The Río Tumbes , in the Ecuadorian upper reaches Río Puyango , is an approximately 205 km long tributary of the Pacific Ocean , which in sections forms a border river between Peru and Ecuador. With headwaters, the total length is about 250 km.
Source rivers
The headwaters of the Río Puyango is located in the southwest of Ecuador in the western foothills of the Andes . The river arises 14 km southeast of the small town of Balsas at the confluence of the Río Pindo (right) and Río Yaguachi (left). The Río Pindo , the main source river of the Río Puyango, arises itself 20 km upstream at the confluence of the Río Luis and Río Ambacolas and after 6 km takes the Río Amarillo on the right side . This in turn takes up the important tributary Río Calera 5 km above the mouth on the right.
River course
The Río Puyango initially flows to the west, later towards the west-southwest. It separates the northern province of El Oro from the southern province of Loja . Not far from the course of the river, near river kilometer 150, is the " Petrified Forest of Puyango " with fossil tree trunks. Between river kilometers 148 and 104 the river forms the state border with Peru. The Peruvian province of Zarumilla is on the right bank of the river for the top 8 kilometers . The Tumbes National Reserve is also located on the right bank of the river . This is followed by the Cerros de Amotape National Park , which the river later flows through. At river kilometer 104 the Quebrado Cazaderos meets the river coming from the south. Then the river, now called Río Tumbes, flows through the Peruvian province of Tumbes in a northerly direction. 20 km above the mouth, the river passes the city of Tumbes on the right bank of the river . Shortly thereafter, a mouth arm splits off on the left. The main river finally reaches the sea 8 km north of Tumbes and 15.5 km southwest of the Peruvian-Ecuadorian border. The estuary is in the extreme south of the Gulf of Guayaquil .
Hydrology
The Río Tumbes drains an area of about 5400 km². 3694 km² of this are in Ecuador. The mean discharge is around 108 m³ / s.
