“…According to CRED EM-DAT [46], Romania is one of the European countries most affected by floods. Flooding was responsible for 86% of the economic damage caused by natural hazards in the last 30 years in Romania [47].…”

“…[32] further explored the GFI approach to obtain a rapid estimation of floodwater level. Specifically, since paired values of h r and A r are generally not available to calibrate the hydraulic scaling relationship of Equation ( 2), the authors suggest the GFI can be computed by estimating the exponent n from literature values (see, e.g., [47]) and assuming the coefficient a using the threshold calibrated with the linear binary classification. In particular, the coefficient a can be obtained as shown in Equation ( 3):…”

Large-scale flood risk assessment is essential in supporting national and global policies, emergency operations and land-use management. The present study proposes a cost-efficient method for the large-scale mapping of direct economic flood damage in data-scarce environments. The proposed framework consists of three main stages: (i) deriving a water depth map through a geomorphic method based on a supervised linear binary classification; (ii) generating an exposure land-use map developed from multi-spectral Landsat 8 satellite images using a machine-learning classification algorithm; and (iii) performing a flood damage assessment using a GIS tool, based on the vulnerability (depth–damage) curves method. The proposed integrated method was applied over the entire country of Romania (including minor order basins) for a 100-year return time at 30-m resolution. The results showed how the description of flood risk may especially benefit from the ability of the proposed cost-efficient model to carry out large-scale analyses in data-scarce environments. This approach may help in performing and updating risk assessments and management, taking into account the temporal and spatial changes in hazard, exposure, and vulnerability.

“…The analysis of the social effects and direct, tangible damages was based on quantitative data, including the event flood reports of the County Committees for Emergency Situations and County Prefect's Houses. Such investigations require normalization of event loss values (goods and assets values and the cost of repairs/replacements) for changes in inflation (Barredo, 2009;Arghiuş et al, 2011). Thus, using the annual average values of the implicit price deflator, an adjustment of damage costs at the values of goods and services in the year 2005 was performed.…”

Abstract. Flash flood disasters are very rare in the Transylvanian Depression. In the last decades just three events were signalled in the study area, all of them during the last 10 yr. The flash floods occurring in the study area during the last decade had a significant impact on several localities situated at the Transylvanian Depression border. Based on the post flash flood investigation, the present study intends to find out the main characteristics of the flash-floods and the causes that have led to disasters in a region rarely affected by such kind of events. Analyzing the hydrological data, has been seen that the maximum intensity of the flash floods was observed in the upper and middle basins. By comparing the unit peak discharges from the studied region with other specific peak discharges related to the significant flash floods from Romania, it was noticed that the events from the Transylvanian Depression have moderate to low intensity. On the other hand, the results showed that beside high stream power and unexpected character common to flash floods, the inappropriate flood risk management measures increased the dimension of negative effects, leading to tens of life losses and economical damages of tens million dollars.

“…Flood expert: Some studies have undertaken temporal trend analyses on flood damage data (e.g. Pielke and Downton 2000, Llasat et al 2008, Barredo 2009, Arghius et al 2011, Pérez-Morales et al 2018. Additional literature is available on trends in damage due to hydro-meteorological events, including floods (e.g.…”

For the development of sustainable, efficient risk management strategies for the hydrological extremes of droughts and floods, it is essential to understand the temporal changes of impacts, and their respective causes and interactions. In particular, little is known about changes in vulnerability and their influence on drought and flood impacts. We present a fictitious dialogue between two experts, one in droughts and the other in floods, showing that the main obstacles to scientific advancement in this area are both a lack of data and a lack of commonly accepted approaches. The drought and flood experts "discuss" available data and methods and we suggest a complementary approach. This approach consists of collecting a large number of single or multiple paired-event case studies from catchments around the world, undertaking detailed analyses of changes in impacts and drivers, and carrying out a comparative analysis. The advantages of this approach are that it allows detailed context-and location-specific assessments based on the paired-event analyses, and reveals general, transferable conclusions based on the comparative analysis of various case studies. Additionally, it is quite flexible in terms of data and can accommodate differences between floods and droughts.
