Abstract

Tugas akhir terapan ini bertujuan untuk mengendalikan banjir di afvoer Pucang kabupaten Sidoarjo. Untuk mengendalikan banjir di saluran tersebut perlu mengurangi debit air di afvoer Pucang dan mengalirkanya ke afvoer Kemambang. Normalisasi sungai Pucang telah dilakukan namun langkah tersebut kurang mampu untuk mengatasi banjir di afvoer Pucang. Untuk menghitung debit banjir yang terjadi digunakan metode rasional dan metode nakayasu sebagai pembanding. Dari debit banjir tersebut bisa diketahui berapa besar debit yang akan dialirkan ke saluran sudetan serta dimensi sudetan. Perhitungan kapasitas alir diperlukan untuk mengetahui kemampuan saluran tersebut untuk mengalirkan sejumlah debit air. Pengoperasian pintu air diatur dengan menganalisa elevasi muka air dan debit yang akan dialirkan. Dari hasil analisa dan perhitungan yang ada didapatkan besar debit yang akan dialirkan melewati sudetan sebesar 10,20 m3/dt. Dimensi saluran sudetan direncanakan memiliki lebar dasar 3 m dan tinggi saluran 3 m. Pintu air Sumput dibuka maksimal setinggi 1,4 m dan pintu air sudetan dibuka setinggi 1m. =========================================================================================================== This Applied final project aims to control flood in Sidoarjo district Pucang afvoer. For controlling this flood in that channel need to reduce the flow rate in afvoer Pucang and flowed that to afvoer Kemambang. Pucang river normalization has been done, but these measures are less able to cope with flooding in afvoer Pucang. Calculating the flood discharge that occurs use rational methods and Nakayasu methods as a comparison. From the flood discharge can be known how great the discharge to be supplied to the diversion channel as well as the dimensions of short-cut river. The flow capacity calculate necessary is determining the ability of the channel to drain some water discharge. Operation floodgates governed by analyzing the water level and discharge that will be streamed. Result from the analysing and calculationing there will be obtained a large discharge flowed through the diversion of 10,20 m3/sec. The dimensions of the planned diversion channel has a basic width of 3 m and a height of 3 m duct. Sumput floodgates opened up as high as 1.4 m and the floodgates of short-cut opened up as high as 1 m.
