(EN): Study of historical flood events is important as a base for hydrological studies, as well as for proposal offlood control measures and real-time flood forecasting helping forecasters to support their decisions. This work deals with proposal of Flood Archive (databa of flood event) and its app|ication in the scope offlood protection ofotava river basin to Písek water gauge. The objective was to pťopose Archive of historical floods containing information about casual synoptical situation, connected weather phenomena (precipitation, temperature) and runoff response. Flood formation mechanism in otava river basin was described using this Archive. A forecasting technique based on analogue method was designed. This technique searches historical records for flood events of similar causes and estimates possible development of runoff response. Archive consists of 72 flood events that occurred between I 890 and 2006 and their peak flow in all cases exceeded given threshold discharge in Písek closin. profile (lO-year return period for 1890-196,l and ,l -year return period for 1961-2006). Available historical data was gathered and processed inÍ.lgraphic form (maps, graphs' tables). F|ood Archive is part of the di ssertation thesis. The most outstanding features of flood formation mechanism in otava river...
