preparation of evolved neural systems. The time series of meteorological tsunamis were used for training and testing the models, and data for three cyclones were used for model prediction. Given the 22 selected meteorological tidal waves, the exact constants for the Mekong estuary, acquired through relapse investigation, are A = 9.5 × 10−3 and B = 31 × 10−3. Results showed that both the Multilayer Perceptron Network (MLP) and evolved radial basis function (ERBF) methods are capable of predicting the time variation of meteorological tsunamis, and the best topologies of the MLP and ERBF are I3H8O1 and I3H10O1, respectively. The proposed advanced ANN time series model is anything but difficult to use, utilizing display and prediction tools for simulating the time variation of meteorological tsunamis.

Highlights

  • In the last decade, many hybrid artificial intelligence learning techniques have been adapted for environmental issues [1, 2]

  • A meteorological tsunami is a meteorological tide caused by an unusual increase in the level of ocean water, initiated by the low atmospheric pressures related to a hurricane or typhoon, such as those which regularly strike Vietnam [3]. e height of a meteorological tidal wave at a specific area is obtained by subtracting the anticipated galactic tide from the real recorded ocean level [4]. e danger of flooding in low-lying beach front regions is heightened by the occurrence of higher spring tides alongside genuine meteorological tidal waves

  • Ζ(t + 1) f[ΔP(t + 1), U(t + 1), ζ(t)] is used as an input variable for the evolved neural networks (ENN) models, which shows that the time series of the meteorological tsunami can be consecutively predicted. is study uses a multilayer, multioutput feedforward artificial neural network (ANN) model, which is trained using the precomputed storm surge and onshore flooding datasets

Summary

Introduction

Many hybrid artificial intelligence learning techniques have been adapted for environmental issues [1, 2]. E least difficult technique for predicting the most extreme meteorological tidal wave is to utilize the exact equations [4, 5]. E models have only been used to predict the rise in ocean levels during storms, rather than meteorological tidal waves [12].
