Many rivermouths can be observed along the coast of West Africa. Furthest north is the Senegal River, marking the border between Mauritania (above) and Senegal (below).
Moving down the coast, the terrain appears mostly arid until the Gambia River is reached. The land surrounding both banks of the river belong to the Gambia, the smallest country in Continental Africa, while the land to the North, South and East is part of Senegal.
Continuing south along the coast, the Casamance River can be seen just north of the border between Senegal and Guinea-Bissau.
In Guinea-Bissau, two prominent rivers can be observed, the Cacheu River and the Geba River. The Geba is the most visible, as it has a wider mouth and its waters are tinged golden brown by sediments.
All of the rivers are spilling some quantity of sediments into the Atlantic Ocean. However, those in the wetter regions to the South are discharging a greater amount.
