Abstract

ABSTRACTSoil types have different infiltration rates and vary depending on the characteristics of the soil, how the infiltration relationship occurs with dry water content and saturated water content, infiltration relationship with the soil after being compacted and before compacted and how the infiltration rate of the two types of relationship and how infiltration water that happened. Soil tests are carried out in the laboratory, soil water content before and after the soil has been solidified, changes in the time of infiltration capacity with the Horton equation, rain hydrograph for overall infiltration analysis, including cumulative infiltration and runoff rates.Soils experience porosity filling not as great as in normal soil conditions, normal soil conditions changes in water content reaches 5.22 mm/hour while in soil conditions that experience changes in water content compaction at 30 minutes by 0.14 mm/hour and experiences a constant rate in the 40th minute at a rate of 0.20 mm/hour, so there is a difference in water content of 5.08 mm/hour between normal soil and soil after solidification, due to compacting it causes runoff of 8.92 mm/hour, normal soil with runoff of 3.78 mm/hour.Keyword :  Infiltration, soil physical properties, runoff.

Abstract

The rain that fell in the city of Cirebon, especially the drainage on Jalan Pemuda, could not accommodate and drain the water so that it could create puddles on the roads and surrounding areas. Hourly rain intensity, planned flow rate and channel cross-sectional dimensions are the first steps for flood prevention. Hydrological analysis is used to calculate the discharge capacity of the drainage plan. The results were then analyzed the dimensions of the channel, the drainage ability to accommodate the falling rainwater where Qs is bigger than Qp. the channel discharge has not been able to accommodate the Q plan in the channel so that there will be a runoff of 17.759%. So to anticipate runoff, it is necessary to have a channel improvement plan of 33.477%. In addition to channel improvement solutions, arrange and define the boundaries of water storage areas by measuring and mapping boundaries and issuing regulations that prohibit or limit the construction of buildings that can reduce the ability of areas to store and absorb rainwater by referring to the basic building coefficient (KDB) permitted as stated in the RT/RW.

Abstract

The urban area of Cirebon City, Indonesia, with its tropical climate, in the Sunyaragi sub-district, is increasingly affected by surface runoff and flooding due to limited drainage capacity and extensive impervious surfaces. This study evaluates the effectiveness of a modular infiltration box system in reducing urban stormwater runoff. Hydrological data from Harjamukti, Kamun, and Kertajati stations from 2014 to 2023 were analyzed using a Log Pearson Type III distribution to determine rainfall intensity for return periods of 2, 5, and 10 years. Field Experiment and Laboratory Analysis Methods: Soil infiltration characteristics were tested using a double ring infiltrometer and modeled with the Horton infiltration equation. Infiltration boxes measuring 1.00×0.50×0.45m were installed on the road median in two configurations, single layer (22 units) and double layer (44 units). The results showed that the single-layer system reduced runoff by 43.06% for a 5-year return period (15-minute duration), while the double-layer system achieved a reduction of up to 86.60% for a 2-year return period (20-minute duration). Further improvements were observed when combined with infiltration wells, achieving runoff reductions of over 95%. These findings demonstrate that modular infiltration boxes are an effective and scalable alternative solution for decentralized urban stormwater management, contributing to flood mitigation and sustainable drainage planning.

Abstract

Problems that often arise in the city of Cirebon are flooding caused by rain, land changes not supported by adequate infrastructure, narrowing of drainage channels and sedimentation of channels. This is the location where flooding often occurs in the Pemuda Street area and its surroundings. Therefore, it is necessary to carry out research on surface flow analysis as an effort to handle floods with the aim of inundation management strategies to reduce excessive rainwater runoff in drainage areas and channels. The research methods used were problem identification, literature study, data collection, analysis and design planning. The results can show that inundation is handled in two ways, first by changing the dimensions of the channel at the initial height H to 0.45m, it still experiences inundation, this is due to the difference in elevation which causes inundation in the channel. There was a change in the flood inundation area to 23,127 ha from the original 58,958 ha, meaning that the flood free area increased from 9,388 ha to 35,831 ha. The second way is by making 378 infiltration wells spread across 34 channels that experience flooding. With these infiltration wells, the flooding can be reduced to a minimum from an area of ​​23,127 ha to 0.040 ha. The success rate for flood management efforts reached 99.908%, with failure being 0.092%. Of the area of ​​68,346 ha, the flood-free area reached 68,306 ha and the remaining inundated area was 0.040 ha..

Abstract

Rainy season flooding: Ujung Jaya Regency experiences flooding almost every year, this annual flood phenomenon causes material losses. The research aims to analyze the capacity of the Cipelang River which is located in Sumedang Regency. The Cipelang River is part of the Cimanuk Watershed (DAS) with an area of ​​around 130.70 km², which has several tributaries such as Ciandana, Cicacaban, and Cipanassaat. The methods used in this research include collecting hydrological data, topographic analysis, and evaluating land use around the river. Rainfall and river flow data were taken from the nearest meteorological station to determine water storage potential. Results of analysis of existing river storage capacity and flood discharge. The maximum capacity of the Cipelang river is 409,002 m3/s. Nakayasu HSS method planned discharge using river watershed discharge occurs in the 100 year anniversary period. However, time periods of 2,5,10,25,50 years are considered safe. The results of comparing the planned discharge of the Hasper method with the discharge of the river catchment did not occur. So the most suitable method to use is the hasper method, land use which is dominated by irrigated rice fields and gardens also contributes to water management in this watershed. It is hoped that this research can provide recommendations for better water resource management and flood risk mitigation in the area. These findings are important to support sustainable infrastructure development and maintain ecosystem balance in the Sumedang Regency area.  Keywords: Rain , River, Discharge, Capacity, Flood
