Firstly, the volume of water in the reservoir before its breach was determined. The reservoir storage volume was estimated to be 14 807 m 3 . Then, we focused on the analysis of the hydrological regime in the wider Rudniansky Brook region. In order to derive the flood wave course from the rainfall, a series of 15-minute discharge from neighbouring water gauges measured by the Slovak Hydrometeorological Institute were analysed. In analysing the long-term trends of precipitation and temperature series we used data from the Banská Štiavnica meteorological station (period 1901–2020). In the second part, based on several field measurements after the flood event, we estimated the peak flows of floods from May 17, 2021 above the reservoir and under the reservoir. One hundred meters above the reservoir culmination reached 7.8 m 3 s -1 , under the reservoir it was between 80 to 100 m 3 s -1 . Finally, we reconstructed the course of the flood wave from the precipitation above the reservoir by hydrological analogy and by simple rainfall-runoff hydrological model NLC. The course of the breakthrough wave from the reservoir water just below the dam was determined to be triangular in shape so that the peak reached 90 m 3 s -1 and the volume was 15,000 m 3 .","PeriodicalId":321483,"journal":{"name":"Acta Hydrologica Slovaca","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122817738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Changes in flood wave characteristics (shape, volume, peak flow) may significantly affect the functionality of these structures. The study proposes a methodology for constructing design wave and flood hydrographs using discharge time series. A case study was carried out in the Little Carpathians watershed of the Parná River, above the profile of the Horné Orešany reservoir in Slovakia. The volumes and characteristic shapes of the flood waves with the maximum annual and seasonal discharges were determined using the Floodsep software. Subsequently, the T -year annual and seasonal discharges were estimated. Then, for pairs of the T year discharges and the associated volumes of flood waves, a joint probability distribution was constructed by copula functions. The associated volume of the T -year peak discharges was selected from the copula, and the probability of exceeding it was determined. Based on this analysis, a set of annual and seasonal control flood waves with the design maximum discharge, the associated volume with the selected probability, and the typical shape of the flood wave was constructed. This research provides satisfactory results for designing control waves necessary for assessing water structures with extreme loads and establishing a functional methodology for assessing other water structures in the region.","PeriodicalId":321483,"journal":{"name":"Acta Hydrologica Slovaca","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129364579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The flow rate fluctuations in two different streams in Slovakia are being investigated in this study. The study focused on an under-mountain and a lowland-highland river to investigate the low and peak flow periods and to identify the trends in monthly and annual mean flows for both rivers. Analysing daily mean discharge data from two different types of streams requires the use of a robust normalization approach to verify the comparability between the chosen streams. On both streams, a broad statistical low-flow analysis was performed over different study periods, as well as a hydrological drought analysis utilizing the water-bearing coefficient approach over the period 2010–2020. The evaluation for the foothill river in Slovakia demonstrates that snow melting has a significant impact on annual runoff in the spring months, and both rivers have a low flow period in August, September, and October. Despite the considerable variations in the catchment area, geographical, and hydrological characteristics, drought analysis for the years 2010 to 2020 found a lack of normality and a dry hydrological situation in both streams.","PeriodicalId":321483,"journal":{"name":"Acta Hydrologica Slovaca","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128888634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we evaluate the drought in terms of changes in hydrological characteristics for the 20-year period 2001– 2020. The evaluation of changes is based on a comparison of data for this period with the currently valid reference period 1961–2000 in 13 selected water-gauging stations. In the analysis of the occurrence of subnormal mean annual discharges ( Q r <90% Q a,1961-2000 ), in most of the evaluated stations, the percentage incidence of such years is higher in the period 2001–2020 than in the reference period. The distribution of runoff throughout the year in the period 2001–2020 in comparison with the reference period in most stations confirms the changes identified in the previous evaluation of the period 2001–2015, i.e. the transfer of part of the usual increased spring runoff to previous, winter months. An exception was water-gauging stations on streams in the mountainous areas of northern Slovakia, where changes are reflected to a lesser extent.","PeriodicalId":321483,"journal":{"name":"Acta Hydrologica Slovaca","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121095298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the first part of the study, the hydrological balance is processed in an annual step on the basis of measured series of average monthly flows from the Krupinica: Plášťovce; monthly precipitation totals on the Krupinica catchment area and average monthly temperatures in the catchment area. The hydrological balance in the monthly step was processed in the second part. Changes in water resources in the river basin over the three mentioned time subperiods were analyzed. The long-term annual precipitation total in the Krupinica River basin for the whole period was 660 mm, the annual runoff depth was 182 mm and the balance evaporation was 478 mm. A comparison of 30-year periods shows a significant decrease in the runoff of Krupinica – from 231 mm to 144 mm. This was even more pronounced in the runoff coefficient – it fell from 0.32 over 0.27 to 0.21 in the last period 1991–2020. In the third part, a simple regression relationship between runoff, precipitation and air temperature was derived to estimate the future development of the annual runoff from the basin. The relationship shows that a 100 mm decrease in precipitation in the Krupinica River basin will cause an average decrease of 52 mm in runoff. And an increase in the average annual temperature by 1°C in the Krupinica River basin results in a decrease in runoff of about 33.5 mm.","PeriodicalId":321483,"journal":{"name":"Acta Hydrologica Slovaca","volume":"237 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128621797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the dangerous natural phenomena with impacts on humans and the economy are floods. The Tisza River, which originates in Ukraine and flows further through Romania, Hungary, Slovakia, and Serbia, has repeatedly become a source of disasters for the population due to the devastating consequences of floods, which have been increasing in recent years. The purpose of this study is to analyze the long-term series of observations of the maximum water discharge on the rivers of the Tisza basin, within Ukraine. Using the methods of statistical analysis, tendencies in the time series of annual maximum water discharges were investigated, its temporal homogeneity was estimated also, as well as the significance of the trends. Using the method of residual mass curves, high-water and low-water periods were distinguished. We also obtained preliminary dependences of the maximum runoff modules on the catchment areas and their heights, which in the future can serve as a basis for the development of a regional calculation method for determining the maximum runoff of ungauged rivers in the region.","PeriodicalId":321483,"journal":{"name":"Acta Hydrologica Slovaca","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125343284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Heavy precipitation is defined as maximum precipitation total over five consecutive days (Rx5D) where a non-zero daily precipitation total must be recorded every day of selected 5-day period. Spatial and temporal distribution of multiday precipitation totals is affected by many factors, mainly by the processes taking place in the troposphere eventually represented by the synoptic scale atmospheric circulation and by the orographic diversity of the area, which together significantly affects distribution of precipitation in the selected area.
