The Zarumilla River is a river in South America that marks the border between Peru and Ecuador. It is named after the Peruvian town of Zarumilla.
It is part of the
Gulf of Guayaquil-Tumbes mangroves Sanctuary and its currents, sediments, and tides strongly influence the geomorphology of the area. It empties into the Gulf of Guayaquil
.
The largest towns on its banks are
Tumbes Region of Peru; both towns are connected by an international bridge. The water flows through a canal
as the river passes these populated areas. Pollution is a problem in this part of the river, as people from both countries discharge their waste into the canal.
Border issues
In 1998, during
El Niño, the river changed its course, moving 1 square kilometre of land into its eastern margin. Ecuadorians took advantage of this situation, saying that the river is the natural border
marker and therefore gives them rights in the affected area. The Peruvians argued that the area is sovereign Peruvian soil.
