All rights reserved.A storm tide event (the sum of the astronomical tide and the storm surge) along the southern coast of Java has been simulated by using a two-dimensional (2D) ocean model (barotropic version of Mike 21). In this study, we simulated the storm surge generated by the Cyclone Jacob during 2−12 March 2007 and Cyclone George during 3−9 March 2007 in northwestern coastal waters of Australia. The applied model based on an unstructured grid approach employs finite volume method to solve the governing equations. The applied model allows for a highly flexible discretization of the model domain. This is demonstrated by grid sizes, which vary from ˜50km in the deep ocean to a considerably higher resolution of about 150m in the coastal area. To simulate water run-up and inundation processes, flooding and drying (FAD) capabilities of the model were enabled. The model domain covers the northeastern part of the Indian Ocean and the coastal areas of the southern part of Java. The storm tide event was simulated by imposing tidal elevations at the open boundaries, 6-hourly wind and air pressure data. Tidal elevation data was derived from the tide model driver (TMD), while wind and air pressure data were obtained from NCEP (National Centers for Environmental Prediction). The weekly TOPEX Poseidon Sea Level Anomaly (SLA) was used to validate the model results of surge height. The simulation results show that the storm tides had attacked and inundated coastal areas of the southern part of Java. Nusa Kambangan (a part of Cilacap Regency) experienced the highest surge among the other stations, about 0.19m, at 17:00 UTC on 7 March 2007. Maximum distance of storm tide flooding occurred at Telereng Cape (about 500.4m), Penanjung Bay (about 835.2m), and Pelindu Cape (about 710.6m) in which each of those areas representing the western, central, and eastern part of the the southern coast of Java, respectively. Meanwhile, water run-up heights at the locations where the maximum distance of flooding occurred, are about 0.51m (at the Telereng Cape), 0.73m (at the Penanjung Bay), and about 0.93m (at the Pelindu Cape).[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1142/9789814355353_0006[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
