Incidence of Natural and Anthropic Aspects in the Floods of Buenos Aires City. Floods inBuenos Aires city are the regions most severe environmental problem. They cause economic losses and a strongimpact on the populations daily life. Historical flood citys data is essential for the development of hydrologicmodels and for structural and non structural environmental decisions. This paper presents a detailed register offlood events occurred in Buenos Aires city between 1980 and 2005. During this period, 148 events took place, fromwhich 29 were extreme flood events. From the total events a 61.5% was caused by rainfall and a 38.5% bysudestadas (strong southeastern winds). Results show that geomorphology and flood frequency records arerelated: neighborhoods placed over the Estuarine Plain and Flood Plain show the highest values, whereas thoseplaced over the Interfluves and Laterals show the lowest flood frequency values. Information gathered shows thatanthropic aspects, as the presence of Villas and green spaces, cause biased results related to the sources thatregister flood events. The need of developing hydraulic models, which should consider the sudestada phenomenon,and the importance of regular controls carried on by appropriated organisms which register accurate information,are pointed.
