This study addresses the engineering parameters required to design efficient drainage systems for access roads and parking facilities. By applying the Rational Method for peak flow estimation and Manning’s Equation for open-channel flow sizing, we establish a protocol to manage hydrological loads effectively. The research underscores the importance of proper slope gradients, material permeability, and maintenance schedules to prevent pavement deterioration and water-induced structural damage. This guide serves as a technical benchmark for civil engineers and contractors. 1. Introduction The failure of pavement and parking surfaces is frequently attributed to poor water management rather than structural load deficiencies. In tropical climates, where precipitation intensities are extreme, the drainage system must be designed to accommodate high-volume runoff within short temporal windows. Traditional approaches often underestimate the impact of urbanization on catchment areas, leading to localized flooding and foundation erosion. 2. Hydrological Analysis To determine the capacity of the drainage system, one must first calculate the peak discharge ($Q$) using the Rational Method: $$Q = \frac{C \cdot I \cdot A}{360}$$ Where: $Q$ = Peak runoff rate ($m^3/s$) $C$ = Runoff coefficient (dimensionless, ranging from 0.70 for asphalt to 0.95 for concrete) $I$ = Rainfall intensity ($mm/hr$) $A$ = Catchment area ($ha$) 3. Hydraulic Design Methodology Once the peak flow is established, the channel or pipe dimensions must be sized to prevent overflow. Manning’s Equation is utilized for open-channel velocity ($V$): $$V = \frac{1}{n} \cdot R^{2/3} \cdot S^{1/2}$$ Where: $V$ = Velocity of flow ($m/s$) $n$ = Manning’s roughness coefficient $R$ = Hydraulic radius (Area / Wetted Perimeter) $S$ = Channel slope ($m/m$) To ensure self-cleaning velocity and prevent sedimentation, the channel slope ($S$) should generally maintain a minimum velocity of $0.6 \text{ m/s}$. 4. Implementation and Maintenance For access roads and parking lots, cross-slope design is critical. A minimum cross-slope of 2% is recommended to divert water effectively toward the drainage inlets. Regular maintenance protocols, including the removal of debris from catch basins, are mandatory to maintain the design capacity throughout the monsoon season. 5.

Studi ini membahas parameter rekayasa yang diperlukan untuk merancang sistem drainase yang efisien untuk jalan akses dan fasilitas parkir. Dengan menerapkan Metode Rasional untuk estimasi aliran puncak dan Persamaan Manning untuk ukuran aliran saluran terbuka, kami menetapkan protokol untuk mengelola beban hidrologis secara efektif. Penelitian ini menggarisbawahi pentingnya gradien kemiringan yang tepat, permeabilitas material, dan jadwal pemeliharaan untuk mencegah kerusakan aspal dan kerusakan struktural akibat air. Panduan ini berfungsi sebagai tolok ukur teknis bagi insinyur sipil dan kontraktor. 1. Pendahuluan Kegagalan permukaan jalan dan area parkir sering dikaitkan dengan manajemen air yang buruk, bukan karena kekurangan beban struktural. Dalam iklim tropis, di mana intensitas curah hujan ekstrem, sistem drainase harus dirancang untuk mengakomodasi limpasan volume tinggi dalam waktu singkat. Pendekatan tradisional sering kali meremehkan dampak urbanisasi pada daerah tangkapan air, yang menyebabkan banjir lokal dan erosi fondasi. 2. Analisis Hidrologis Untuk menentukan kapasitas sistem drainase, seseorang harus terlebih dahulu menghitung debit puncak ($Q$) menggunakan Metode Rasional: $$Q = \frac{C \cdot I \cdot A}{360}$$ Di mana: $Q$ = Laju limpasan puncak ($m^3/s$) $C$ = Koefisien limpasan (tanpa dimensi, berkisar dari 0,70 untuk aspal hingga 0,95 untuk beton) $I$ = Intensitas hujan ($mm/jam$) $A$ = Luas daerah tangkapan ($ha$) 3. Metodologi Desain Hidrolik Setelah aliran puncak ditentukan, dimensi saluran atau pipa harus disesuaikan untuk mencegah luapan. Persamaan Manning digunakan untuk kecepatan aliran saluran terbuka ($V$): $$V = \frac{1}{n} \cdot R^{2/3} \cdot S^{1/2}$$ Di mana: $V$ = Kecepatan aliran ($m/s$) $n$ = Koefisien kekasaran Manning $R$ = Jari-jari hidrolik (Luas / Keliling Basah) $S$ = Kemiringan saluran ($m/m$) Untuk memastikan kecepatan pembersihan diri ( self-cleaning velocity ) dan mencegah sedimentasi, kemiringan saluran ($S$) umumnya harus mempertahankan kecepatan minimum $0,6 \text{ m/s}$. 4. Implementasi dan Pemeliharaan Untuk jalan akses dan area parkir, desain kemiringan melintang ( cross-slope ) sangat krusial. Kemiringan melintang minimum sebesar 2% direkomendasikan untuk mengalihkan air secara efektif menuju saluran drainase. Protokol pemeliharaan rutin, termasuk pembersihan puing dari bak penampung ( catch basin ), bersifat wajib untuk menjaga kapasitas desain sepanjang musim hujan. 5.
