Abstract
The idea of this paper is to present the main results of a comprehensive analysis of the Sava and Drina low water discharges in the area of the Drina river mouth. The paper presents the quantitative characteristics of low discharges that are generally used as a basis for designs of the majority of water management and hydrotechnical facilities. The particular focus is a detailed analysis of the length of low discharge periods below the initial discharges, which were determined for selected durations from the curves of average daily discharge durations. A new approach was applied which, in addition to the classic probabilistic analysis of minimum annual and minimum average monthly discharges, also includes the analysis of the length of continuous low discharge periods with discharges lower than the discharges of characteristic durations, their intra-annual distribution and representation. The basic data used for the calculation of low discharges are the official data of the Croatian Meteorological and Hydrological Service from Zagreb (DHMZ) and the Republic Hydrometeorological Institute of Serbia from Belgrade (RHMZ) at the hydrological stations (HS) Županja and Sremska Mitrovica on the Sava River and Radalj on the Drina River.
