The Zarumilla River is a river in South America, part of which forms the border between Peru and Ecuador. It is named after the town of Zarumilla in Peru.
The largest towns on the riverbank are Huaquillas in Ecuador and Agua Verde in Tumbez, Peru. Both towns are connected by an international bridge. When rivers pass through these densely populated areas, they flow through canals. Because the people of the two countries discharge their waste into the canal, this part of the river is seriously polluted.
Landscape: These ships are in Ecuador, while the Peruvian side of the border (right) is uninhabited. It is part of the Guayaquil-Tambes mangrove reserve, and ocean currents, sediments and tides strongly affect the landform of the area. It is discharged into the Guayaquil Bay.
