Morphological characteristics of the Atibaia river flood plain, Campinas and Jaguariuna muncipalities, SP, Brazil
Alluvial plain is a complex and dynamic system situated near the base level of watercourses and is the result of sedimentation and erosion processes. It is an area of hydrological risk for urban and peri-urban occupation, due to seasonal floods. The Atibaia river plain is an extensive border area (a...

| Resumo: | Alluvial plain is a complex and dynamic system situated near the base level of watercourses and is the result of sedimentation and erosion processes. It is an area of hydrological risk for urban and peri-urban occupation, due to seasonal floods. The Atibaia river plain is an extensive border area (approximately 34 km2) within the municipalities of Campinas, Jaguariúna and Paulínia. It is located in the transition between the Peripheral Depression and the Atlantic Plateau. The plain forms a small sedimentary basin, formed above the sedimentary rocks of Itarare Subgroup, due the tapering of the river channel by diabase rocks downstream, and gneiss rocks upstream. It exhibits two terraces with paleomeanders and paleo-channels, old point bars and levees. Small elevations are present, and recent NW and SE migrations of meanders were recorded. Wetlands and swamps are areas where the groundwater reaches the surface, accumulates and flows slowly to the river. |
