Abstract: Drainase merupakan suatu sistem untuk menyalurkan air hujan. Sistem ini mempunyai peranan yang sangat penting dalam menciptakan lingkungan yang sehat, apalagi di daerah berpendudukan padat seperti perkotaan. Evaluasi saluran drainase diperlukan untuk mengetahui kapasitas penampang dengan menghitung debit banjir rencana menggunakan metode Rasional. Analisa debit banjir rencana dilakukan dengan menghitung curah hujan rencana dengan metode distribusi yang dipilih yaitu Log Pearson Tipe III. Dari hasil analisa debit banjir rancangan periode ulang di dapat Q2 sebesar 0,772 m3/dt, Q5 sebesar 0,9706 m3/dt dan Q10 sebesar 1,1051 m3/dt. Evaluasi saluran drainase pada kawasan kampus 1 UMA Kecamatan Percut Sei Tuan dilakukan dengan perhitungan hidrolika sederhana. Dari perhitungan kapasitas saluran eksisting di dapat Qkanan sebesar 0,4035 m3/dt dan Qkiri sebesar 0,3670 m3/dt. Hasil evaluasi menunjukkan saluran drainase pada kawasan Kampus 1 UMA Kecamatan Percut Sei Tuan tidak dapat menampung debit banjir rancangan Q2, Q5 dan Q10. Maka dilakukan evaluasi untuk saluran kiri dan kanan, sehingga di dapat debit saluran rancangan Qkiri sebesar 1,0274 m3/dt dan Qkanan sebesar 1,0295 m3/dt. Dimana Qkanan > Qrancangan 2 dan 5 tahun. Dan untuk Qkiri > Qrancangan 2 tahun. Irrigation is very important for social life especially fermer in rice fields to fine and gives the water on they farm. Irrigation regions is a lend area need the water in fill by irrigation system. Usually a paddy fields that require a lot of water for the production of rice. As for component for the availability of water that is debit mainstay which on counting by using the Weibull method. For the irrigation water demand component includes the need for water for land preparation and an alternative cropping pattern. While for the potential area of irrigation covers the major discharge and large water discharge needs. While the main discharge is 67,26 m3/dt. And the maximum water demand is 2,12 lt/det/ha in alternative 11. And potential area is 31726,4 ha, while the area used at present is 25280 ha. So from the calculation and evaluation proved the availability of water that is still sufficient for water needs in the area of Campus UMA irrigation is 6446,4 ha.
