evaluation, drainage system, MeraukeAbstract
Merauke city suffers flooding in almost every rainy season, which endangers the environment and disturbspeople's activities. One of the worst floods happened in 2019, where flooding damaged vegetables and crops, impacted
the city's economy, and later caused economic inflation. Therefore, a study evaluating the drainage system in Merauke
city is needed to overcome this issue. This study was conducted through a field survey and literature study with data
that varies from hydrological, elevation, and hydraulics data. Hydrological data includes yearly rainfall data, and
hydraulics data consists of the drainage network and designs. This evaluation will then result in the normalization of a
drainage system. This study found that the capacity of the current drainage system is 10.815 m3/s, where this drainage
capacity cannot accommodate the amount of flood discharge plan. Also, the existing drainage system is missing a
component that was not built in the first place, affecting the drainage's capacity. Therefore, a normalization of the
drainage system is needed to avoid flooding.
