Abstract
By a News Reporter-Staff News Editor at Robotics & Machine Learning DailyNews Daily News – There are several factors that play an important role in the development of floods:air temperature, soil moisture, sn ow depth, and the daily precipitation in the days before a flood. Inorder to be tter understand how individual factors contribute to flooding, UFZ researchers e xamined morethan 3,500 river basins worldwide and analysed flood events between 1981 and 2020 for each of them.The result: precipitation was the sole determin ing factor in only around 25% of the almost 125,000 floodevents. Soil moisture was the decisive factor in just over 10% of cases, a nd snow melt and air temperaturewere the sole factors in only around 3% of cases. In contrast, 51.6% of cases were caused by at least twofactors. At around 23%, the combination of precipitation and soil m oisture occurs most frequently.
