Landslide early warning systems, which are installed at prone areas, measure physical parameters closely related to landslides and give warning signals indicating that landslides would occur. To determine the critical values of the measured physical parameters or test the early warning system itself, a laboratory scale model of a rotational landslide was developed. This rotational landslide model had a size of 250×45×40 cm3 and was equipped with soil moisture sensors, accelerometers, and automated measurement system. The soil moisture sensors were used to determine the water content in soil sample. The accelerometers were employed to detect movements in x-, y-, and z-direction. Therefore, the flow and rotational landslides were expected to be modeled and characterized. The developed landslide model could be used to evaluate the effects of slope, soil type, and water seepage on the incidence of landslides. The present experiment showed that the model can show the occurrence of landslides. The presence of water seepage made the slope crack. As the time went by, the crack became bigger. After evaluating the obtained characteristics, the occurred landslide was the flow type. This landslide occurred when the soil sample was in a saturated condition with water. The soil movements in x-, y-, and z-direction were also observed. Further experiments should be performed to realize the rotational landslide.[/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]This work was financially supported by the University’s Excellence Research (PUPT) Grant in the fiscal year of 2016.[/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/10.1063/1.4987085[/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]
