“Personnel capacity is not able to accommodate such large discharges of water.
In addition to the local rainfall, the water of the shipment from upstream also promotes floods in the Jakarta. Heavy rain in Bogor and the surrounding areas can lead to the overflow of the clogging of the coil and increase the discharge of the water of the Kilivung River, which then flooded the jacascart.
