Abstract

This research aims to examine the Flood Control Strategy of Merauke City with the approach of existing drainage
conditions, vulnerability testing and spatial planning policies of Merauke City. The background of the research departs
from the increasing frequency of extreme rainfall and the threat of tidal flooding due to climate change and the
characteristics of coastal geomorphology that trigger higher flood risks. This research uses descriptive and quantitative
approaches. Data sources were obtained from primary data which were the results of interviews and field
observations while secondary data were obtained from relevant agencies. The results showed that the flood drainage
channel was not optimal, the vulnerability indicator of Merauke city was 2.2 on a scale of 4 with a moderate category,
and the impact of changes in the RDTR of Merauke city in 2023. The height of flood water in Merauke city is still low
(average 0.5 - 1m) but the flood area is increasing, especially in areas with high population density and low areas due
to land changes and residential development in infiltration / low areas. Flooding in the city of Merauke is due to high
rainfall and overflow of water from the drainage as a result of siltation in the drainage and damage to several
floodgates. The strategy to control flooding in Merauke city is by optimizing flood drainage channels and building
retention ponds, especially in coastal, densely populated and low-lying areas, as well as by spatial planning for the
protection of infiltration zones and water boundaries in changing land functions and increasing public awareness in
maintaining the cleanliness of drainage channels
