Abstract. With reference to the rockfall risk estimation and the planning of rockfall protection devices one of the most critical and most discussed problems is the correct definition of the design block taking into account its return period. In this paper, a methodology for the assessment of the design block linked with its return time is proposed and discussed, following a statistical approach. The procedure is based on the survey of the blocks already detached from the slope and accumulated at the foot of the slope and the available historical data.

Abstract. Flood risk poses a major problem for insurers and governments who ultimately pay the financial costs of losses resulting from flood events. Insurers therefore face the problem of how to assess their exposure to floods and how best to price the flood element of their insurance products. This paper looks at the insurance implications of recent flood events in Europe and the issues surrounding insurance of potential future events. In particular, the paper will focus on the flood risk information needs of insurers and how these can be met. The data requirements of national and regional flood models are addressed in the context of the accuracy of available data on property location. Terrain information is generally the weakest component of sophisticated flood models. Therefore, various sources of digital terrain models (DTM) are examined and discussed with consideration of the vertical and horizontal accuracy, the speed of acquisition, the costs and the comprehensiveness of the data. The NEXTMap DTM series from Intermap Technologies Inc. is proposed as a suitable DTM for flood risk identification and mapping, following its use in the UK. Its acquisition, processing and application is described and future plans discussed. Examples are included of the application of flood information to insurance property information and the potential benefits and advantages of using suitable hazard modelling data sources are detailed.

In this paper the role and importance basic problems of the crisis answer system of the flood economic damage decrease are considered. The phases of that system and estimate procedure of flood risk are defined, by using scientific methods analysis, synthesis and description. The basic aspects of the economic damage posible decrease are analysed, by using the case study example. The main importace of the flood prevention is emphasized, as a proposal for the crisis management practice. The investment importance of the flood prevention, as the economic justifiable, is emphasized, instead of answer crisis and economic demage restoration investment. The main specifications of the new approaches in the filed of of the floods defence are showed.

Society demands higher safety levels, including those actions related to urban planning and protection against natural hazards and manmade threats. Therefore, authorities respond to these demands through new regulatory and operational frameworks to cope with existing and future risks. The Spanish regulatory framework regarding flood risk management, based on the European context, defines the required procedures for emergency management, involving all authorities responsable for civil protection and urban planning. This framework requires all municipalities at medium or high flood risk to develop and implement local action plans against flood risk (PAMRI, by its acronym in Spanish), which must include a risk estimation, analysis and evaluation, along with the description of actions for a risk-informed urban planning and emergency management. The City Council of Oliva developed the corresponding plan, approved by the regional government in June 2016, including new aspects such as the figure of the Technical Director, and a comprehensive and quantitative flood risk analysis to support decisionmaking on emergency management and planning.

Abstract This study proposes a method for estimating the flood risk in a tropical basin. The novelty consists of using two dynamic variables represented by the precipitation and the land use and land cover (LULC) to obtain the effective rainfall and its exceedance probability. The flood risk is determined by using deterministic methods depending on the exceedance probability of effective rainfall. Two time series of precipitation were involved. The first precipitation time series was used to prove the method corresponding to the months of the rainy season obtained from 58 gauging stations during the period 1980–2000. The second precipitation time series was applied for the validation stage of method corresponding to the period 2015–2018. In the validation stage, it has been found that there is a slight difference between the principal component N° 1 in the first time series with respect to the second time series. The method represents a contribution to determine the spatio-temporal distribution of flood risk that allows decisions to be taken to achieve preventive measures that contribute to the protection of human beings and goods.

<div> <p>What is your relationship with river? This was the central question posed by a series of creative practice workshops with scientists and local authorities who worked with complex flood risk management issues. Many of the flood mitigating solutions offered to managers are based on scientific methods to control and reduce river flooding. Scientific methods not only provide a sense of control towards river dynamics, but also develop a sense of security for people to feel safe from water. Because of climate change, flood events are increasing globally and some countries, like Scotland, are seeking to expand the possibilities of coping with extreme weather through broader, more holistic ways to mitigate flooding.</p> </div><div> <p>The aim of this study was to bridge rational knowledge often associated with scientific methods and the tacit knowledge that might emerge through participative art. The creative potential of art and participation in art practice was employed in collaboration with scientists and policy makers to inform future solutions towards flood mitigation.</p> </div><div> <p>The research used the theoretical premises described in what Irwin (2013) describes as a/r/tography: “drawing upon the professional practices of educators, artists, and researchers, it entangles and performs what Deleuze and Guattari (1987) refer to as a rhizome, an assemblage of objects, ideas, and structures that move in dynamic motion performing waves of intensities that create new understandings.” (p.199). Unlike the outcome and target driven aims of scientific methodology, these “waves of intensities” are crucial to understanding the form of intersubjective work which is crucial for art and creativity in art practice, because this is where affective transformation of meaning and understanding happens, through sensing, feeling and perceiving.</p> </div><div> <p>In the case of these creative practice workshops, the transformation that was explored was a shift from anthropocentric thinking about water to non-anthropocentric thought, achieved through sensing, feeling and perceiving. The creative practice workshops at the Scotland flood management conference 2020 were part of a larger process, where the intent was to initiate a transformative process that would work towards developing different ways of thinking in terms of Flood Risk Management. The process began with an artistic engagement with the river and the development of underwater film of rivers. This was followed by two participatory workshops. The next step consisted of an artistic response to the creative process undertaken by the participants. The last step was an engagement with water management policy makers. This will be further discussed in terms of a transformative process between artist and scientist.</p> </div>
