                         of S{\~a}o Louren{\c{c}}o do Sul, located in the south of the 
                         state of Rio Grande do Sul, 191 km from Porto Alegre, was reached 
                         by concentrated rains between the night of March \$9^{th}\$ and 
                         the morning of March 1\$0^{th}\$ that caused a flood episode, 
                         flooding a considerable part of the city. About 20 thousand people 
                         were affected by the flooding and around 500 had to wait under bad 
                         weather for rescuing. Eight districts were flooded and around 300 
                         families were islanded and more than 50\% of the city especially 
                         the urban area was covered by water between 2.5 and 3 meter high. 
                         The city declared public emergency on March 1\$0^{th}\$, 2011 
                         through Decree \$n\$3437. Two bridges of the BR-116 were 
                         submerged during the early morning of March 1\$0^{th}\$ along km 
                         471 and km 468 between the cities of S{\~a}o Louren{\c{c}}o do 
                         Sul and Turu{\c{c}}u. This study aims to analyze the flash 
                         flooding occurred in the municipality of S{\~a}o Louren{\c{c}}o 
                         do Sul specially in the stream basin of S{\~a}o Louren{\c{c}}o 
                         in the period of 9 to 11 of March, 2011, using geotechnologies. 
                         The specific objectives are identify in this city the main 
                         characteristics that contribute to flood events, characterize the 
                         features of the stream basin of S{\~a}o Louren{\c{c}}o that 
                         contributed to the flooding and evaluate the damage caused by the 
                         flooding in the city of S{\~a}o Louren{\c{c}}o do Sul. The 
                         municipality of S{\~a}o Louren{\c{c}}o do Sul is located in the 
                         southeast of the Rio Grande do Sul State, in the right margin of 
                         Laguna dos Patos, latitude of S3\$1\$2155\textquotedblright 
                         and longitude of W5\$1\$5842\textquotedblright in an altitude 
                         of 19 meters. In this study were used the images of the satellite 
                         GOES 12, in a total of 36 images referring to the period of 
                         09:00AM of March \$9^{th}\$ to 8:00PM of March 1\$1^{th}\$, 
                         2011; LANDSAT5/TM images, path 221 row 82, bands 3, 4 and 5, of 
                         April 2\$3^{rd}\$ , 1995 and April 1\$6^{th}\$, 2010; Landsat

                         and land shape) of the project TOPODATA derived from SRTM, field 
                         data from: interviews with the affected residents, measures of GPS 
                         points of the water marks levels on facades of buildings, 
                         coordinates of the bridges affected by the flooding, coordinates 
                         of location of pluviometers, photographs of the affected areas. 
                         Maps were generated to the S{\~a}o Louren{\c{c}}o do Sul 
                         Municipality and stream basin of S{\~a}o Louren{\c{c}}o and maps 
                         of drainage, land use and land cover, relief, vertical and 
                         horizontal curvature, land shape, declivity, measures of the width 
                         of the stream channel of S{\~a}o Louren{\c{c}}o, location of the 
                         affected bridges by flooding and location of pluviometers. The 
                         flash flooding event occurred in S{\~a}o Louren{\c{c}}o do Sul 
                         was originated by intense rainfall concentrated in a short period 
                         of time. The land use and land cover in addition to the relief and 
                         declivity allies to concentrated rain contributed to enhance the 
                         flooding event. Social and economic losses in this city were 
                         considerable, especially in tourism, one of the main source of 
                         income of the city, the satellite data were important to identify 
                         the characteristics and the stream basin that contributed to the 
                         flash flooding event.",
