DSDABM Surabaya Overcome Rob Flood With Channel Normalization

SURABAYA - The Surabaya City Water Resources and Highways Service (DSDABM) is trying to overcome the tidal flood in the City of Heroes by normalizing and cleaning primary water channels. inundation from tidal waters that began to occur on Monday 13 June and potentially until 17 June 2022. he said. Lilik stated that the channel at the sea estuary was a priority because the pump house had to be closed due to high tides. "That's why we are optimizing the dredging at the Wonorejo Avor and at the Wonorejo 1 and 2 pump channels," he said. According to him, the position of the puddle of rainwater on Monday, June 13 occurred in the casement of the Kebon Agung and Wonorejo Avor canals, but not all of them. This means, he said, inundation only occurs in the middle and downstream areas. "The Kebon Agung pump is optimal. Only Wisma Penjaringan is subject to high tides, so there may be inundation in the area," he said, quoted by Antara. intensely conducting searches on Avor Wonorejo to review the condition of the channel geometry, including intensely conducting normalization and cleaning of channels to prevent inundation.

"We are now tracing the Wonorejo vortex, starting from Kalirungkut until the sea water is seen as the geometry of the channel is shallow. So, the concentration is now normalizing," he said. Forecaster of BMKG Maritime Tanjung Perak Surabaya Fajar Setiawan previously said, the peak of tidal flooding will occur on June 15, where The height of the tidal flood is at level 160 of the average sea level. "This condition will cause inundation in coastal areas to reach 30 to 40 cm," said Fajar. What's more, this condition can be exacerbated by the La Nina phenomenon. "If it happens simultaneously, there is rain, the tide continues to occur, then automatically the water in the river will be even more difficult to flow into the sea," he said.
