The catchment area of Curitiba consists of rivers and streams that cross the city in different directions, grouped in six river basins.
The main rivers that form the city's watershed are: Atuba River, Belém River, Barigüi River, Passaúna River, Ribeirão dos Padilhas and the Iguaçu River, all with characteristics of dendritic drainage.
Curitiba has been working since the 1970s on alternatives to minimize the negative impacts of urbanization on rivers.
An example is the construction of parks along the rivers with artificial lakes, which absorb and retain water for longer periods of time, minimizing floods.

After many studies of local water flows, most rivers were found to be subject to a canalization process.
Other alternatives developed to minimize the negative effects of urbanization are the implementation of programs for environmental education, inspection and monitoring, elaboration and application of legislation and infrastructure works.
