“…In the case of the Fosso Marina Grande River [103], on the other hand, the effects on the shoreline evolution are modest as the beach of Scilla is a pocket beach. Instead, the flood events described above were often coupled by high solid transport, causing debris flows that also obstructed part of the waterfront and roads adjacent to the river [104].…”

In the second half of the twentieth century, after the end of the Second World War, a considerable anthropogenic pressure was observed in most of the Mediterranean territories. This process has caused the expansion of existing settlements and the construction of numerous new towns, often located very close to rivers. A frequent consequence of this process is the transformation of several rivers through planform changes, narrowing, channelization and culverting to recover spaces where inhabited centers expanded, and the construction of structures interacting with rivers. This issue is very important in territories such as the Metropolitan City of Reggio Calabria, in southern Italy, which is an interesting case study due to the considerable anthropogenic pressures observed in the last 70 years. The main goal of this paper is to evaluate the effects of anthropogenic pressure in the last 70 years on some rivers of the Metropolitan City of Reggio Calabria in terms of the following issues: planform changes, channelization, culverting, and the presence of structures and infrastructures interacting with rivers. The specific goals of this paper are the quantification of the effects of anthropogenic pressure on the rivers of the study area analyzing sixteen parameters, the identification of possible conditions of hydraulic hazard through the analysis of past events, and the proposal of structural and non-structural mitigation interventions. In many rivers of the study area, the significant effects of anthropogenic pressure are visible through rivers that pass above highways, barred rivers, rivers replaced by roads and numerous crossing roads with a missing levee.

“…This is also reflected by large number of studies focusing on extreme precipitation, flash floods, flood protection; as e.g. seasonal characteristics of flood regimes across the Alpine-Carpathian range (Parajka et al, 2010), flash floods in urban areas: Case studies in region Calabria (Italy) (Franco et al, 2018), etc. The Western Slovakia is often affected by short-term rainfall during the summer period, these precipitations have a short duration with high intensity.…”

Štúdia sa zameriava na analyzovanie budúcich zmien v charakteristikách krátkodobých úhrnov dažďov v oblasti západného Slovenska. Analyzované boli zmeny v sezónnosti, trendoch a škálovacích koeficientoch pre určenie návrhových hodnôt intenzít dažďov v 3 vybraných staniciach a to Bratislava, Hurbanovo a Myjava. Pre analýzu boli použité reálne namerané hodnoty úhrnov za obdobie 1995-2009 a úhrny zo scenára CLM za obdobie 2070-2100. Testovanie špecifických výdatnosti bolo vykonávané na trvaniach 60 až 1440 minút. Pre odhad sezónnosti bola použitá metóda Burnovho vektora. Pre analýzu zmien trendov bol použitý Mann-Kendallov test. Záverom práce bolo určenie škálovacích koeficientov jednoduchým škálovaním a následné určenie návrhových hodnôt úhrnov dažďov. Výsledky analýzy poskytnú bližšie informácie o budúcich zmenách, ktoré môžeme očakávať na konci storočia. KĽÚČOVÉ SLOVÁ: úhrn zrážok, intenzita krátkodobých dažďov, Burnov vektor, Mann-Kendallov test trendu, jednoduché škálovanie FUTURE CHANGES IN SEASONALITY AND SCALING EXPONENTS OF SHORT-TERM RAINFALLS IN THE WESTERN SLOVAKIA USING CLM SCENARIO. The study focuses on the analysis of the future changes in characteristic of short term rainfall in the region of Western Slovakia. The analysis was performed for 3 climatological stations namely Bratislava, Hurbanovo and Myjava. For the analysis, the real measured rainfall depths for the period 1995-2009 and the rainfall depths from CLM scenario for period 2070-2100 were used. Analysis was performed for rainfall durations 60 up to 1440 minutes. The Burn´s vector methodic was used for estimation of seasonality changes. For the trend testing the MannKendall test was used. Finally scaling exponents were estimated by using simple scaling method and IDF lines were derived for the analyzed periods. The results of the analysis will provide further information about future changes that we can expect at the end of the century.

“…Borga et al [12] defined flash floods as the result of extreme rainstorms in small source basins, which depend on the correlation among rainfall distribution, landform, and hydrological factors, and may lead to geological disasters such as debris flow and landslide. Some scholars believe [13] that flash floods are short-duration and high-intensity precipitation, usually occurring in small basins, characterized by time concentration and poor water storage capacity. Due to the influence of topographic and climatic characteristics, some areas are particularly prone to flash floods and environmental risks.…”

Flash flood is one of the extremely destructive natural disasters in the world. In recent years, extreme rainfall events caused by global climate change have increased, and flash flood disasters are becoming the main types of natural disasters in the world. Due to the characteristics of strong suddenness, complex disaster-causing factors, great difficulty in prediction and forecast, and the lack of historical data, it is difficult to effectively prevent and control flash flood disaster. The early identification technology of flash floods is not only the basis of flash flood disaster prediction and early warning, but also an effective means of flash flood prevention and control. The paper makes a meta-analysis and visual analysis of 475 documents collected by the Web of Science Document Platform in the past 31 years by comprehensively using Citespace, Vosviewer, Origin, etc. We systematically summarize the research progress and development trend of early identification technology of flash flood disasters from five key research subfields: (1) precipitation, (2) sediment, (3) sensitivity analysis, (4) risk assessment, (5) uncertainty analysis. In addition, we analyze and discuss the main problems encountered in the current research of several subfields and put forward some suggestions to provide references for the prevention and control of flash flood disasters.
