Abstract

Sungai Brantas bercabang dua untuk menuju muara yaitu Sungai Kali Mas arah Surabaya dan Sungai Porong, Kali Mas mempunyai hilir air laut, air laut pasang langsung berdampak backwater terhadap aliran Kali Mas yang mengakibatkan sebagian penampang meluber dan saluran sekunder Kali Mas tidak bisa mengalir secara gravitasi. Data yang dibutuhkan adalah data curah hujan sekitar kali mas 12 tahun terakhir, data pasang surut air laut 2 tahun terakhir, penampang Sungai Kali Mas dari hulu ke hilir, penampang saluran sekunder Kali Mas. Curah hujan menggunakan metode Gumbel hasilnya 121.73 mm/jam, debit banjir rencana menggunakan metode rasional menghasilkan 17.49 m3/det, hidrograf banjir menggunakan metode Nakayasu, dan dari didapat alternatif solusi mengendalikan aliran dengan pintu air dan pompa air, dimensi 4 m x 5 m sebanyak 5 pintu dan pompa air menggunakan 3 m3/det sebanyak 8 pompa dan 1 m3/det sebanyak 1 pompa. ================================================================================ Brantas Riverhave 2 channels, one channel is Kali Mas River and the other is Porong River, the downstream Kali Mas River is a Sea, direct contact with the tide and the due is a backwater, that the effects make a cross of Kali Mas is overflow and the secondary channels can’t flow by gravity. The data needed are 12 last years the rainfalls, 2 last years the tides, the primer cross of Kali Mas river from upstrem to downstream and the secondary cross of Kali Mas rivers. The method to plan the rainfall through Gumbel method and the result is 121.73 mm/hour ,rasional method flood discharge plan to produce 17.49 m3/sec, and the method of flood hydrograph uses Nakayasu Method, from result tidal the solution to controlling the flow Kali Mas is used pumps and gates, the dimension of gates are 3 m x 4 m by 5 doors, the pumps uses 3 m3/sec by 8 pumps and 1 m3/sec by 1 pump.
