Short summary

The article aims at presenting the first-hand dataset and results from the field investigation, laboratory test, and numerical analysis for the flowslide that occurred on 20 December 2015 in Shenzhen, China: a devastating event causing significant human and property losses. The article concluded that the landfill stagnated groundwater flow and resulted in high water pressure due to the absence of a drainage system, with both disposal rate and amount exceeding the maximum design capacity.
