This area is located in a vulnerable area of land movement. The aim of this research is to reconstruct subsurface models which will be related to the distribution of fracture zones and landslides. The data acquisition is performed using a 3D GPR approach. The Lodan Dam area is divided into three segments, the upstream segment, the top of the dam segment, and the downstream segment. The profile results of the three segments use the amplitude response of the rocks. The response to amplitude values indicates the presence of a water-saturated zone. In addition, the GPR data profile of the subsurface model parameters is represented by a pseudo-3D representation. So that can be seen zone saturated water in each profile identify the existence of fracture zones or landslides in the subsurface. The water saturation zone affects the soil load from the crags on the hill. Thus, this existence triggers a crack in the drainage concrete.[/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]a pseudo-3D representation,Amplitude response,Fracture zone,reconstruct,Saturated water,Subsurface model,Vulnerable area,Water saturations[/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]a pseudo-3D representation,fracture zones,landslides,reconstruct,water saturation zone[/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/10.1109/ICGPR.2018.8441562[/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]
