This report has been prepared to provide information regarding appropriate sites and appropriate instruments for measuring ocean and coastal processes in Timor-Leste which are capable of providing information to determine the processes that influence water level variations at the coast, including the contribution due to sea level rise. After conducting a rapid assessment of the coastal environments of Timor-Leste, appropriate locations where tide and sea level rise instruments can feasibly be installed were determined. The recommendations regarding instrument placement and setup are based upon the most recent recommendations for organisations wishing to participate in the Global Sea Level Observing System (GLOSS). As such, these recommendations align with best international practice.
