Beach erosion: case studies on the East African Coast

Abstract

Marine erosion of late Holocene beach deposits is a common problem on the equatorial coasts of the western Indian Ocean, damaging or threatening tourism-related investment and communication infrastructure. The problem is acute in Tanzania, both on the mainland in the vicinity of Dar-es-Salaam and on the islands of Zanzibar and Pemba. In Kenya erosion affects resort developments both north and south of Mombasa, while in the Seychelles it affects particularly the islands of Praslin and La Digue.
