Floods are the most frequent natural disasters and cannot be prevented. However, we can mitigate their consequences by implementing flood protection measures, which have to be economically sound. Therefore, when planning such measures, we have to know how to reduce the damage caused by floods and increase the actual benefits of the implemented measures. In the presented project, we upgraded the existing unified method for Slovenia. This method covers flood damage in different sectors (people and health, cultural heritage, natural environment, residential, agricultural and business sectors). For each of the sectors, a simple equation is used to calculate the damage cost, taking into account the strength, duration and dimension of the expected flood event with different return periods as well as exposure, vulnerability and values of the exposed elements in the targeted area. To estimate these values, both data from the census and market values were used. Using the proposed methodology, an application was developed based on the geographic information system. According to their type, the input data are based on three main forms: point, (poly)line, and (multi)polygon. Separate databases were established for each type of data. The developed application was tested in three flood areas in Slovenia. According to the results, it was adjusted for use by various groups of users.

The paper present results of the research program for the development of methodology and application for assessing the benefits of constructional and non-constructional flood risk reduction measures in Slovenia. This method covers flood damage in different sectors, cultural heritage, natural environment, residential, agricultural and business sector.

According to their type, the input data are based on three main forms: point, line, and polygon. For each type of data separate databases were established. The developed application was tested for three flood areas in Slovenia. According to the results it was adjusted to be used by various groups of users. For now, this application enables calculation of annual expected damage for the territory of the Republic of Slovenia. However, with an appropriate modification and adjustments of the methodology and KRPAN (depending on the available data in other countries), both the methodology and application could be transferred to other countries.

The paper presents the operation of the application KRPAN, which enables the calculation of the benefits of constructional and non-constructional measures to reduce flood risk. The results can serve as a support for assessing and comparing the benefits of the envisaged flood protection measures in the procedures of preparing the economic part of the investment documentation in the field of public finances. The application is based on the upgraded and supplemented method for assessing the benefits of constructional and non-constructional measures to reduce flood risk, which was developed in 2014 at the Water Institute of the Republic of Slovenia. The upgrade of the method and the development of the computer application took place under the Target Research Project V2-1733, which was financed by the Public Agency for Research of the Republic of Slovenia and the Ministry of the Environment and Spatial Planning.

The paper presents the preliminary results of the research program for the development of methodology and application for assessing the benefits of constructional and non-constructional flood risk reduction measures in the Republic of Slovenia for the preparation of investment documentation. When planning protection measures, the basic goal is to reduce the damage that the flood could cause and maximize the actual benefit of the implemented measures, which is evaluated as the difference between the expected damage before the implemented measure and the expected damage after its implementation. These measures can be of a physical nature with the introduction of construction facilities, but they can also be purely organizational in nature with the introduction of non-constructional measures. The first goal of the project is to upgrade the initial method, IzVRS (2014), to assess the benefits of constructional and non-constructional measures to reduce flood risks. The second goal is to create an application based on a geographic information system, through which the available location data in space are taken into account in the methodology for assessing the benefits of the measure. The method and application make it possible to assess the benefits of both constructional and non-constructional flood risk reduction measures, taking into account material and non-material damage for four groups of endangered persons: human health, the environment, cultural heritage and economic activities. The applicability of the method and application will be tested in three floodplains in Slovenia.
