Using georadar as a dam pore water pressure measurement — case study of Sutami Dam

The piezometer is used to measure pore water pressure in the dam's core and placed in the upstream and downstream where if the upstream is higher than the downstream, the dam is in good condition. The piezometer measures pore water pressure based on the water levels above itself. This water lev...
