Geography

According to the Brazilian Institute of Geography and Statistics, Bauru’s municipal area spans km². Bauru’s terrain is predominantly undulating, with 64.71% of the territory characterized by rolling hills, while flat areas account for 23.85%. The city’s soils are primarily sandy, with low drainage density, a characteristic of the Western São Paulo Plateau, influenced by the region’s warm climate for much of the year. Predominant soil types include red-yellow latosol, found extensively, and red-yellow acrisol, common on steeper slopes, both with medium to sandy textures. Latosol areas are prone to large gullies. These soils are developed, stable, and well-drained but lose micro-aggregates under intense irregular occupation, leading to significant erosion. The terrain’s density directly affects drainage networks, which, in turn, can alter the surface configuration. Bauru’s main rivers are the Bauru River and the Batalha River. The Bauru River originates near the urban perimeter in the former Fazenda Fortaleza (now a subdivision in the Lagoa Sul neighborhood), flowing 42 km to join the Tietê River between Boraceia, Pederneiras, and Itapuí. The Batalha River, originating in Agudos, is a significant Tietê tributary, stretching 167 km. It supplies Bauru with water. According to the Center for Meteorological and Climatic Research Applied to Agriculture (CEPAGRI) at the State University of Campinas (UNICAMP), Bauru’s climate is classified as a tropical highland climate (Aw per the Köppen climate classification), prevalent in central-western São Paulo. It features dry, mild winters and rainy, warm summers, with the warmest month’s average temperature exceeding °C. Autumn and spring serve as transitional seasons. The annual rainfall averages approximately millimeters (mm),…
