Since the mid-Holocene, coastal plains of Kedah, Seberang Perai and Perak have grown at average annual rates of 4 metres and even of 11 metres in the vicinity of river mouths. These coastal plains host linear beach ridge sets parallel to the current shoreline, where frontal beach ridge sets rarely exceed 1.5 m high. Each of these beach ridge sets represents a period of still stand of the prograding coastline. In the past the still stands may have been caused by a combination of changing rates of natural processes, but since the 1700s these processes had also anthropogenic input. The plains between beach ridge sets were former shallow sea-beds or that of lagoons and their existence mark periods of more rapidly prograding shorelines.

Abstract

Since the mid-Holocene, coastal plains of Kedah, Seberang Perai and Perak have grown at average annual rates of 4 metres and even of 11 metres in the vicinity of river mouths. These coastal plains host linear beach ridge sets parallel to the current shoreline, where frontal beach ridge sets rarely exceed 1.5 m high. Each of these beach ridge sets represents a period of still stand of the prograding coastline. In the past the still stands may have been caused by a combination of changing rates of natural processes, but since the 1700s these processes had also anthropogenic input. The plains between beach ridge sets were former shallow sea-beds or that of lagoons and their existence mark periods of more rapidly prograding shorelines.
