JAGUARIBE: THE MAIN RIVER CROSSING MY HOME CITY

'Jaguaribe'  means 'where the jaguar drinks water' (jaguar in Brazil is better known as 'onça' = ounce).
This river has a historical importance for our region, and Brazil for Brazil as well. Through the Jaguaribe river Dutch soldiers invaded Paraíba state (1630 and following years until 1654 Dutches established in northeast Brazil).

This short video shows a very common and frequent problem in the river Jaguaribe, which crosses João Pessoa, the capital of Paraíba state, northeastern Brazil.

This tract of the river is just around 1 m under the road and its surface is completely covered by the 'common water hyacinth' (Eichhornia grassipes) ['aguapé' or  'baronesa', in Portuguese]; an aquatic plant native to the Amazon basin. This plant is often considered a highly problematic invasive species outside its native range. The water hyacinth is creating conditions for bed aggradation, directly caused by deforestation on the river banks. So, the dredge spoil and the water hyacinth should had been removed before the rainy period, which has just started.

It is not difficult to predict flood, in case such removal is not performed.

Flooding happens every year during our rains of autumn and winter on the coast of northeastern Brazil.
