Abstract:

A disastrous torrent flood on the Vlasina River of 26 June 1988 was of unprecedented intensity in Yugoslavia. The catchment area affected by the catastrophe covered more than 1000 km² and the damage was estimated to one billion dollars. Those results indicated a need to find different analytical approach because, besides visible traces, the actual records of flood were sparse. Rain gauging stations in the zone affected most seriously were completely destroyed as well as water level gauges. Since the torrent flood computations on the base of flood traces are not reliable, the causes of flood occurrence and development of flood itself had to be reconstructed.
