Question

methodology of project on flood 2019​

Answer 1

Nowadays, flood risk management is gaining importance in order to mitigate and prevent flood disasters, and consequently the analysis of flood risk components is becoming a key research topic. In this paper, we propose a methodology for large-scale analysis of flood susceptibility and vulnerability. The methodology is based on a GIS-based index, which considers local topography and basic information about the flood scenario to reproduce flooding processes. Its application allows for considering different levels of complexity of flood scenarios, from localized flood defence failures to complex hazard scenarios involving river reaches. The methodology synthetizes the spatial distribution of the index values into maps and curves that can be used to rank the susceptibility and implement a vulnerability analysis in the area of interest. The components of the methodology are tested in two floodplain areas in Northern Italy recently affected by floods. The results show that the methodology can provide an original and valuable insight of flood susceptibility and vulnerability processes.

Flood events, the frequency of which has shown an increasing tendency over the past

decades and consequences of which have made up 31 % of economic losses, have a very

special place in the area of natural catastrophes. And for these reasons solutions to the

question of flood protection are acquiring a wider international dimension and are

increasing pressure on the realization of the system-wide working of complex measures.

The transition from protection from flooding to complex flood management is reflected

most of all in directive 2007/60/EC on the assessment and management of flood risk. The

guideline strengthened the converging of national approaches to flood management and

control and likewise brought parallel development in the area of the assessment of flood

risks and management of flood risk of member states of the European Union.

Before the proposal of the methodology itself, a search of the literature for available

documents relating to flood risk, risk analysis, legal arrangement of flood risk management

and likewise of existing and developing approaches for assessing flood risk in Slovakia and

around the world was developed. The contribution of the work is the proposal of a

methodology for preliminary assessment of flood risk from flash floods, which can be used

when accomplishing the goals of directive 2007/60/EC, i.e. reducing the probability of

floods and reducing their potentially adverse consequences.

The aim of the work was expanding the set of scientific knowledge in the field of

assessment and management of flood risk in Slovakia and the world, and a proposal for

directing the management of flood risks with the goal of reducing the adverse effects on

human health, the environment and economic activities connected with floods. A goal so

conceived had a primary task, namely ‘‘Proposal of a methodology for the process of

preliminary assessment of flood risk—a methodological procedure for preliminary flood

risk assessment from flash floods with respect to the need for its updating following from

directive 2007/60/EC and its application in the conditions of a modelled territory’’
