Abstract

Slope movement monitoring enables rates of ground movement to be measured and assessed, allowing:

  • confirmation as to which slopes are undergoing movement during the early stages of a road construction project;

  • confirmation of the areal extent and depth of movement (if inclinometers and slip indicators are used; see Section B5.4);

  • a decision to be made as to when investment in stabilization measures is required;

  • the performance of implemented stabilization measures to be assessed and whether any further works are required; and

  • the development of a monitoring database that relates recorded ground movement to rainfall patterns in order to be able to assess future risks.

Desk studies and field obxservations (Sections B2 & B3) will help define the more obvious landslide areas, but it is possible that other failed slopes may not be so readily identifiable and may be subject to slow or periodic ground movements. Slope monitoring can be used to help confirm whether movement is occurring in these areas. The sooner slope monitoring schemes are put in place, the greater the length of time available to collect a reliable dataset (e.g. discussion in Baynes et al. 2010).
