ABSTRACT
Chapter 6 describes the influence of ground water on slope stability, and how ground water pressures are related to hydraulic conductivity. The method of constructing flow nets, composed of flow lines and equipotentials, to find the pressure distribution within a slope are demonstrated. The influence of geologic structure on hydraulic conductivity is discussed, and typical flow nets in anisotropic rock are presented. Water pressure measurements using piezometers of different types, such as standpipe and vibrating wire sensors, are reviewed, as well as packer tests and pump tests to measure hydraulic conductivity.
