Systematic methodology for planning and evaluation of a multi-source Geohazard monitoring system. Application of a reusable template

Abstract

In this paper geohazards and their monitoring are considered in the general context of reservoirs and dams. A systematic methodology is used to identify and characterise multiple causes and effects, as well as their interdependencies. This methodology originated at NASA as a part of the safety management of the space program. Here, a recently presented, multi-system expansion of the method is introduced, which has been used to capture complicated data into a reusable template represented by interrelation matrices. This template has a general relevance for monitoring geohazards considering the safety of reservoirs and dams. The methodology and the related system analysis possesses some powerful diagnoses possibilities. The template is for instance, used to reveal the potential safety value of a multi-source system installed for monitoring geohazards in conjunction with a large reservoir in Iceland. The method presents an important step in a holistic risk and safety management of reservoirs.
