The Malacca Straits is full of land-derived sediment. Southwest Coast, Timor, Indonesia The dry hilly countryside of south-western Timor shows up under fleecy cumulus clouds. The hills are partly bare and under erosion, contributing considerable sediment to the rivers. The rivers are seasonal with bars and islands in their channels. The straightness of the coast suggests geological control and a steep offshore slope.
Heavy surf is visible.
The depositional landscape at the mouths of the large rivers suggests recent alteration of the coastlines and river diversion. An impressive array of internal waves in the Andaman Sea captured in one pass of ERS-2 on 11 February 1997. The Mekong flows through a folded structure which partly controls its geometry as shown in near right-angled bends. As the Mekong cut through this structure, rocks became exposed in its channel forming rapids, and the river forced its way through constrictions. This is the mouth of the Haringhata River, in the southern Khulna-Patuakhali area.
