Characterization and morphometry of prone and affected watersheds by hydro-geomorphological processes in the Serra do Mar Mountain Range, southeastern Brazil: foundation for planning and mitigation actions.

Data: shapefile, tables, and kmz files. SHAPEFILES - Dataset with watersheds mapped in the Serra do Mar Paulista Region in the follow cities: Ubatuba (Abbvr. WU) Caraguatatuba (Abbvr. WC) São Sebastião (Abbvr. WSS) Bertioga (Abbvr. WB) Santos (Abbvr. WS) Praia Grande (Abbvr. WPG) Cubatão (Abbvr. WCUB) São Vicente (Abbvr. WSV) Itanhaém (Abbvr. WITA) Peruíbe (Abbvr.

WITAO) - Each shapefile contain information about altitude (min., max, and mean), area (km²), and length (km). - Debris-flow Inventory shapefile. 2. TABLES Tables for the watersheds mapped in each cities also contain information about the morphometric parameters (melton ratio, basin relief, and relief ratio). Debris-flow inventory information.
