Given the increasing impacts of flooding in Jakarta, methods for assessing current and future flood risk are required. In this paper, we use the Damagescanner-Jakarta risk model to project changes in future river flood risk under scenarios of climate change, land subsidence, and land use change. Damagescanner-Jakarta is a simple flood risk model that estimates flood risk in terms of annual expected damage, based on input maps of flood hazard, exposure, and vulnerability.

Writing in Nature Climate Change, Lin and colleagues show that the combined effect of storm climatology and sea-level rise will greatly shorten surge-flooding return periods. Future climate effects may cause the present-day 100-yr and 500-yr surge flooding in New York City (NYC) to occur every 3–20 yrs and every 25–240 yrs, respectively. (Correspondence)
