Abstract
Grogol Subdistrict is a business, trade, and service area experiencing economic growth and development; however, flooding remains a challenge that must be addressed because it is classified as a flood-prone area. Dukuh Menggungan, Telukan Village, is one of the areas affected by flooding. This study aims to analyze the drainage system in Dukuh Menggungan. The research methods used included hydrological analysis using the Pearson Log-Distribution III and the Mononobe Method, followed by hydraulic analysis using the Rational Method. The calculated discharge rates for Channel A were 0.634 m³/second, for Channel B 0.907 m³/second, and for Channel C 3.384 m³/second. It was therefore concluded that Channels A and B do not meet their capacity requirements, while Channel C does meet its capacity. The recommended alternative solution is to plan 45 infiltration wells around Channel A, with a captured flow rate of 1.471 m³/s greater than the uncaptured flow rate of Channel A, which is 1.182 m³/s as well as 55 infiltration wells around Channel B with a captured flow rate of 1.798 m³/s, which is greater than the flow rate not accommodated by Channel B, which is 1.710 m³/s. Keywords: flooding, drainage system, design flow, flood discharge, infiltration well Kecamatan Grogol merupakan kawasan bisnis perdagangan dan jasa yang mengalami pertumbuhan ekonomi dan pembangunan, namun permasalahan banjir menjadi tantangan yang harus dihadapi karena termasuk wilayah rawan banjir. Dukuh Menggungan, Desa Telukan adalah salah satunya yang terdampak banjir. Penelitian ini bertujuan untuk menganalisis sistem drainase Dukuh Menggungan. Metode penelitian yang digunakan analisis hidrologi Distribusi Log Pearson III dan Metode Mononobe dilanjutkan analisis hidrolika dengan Metode Rasional. Hasil perhitungan debit saluran pada Saluran A sebesar 0,634 m3 /detik, Saluran B sebesar 0,907 m3 /detik dan Saluran C sebesar 3,384 m3 /detik. Maka disimpulkan bahwa Saluran A dan Saluran B tidak memenuhi kapasitas dan Saluran C memenuhi kapasitas. Solusi alternatif yang disarankan adalah perencanaan sumur resapan berjumlah 45 titik di sekitar Saluran A dengan debit air yang tertampung sebesar 1,471 m3 /detik lebih besar dari debit air yang tidak tertampung oleh Saluran A sebesar 1,182 m3 /detik, serta 55 titik di sekitar Saluran B dengan debit air yang tertampung sebesar 1,798 m3 /detik lebih besar dari debit air yang tidak tertampung oleh Saluran B sebesar 1,710 m3 /detik. Kata Kunci : banjir, sistem drainase, debit rencana, debit banjir, sumur resapan
