Abstract
Sistem Drainase Maria merupakan salah satu sistem drainase yang ada di Nganjuk. Banjir disebabkan sistem drainase yang tidak maksimal menampung intensitas hujan tinggi, sedimentasi yang menumpuk, bangunan liar yang berdiri di aliran sistem drainase, serta kurangnya kesadaran masyarkat setempat untuk tidak membuang sampah ke sistem drainase. Tujuan dari penelitian ini adalah mencari kapasitas saluran drainase menggunakan analisis perhitungan debit banjir rancangan dengan debit banjir dan debit kotor untuk memperoleh perbandingan antara debit air dengan kapasitas drainase. Untuk metode pengelolaan data akan menggunakan metode Polygon Thiessen untuk menemukan curah hujan rerata daerah. Data hidrologi didapat dari stasiun pencatat curah hujan selama 15 tahun terakhir. Kemudian Analisa metode rasional untuk menghitung debit banjir rencana kala ulang 10 tahun yaitu Q10 = 6,52 m³/detik. Dari hasil Analisa didapatkan 26 saluran tidak mampu menampung debit banjir rancangan. Maka dari itu solusi untuk mengatasi masalah ini, Saluran direncanakan Kembali dengan dimensi lebar berkisar 0,4 meter hingga 1,1 meter dan tinggi saluran dari 0,5 meter hingga 1,5 meter

Maria drainage system is one of drainage system that existed in Nganjuk. Flood caused by drainage that can’t store high intensity rain, sedimentation piling up, wild building stood on drainage system, and low awareness of local community to not littering at drainage system. The purpose of this study was to find the drainage system capacity using analysis of the calculation of the design flood discharge with dirty water discharge to get a comparison between the water discharge and the capacity of drainage system. For the data management method will use the Polygon Thiessen method to find region average rainfall. Hydrology data were obtained from rain station from last 15 years. Then, rational method analysis to count flood discharge plan at 10-year return period (Q10) is 6,52 m³/s. From analysis, we found out there are 26 channels that cannot contain flood discharge. Therefore, to solve this problem drainage channel need to redesign its dimension with the width varies from 0,4 meter up to 1,1 meter and the height varies from 0,5 meter up to 1,5 meter.
