About article:
LOW FLOW CHANGE ANANLYSIS IN SELECTED GAUGING STATIONS ON THE DANUBE RIVER. This paper is focused on the low flow change analysis in the measured daily flow data series. There is a strong need to have complete and exhausting information on the water regime of the Danube River in order to be able to generalize such information on the basis of long-term observations from the whole Danube territory. We use the database of the mean daily discharge of the Danube River. The first part of the paper describes the IHA (Indicators of Hydrological Alternations) software evaluating changes in the number of small, medium and large floods as well as of low flows and extreme low flows. The IHA statistics will be meaningful only when calculated for a sufficiently long hydrologic record. In the case of an abrupt change in the river basin, such as construction of dam or climate change, the IHA statistics can be used for identifying the flow change between two time periods, that before and after the impact. Nine gauging stations from the database of mean daily discharges on the Danube River were chosen for the analysis of low flow changes. The changes of daily flows during the time period of hydrological years on the Danube River at selected gauging stations are presented in the second part of the paper.
