This paper discussed the methods typically used to monitor the pore pressure regime in tailings dams, concluding with a recommended approach to monitoring and the subsequent stability analysis. Monitoring of the seepage regime in a tailings dam during its operational life forms an essential part of the continuing surveillance as the dam gains height. In the tailings dam industry it is common practice to use standpipe piezometers to monitor the pore water regime. A number of single standpipe piezometers along a section across the dam wall are generally used. The water level in the standpipe is assumed to represent the phreatic surface and it is then assumed that pore pressures increase hydrostatically with depth. This seepage regime is then used in the stability analysis of the tailings dam walls.
