We don’t know

Interview with Daniela Benfica, city engineer, Departamento de esgostos pluviais, April 2013, Porto Alegre

That’s what we study in hydrology. We had at the time this series here, we now have a bigger series, up to 2013. And we don’t know if we are in a very, very dry period inside a wet period, or if we are in a wet period inside a dry period.
We don’t know if this is representative of what happens with water, with rain and with flooding, it’s too short to know about that.
