Abstract

Mati River is one of the rivers in Bali that has experienced very rapid changes related to land use in its watershed area. This change was triggered by the very rapid development of Denpasar City. This change has triggered a decrease in water catchment areas, increasing surface runoff and potentially causing flooding and waterlogging in several areas. Other conditions that support the occurrence of inundation and flooding are the narrow and winding condition of the Mati River body and the relatively flat conditions around the river, making it difficult to drain water to the estuary area. Several flood management efforts have been attempted, starting from normalizing the channel by making the river cross-section wider and with precast concrete, changing the fixed dam into a movable dam and making a pneumatic crest gate type Mati movable dam at the estuary. The construction of a pneumatic crest gate type movable dam is one of the innovations because in addition to its function to increase the river’s capacity to accommodate raw water in the future. The pneumatic crest gate was built in 2020 and until now there has been no study conducted regarding its effect on reducing flood discharge. The research method uses a quantitative method and the research results are in the form of a percentage value of the effect of reducing the flood water level in the Mati River during floods.
