Abstract
Sungai Tenggang merupakan salah satu sungai di Semarang yang sering meluap. Diduga penyebab genangan akibat banjir hujan lokal dan banjir rob. Hal ini perlu dilakukan kajian untuk menanggulangi permasalahan tersebut. Untuk menanggulanginya perlu diperhitungkan beberapa aspek yaitu aspek hidrologi, aspek hidrolika dan alternatif pemecahan masalah.Perhitungan debit rencana menggunakan metode nakayasu dengan debit Q25, dan dihasilkan debit rencana adalah 100 m3/detik. Perhitungan kapasitas eksisting sungai Tenggang menggunakan rumus Manningdan dihasilkan kapasitas eksisting adalah 84 m3/detik.Berdasarkan hasil perhitungan, tidak terjadi banjir rob. Untuk mengatasi banjir hujan di bagian hilir, direncanakan sudetan dengan debit 16 m3/detik, kolam retensi dengan volume 23.669 m dan 1 pompa dengan debit 3,55 m3/detik.

Tenggang River is one of the rivers located in Semarang that is often overflowing. The caused of the inundation are flood caused by rain and tidal flood. This needs a study to overcome the problem. To overcome it, some aspect such as hydrology, hydraulics, and alternative solutions should be calculated.Debit calculation plan using Nakayasu method with Q25 debit, and the result of the calculation is 100 m3/s. The calculation result of existing capacity of Tenggang River using the formula of Manning is 84 m3/s.Based on the calculation result, no tidal flood occurred. To overcome the flood caused by rain in downstream, shortcut is planned with 16 m3/s as debit, retention pond with 23.669 m as volume, and 1 pump with 3,55 m3/s as debit.
