J. of GEOMATE.Dam break flood flow might lead to a very high risk of a disaster causing massive destructions either in life or property. It is more complicated if it occurs in an urban area due to the appearance of buildings that block the flow. Modeling is a tool that is common use to study dam break flood propagation to provide information of flow characteristics and mechanism of a dam break. Experimental model has been preferable due to difficulties in obtaining field data during flood flow. In this study, an experimental model with several configurations of blockages to simulate dam break flow in the urban area is developed. The purpose is to investigate flow properties in term of flow depth and flow velocity due to dam break flood flow in the urban area in term of mitigation plan and to provide a valuable tool for numerical model calibration and validation for the numerical model. The model is developed for no building case and several configurations of blockages. Flow depth and flow velocity at several points are observed to investigate flow properties. Based on the results, it is found that a significant change in water depth occurs in t = 5 seconds until t = 7 seconds. Flow velocity is also found to increase uniformly at all observed area. It is also found that energy in one building configuration is much bigger than in no building case. Furthermore, flow occurred in the no building model is subcritical and supercritical flow while in one building configuration, the flow is subcritical flow.[/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]Blockages configuration,Dam break,Disaster mitigation,Experimental model,Flood flow[/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/10.21660/2019.58.97684[/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]
