Abstract

This article examines the characterisation of the Rota Wewa tank cascade system in the vicinity of Anuradhapura, Sri Lanka. Sedimentological analyses show that a precise age determination and the reconstruction of sediment and water fluxes as triggered by human-environment interactions are difficult. This is caused by the shallow character of the wewas leading to the steady redeposition of the tank sediments by wave motions during the wet season and agricultural use of the desiccated wewas during the dry season. Beyond, the sediments analysed allow to distinguish between the weathered parent bedrock and the overlying sediments
