An introductory, geostatistical and geomorphological review of the effects of geohazards and severe weather events as a retrospect throughout 2009/2010.
Overview
Background & policy context:
There is no form of hazard which has a greater economic impact than natural hazards. While the incidents took place in 2009/2010, there was a need to set together overviews of the disasters distribution and the expected size of events at critical locations.
Certain railway lines shall be studied in this project to understand how the harsh 2009/2010 seasons severe weather and geohazards affected railway transport.
Knowledge of how earlier disasters have been handled is useful in an emergency. During the so called “trainchaos” 2009/2010 it turned out that such information was time consuming and very difficult to obtain. This is the motivation for this project, to gather knowledge, as the basis for handling of future disasters related to geohazards. In case of many of the most devastating events caused by certain climate conditions can the source of the weather be far away from Norway. Also, some of these weather patterns shall be described.
Objectives:
- To understand how climate change affects the frequency, intensity and distribution of extreme weather events.
- To gather today's knowledge of how extreme weather conditions, affect railway infrastructure.
- To quantify vulnerability and socioeconomic importance of railway infrastructure.
- To determine which hedging measures will be most effective in terms of climate adaptation for the railway infrastructure.
Methodology:
The project focuses on natural disasters, the physical impacts - in this case of nature and technology, involving different material and temporal damage. It is usually recommended not to manipulate either the independent nor the dependent variables, so case study method was chosen for this study.
