The assessment of drainage performance in the residential area using SWMM

Abstract

Flood is a general issue that can lead to the life and safety of residents. One of the problems is the lack of capacity in the drainage system in a residential area. This paper will analyze the drainage system based on the capacity in one of the residential clusters. The method for the drainage system performance in hydrology analysis was carried out with Log Person, and the return period for rainfall duration is ten years (R10) for hydraulic analysis using drainage system modeling with EPA – SWMM 5.1. The result based on hydrological is the precipitation for flood forecasting is 159.79 mm. It is found that the drainage capacity is filled in downstream of the main drain with a maximum discharge of 2.726 m3/s and secondary drains with a maximum discharge of 0.624 m3/s. Improvements were made to resolve the insufficiency of the existing channels by running two different scenarios: (1) Re-design the dimensions of the main and secondary channels, (2) Implement a detention pond, as well as re-design the dimensions of the secondary channels. Both scenarios could overcome the flood problem. Scenario 2 shows a higher reduction in the flow discharge at the downstream channel compared to scenario 1.

Design of water level detection monitoring system using fusion sensor based on Internet of Things (IoT)

“…This research is included in the field of Control System Applications. Several control system applications have been studied and produced their outputs, such as: vehicle speed control systems based on driver conditions [18,19,20,21], solar light intensity control systems [22,23,24], automation systems at LPG terminals [25, 26,27], as well as a monitoring system for street lighting [28]. The research objective for the next five years is to build and implement an intelligent and integrated control system for monitoring and controlling remotely by utilizing telecommunication systems and the Internet of Things (IoT).…”

Study of Alternative Inundation Management Based on Water Conservation in Sub Drainage System of Parung River, Kediri City

“…The steps in the research work are as follows: a) Conduct a literature review of the literature b) Collection of primary data and secondary data c) Define the area limitation of the catchment sub catchment area (Juliastuti et al, 2023) d) Test the consistency of rainfall data with Rescaled Adjusted Partial Sums (RAPS) analysis (Sri Harto,200 in (Ardiyana et al, 2016) and Double Mass Curve Method (Limantara, 2018) e) Perform trend absence test : Spearman method, stationary test : t-test and F-test method, persistence test : t-test method, outlier test : Grubbs and Beck method (Limantara, 2018) f) Calculation of regional average rainfall thiessen polygon method (Prawati & Dermawan, 2018) g) Frequency analysis Log Pearson Type III, 5th return period (Prawati & Dermawan, 2018) h) Distribution conformity test chi squared test and smirnov-kolmogorov test (Prawati & Dermawan, 2018) i) Create a rain intensity-duration curve using Mononobe formula (Triatmojo, 2008) j) Calculating the discharge of dirty water discharged by residents k) Model rain runoff under existing conditions with SWMM 5.1 and then test statistics using Nash-Sutcliffe Efficiency (NSE), (Mengistu et al, 2022) correlation coefficients to measure the accuracy of the model's forecasts. (Suhartanto, 2016) The NSE value and the resulting correlation coefficient when approaching 1 (one) indicate that the variation in values produced by a forecast model is close to the variation in the observed value.…”

Effect of near-surface heterogeneities on the pore-water pressure distribution and slope stability

“…The reduction in soil shear strength resulting from elevated pore water pressure and reduced matrix suction can result in slope failure. For example, rainfall-induced slope instability has been studied by [1,2,3,4,5]. The studies concluded that the stability of a slope is influenced mainly by the geometry of the slope, the soil characteristics, and the rainfall duration and intensity.…”
