Evaluation of an Urban Drainage Channel System on Tuamang Road, Medan

Abstract

The population that continues to grow every time affects the total wastewater that is accommodated and channeled by drainage. This study aims to evaluate the existing condition of drainage dimensions on Tuamang Road, Medan. To determine whether the drainage can still channel the design wastewater discharge for the next 10, 20, and 30-year return periods or if it requires re-planning. The descriptive-evaluative method is used to evaluate drainage with stages starting from collecting data on population, annual rainfall, and measuring the dimensions of drainage channels; hydrological analysis, population projections for 10, 20, and 30-year; and evaluation of drainage channels. The research location is on Tuamang Road with a length of 1,200 m from Domestic House No. 130 to No. 101. The drainage system on Tuamang Road can still channel rainwater runoff and household waste for up to 10-year, based on analysis. 20 and 30-year, the dimensions must be enlarged to 1.0 m (bottom width) and 0.7 m (wet height of the channel). Cleaning sediment at the channel bottom must continue regularly to ensure the drainage system is working properly

Implementation of Building Information Modeling (BIM) on Drainage Channel Design in UB Forest Sumberwangi Area

“…A design flood discharge is a discharge whose magnitude is equaled or exceeded once in a certain return period, for example, Q10, meaning that a discharge will statically occur once in 10 years, and the probability of it occurring every year is 1/10 [13]. In this study, the method for determining the amount of drainage runoff discharge is the Rational Method (rational method) with Equation (1) as follows [18], [19].…”

Evaluation of an Urban Drainage System in a Big City

“…It has a population of 2.4 million. Transmigration and urbanization have caused the city to expand quickly in the previous ten years (Pasaribu et al, 2022). According to data from 2010, Medan City's population expanded by almost 340 thousand individuals, or roughly 15-20 thousand more people each year (BPS, 2022).…”
