Fluvial Hydrochemistry at East Bahia Watersheds [Tipologias Hidroquímicas das Bacias Hidrográficas do Leste da Bahia]

The huge hydrochemical rivers typologies result from the interactions of natural physiographic aspects and theland uses at the watersheds. At the Southern State of Bahia, a group of small watersheds presents different naturallandscapes and anthropic activities, which impose the existence of diverse hydrochemical signatures at the rivers basin ofthat area.
