A Gis to Reduce Flood Impact on Road Transportation Systems

Flooding is considered to be one of the most catastrophic forms of natural disaster. The adverse effect of flooding is recognised when it disrupts the road transportation system of a country since it is considered as a country’s socio-economic lifeline. The level of interactions between various measurable flood dimensions and transportation networks determines the potential impact of a flood. By determining interaction probabilities, the flood impact can be modelled, visualised, quantified and evaluated by developing a sophisticated GIS. Besides this, the ways for the reduction of flood impact on the road transportation systems can be demonstrated using the GIS. The paper presents the development of such a system within the framework of an advanced Software Development Life Cycle (SDLC). Finally, the application of the GIS has been demonstrated taking a case study area into account. This enables an understanding of the applicability of the system in analysing, visualising and reducing the addressed problem from various perspectives. In future, the system could be used to assess the flood impact on various objects apart from route networks in an interactive and user-friendly way and therefore can be used as a spatial decision support tool.
