Estuaries of the Gambia and Geba Rivers, West Africa – February 16th, 201213.4N 16.5W
This wide-swath ASAR image shows rivers flowing into the Atlantic Ocean along the west coast of Africa. The river with the very wide mouth near the center right is the Gambia River. It runs 1,130 kilometres (700 mi) from the Fouta Djallon plateau in north Guinea westward through Senegal and The Gambia to the Atlantic Ocean at the city of Banjul (visible as a white area on the coastline). About 100 km from its mouth it gradually widens to over 10 km wide where it meets the sea.
Another wide estuary can be observed near the center of the bottom edge: the mouth of the Geba River. It rises in Guinea, passes through Senegal, and reaches the Atlantic Ocean in Guinea-Bissau, for a course of about 340 miles (550 km) in total length. After passing by Geba town and Bambadinca, the river broadens into a wide estuary below Xime (where it is joined by the Corubal River), with a total width of about 10 miles (16 km) at Bissau.
