Abstract

The paper investigates compound fooding from waves, sea surge and river fow in northern Jakarta, Indonesia, which is a global hotspot of fooding, by combining process-basedcoastal and river models. The coastal hydrodynamic modelling of Jakarta Bay in Indonesiashows that coastal storms can lead to a...
