Precipitation Assessment from the Point of View of the Data Availability for Purposes of Flood Modelling
Original language description
In this paper, the differences in total precipitation for two selected events on the catchment are assessed using data measured in a number of meteorological stations. The events were selected which caused significant raise of the discharge at the outlet of the catchment. Presented study was carried out for the catchment of Blanice River (Southern Bohemia). Data used for this purpose have hourly time step. The total catchment precipitation was calculated using Thiessen polygons based on station data and the exclusion of single stations was assessed. This analysis was carried out in order to demonstrate the influence of missing data from one station which can be caused for example by station failure. Furthermore, the analysis was focused on the variation of precipitation volumes when considering only single stations. The results show in general high spatial variability of rainfall but the influence of missing data from one station is not crucial when the network of gauging stations is dense enough. Analysis was performed by calculating the total volumes of precipitation on the catchment for different combinations of observed data which were compared to the volume of precipitation using all of them. The detail results demonstrate that there is a difference in calculated volumes in case of leaving out one of precipitation station but this difference is not very high. On contrary, there are very high differences in case of consideration only one station which means that in this case the uncertainty of modelled discharges would be too high for both analysed events. In general, the results can be concluded in a statement, that it is insufficient to use the data from only one station for modelling the catchment having area similar to the catchment used for presented analysis in comparable climatic conditions because it would result in large error in estimated precipitation volume.
