Given the circumstances, an eight-member tech team consisted of doctors and led by Professor Deng Juzhi came to the frontline and tried to locate hidden danger spots by scanning the dike with ground penetrating radar and an independently developed 3D resistivity imaging system, to support local flood control efforts.

Dr. Zhou Cong (R) and Dr. Wu Chaofeng lay the wires for the 3D resistivity imaging system on the inner dike of the Furong River in Furongdun Town of Jiujiang City, east China's Jiangxi Province, July 21, 2020.
