Abstrak

A hydrometeorological disaster is an event or series of floods, landslides, ecosystem damage, land degradation, hurricanes, and droughts, which can threaten people's lives. The current climate change is also allegedly causing an increase in hydrometeorological disasters. The distinctive characteristic of the estuary is the confluence of river and sea flows, increasing the potential for hydrometeorological disasters. Therefore, it is necessary to mitigate hydrometeorological disasters in the Ayung River Estuary to reduce the negative impacts that can occur due to hydrometeorological conditions. This research is a descriptive quantitative research. Meteorological data obtained from satellite data is used to see the meteorological characteristics of the Ayung River Estuary. Based on the results of the analysis, it is known that several hydrometeorological conditions in the Ayung River estuary area show potential hydrometeorological disasters, such as an increase in maximum wind speed reaching 1.5 times the average speed, an increase in temperature ranging from 6-8°C from the average temperature and conditions There is daily rainfall that reaches more than 100 mm/day. Mitigation efforts that can be carried out in the Ayung River Estuary can be carried out with many actions such as structural, non-structural and potential nature-based solutions (blue, green and hybrid infrastructure approaches).
