CARACTERIZA O TEMPORAL E ESPACIAL DA PRECIPITA O NO ENTORNO DO MUNICíPIO DE S O GON ALO (RJ) CONSIDERANDO A SéRIE HISTóRICA DE 1968 A 2002

The lack of urban planning and the environmental characteristics of S o Gon alo (RJ) makethis municipality vulnerable to floods. In order to contribute to actions that reduce this problem,this paper has the objective to characterize precipitation on a space and time perspective,using rain data of precipitation stations in S o Gon alo surroundings. The annual precipitationanalysis, considering the historic series (1968-2002), identified three different periods withrain variability: 1968-1980, 1981-1996 and 1997-2002. It was verified a rainnig spatialvariation using annual precipitation and frequency of rain classes. Regarding the precipitationstations near to the drainage basins that converge to S o Gon alo or that was in the municipality,it was verified a great water contribution to flood formation in the city.
