Description
Summary:Bogowonto River is the main river in the Bogowonto watershed which is included in the Serayu Bogowonto River Area. In the dry season, the mouth of the Bogowonto river closes because sediment deposits accumulate at the river mouth, disrupting the river flow to the sea. At high tide, sediment holds the Bogowonto River flow because it impacts the backwater downstream of the Bogowonto river, causing flooding in several locations, especially around Yogyakarta International Airport. The flow capacity of the Bogowonto river is decreasing, causing flooding problems, so this study needs to do an analysis. Backwater analysis at the Bogowonto River estuary simulates the existing jetty in the HEC-RAS program. In contrast, simulated morphology change river was with two jetty scenarios using the DELFT3D program.
