Hydraulic Behavior

Occurrence of extreme hydroclimatological events associated with climatic variability and climate change, along with deficient development of urban drainage systems, have increased the occurrence of floods in cities. This study analyzes the hydraulic behavior of the urban drainage system in the east of Cali, during the occurrence of maximum rainfall events, supported by the Storm Water Management Model. Three simulation climate scenarios were developed: (i) current scenario with a return time of 2 and 10 years, (ii). a climate scenario for the year 2030 and (iii) a climate scenario for the year 2040. The model presented an acceptable grade of calibration, with a Nash-Sutcliffe number greater than 0.5 in simulated events, therefore the results obtained appropriately describe the behavior of surface runoff in the study area, in terms of spatial and temporal resolution. In this way, critical points of the drainage system were identified. This information may be potentially useful in the planning of future hydraulic works, leading to an improvement of the hydraulic behavior of the system, and the protection of life and property of the inhabitants of the city.

This study focuses on the possibility of On-Site Stormwater Detention (OSD) underneath a residential car porch. The space provided in the car porch area can be made good of it by introducing an OSD beneath it to temporary store stormwater from roof during raining in hoping of reducing the surface runoff. The OSD is subjected to 15-minute, 10-year Average Recurrence Interval (ARI) design rainfall. This process in urban hydrology is presented by using Storm Water Management Model (SWMM). Efficiency of the OSD is also investigated by different number of orifice outlets. Modelling efforts report that one orifice outlet is preferable, and it marks approximate 95% discharge reduction at the outfall.

Drainage Channels

Tarakan City experiences problems with standing water during the rainy season, especially in the west Tarakan sub-district which is the center of Tarakan. This puddle not only submerged settlements and offices but also shops and access roads that caused considerable economic losses. An evaluation was carried out by using the Storm Water Management Model (SWMM). SWMM is a rainfall-runoff simulation model used for simulating the quantity and quality of surface runoff from urban areas. Based on the evaluation using SWMM software, the drainage system in Tarakan, especially in Jalan Mulwarman has several inundated channels, namely channels 2, 3, 4, 5, 6, 7, 11, 12, 13, 14. This is influenced by the dimensions of the drainage channel that cannot accommodate existing water runoff and sediment thickness that covers the drainage channels so that the capacity is reduced, if it rains it will cause puddles at several points in Tarakan City. In order to deal with these puddles, it is necessary to change the dimensions of the channel and routinely dredge sediments that cover the drainage channels.

Sewer Overflow

AbstractThe objective of the present study to assess the performance of a suggested sewer line by using pipe jacking system (PJS) in order to enhance the sewage capacity and mitigate sewer flooding of historic pilgrimage city of Karbala, Iraq. The storm water management model (SWMM5) was used for this purpose. The simulation of exiting sewer system reveals that sewer discharge during peak pilgrimage period is more than 200% of the capacity of existing sewer line. Installation of SLL having a diameter of 2.5 m at a depth ranging between 12 and 22 m by PJS can reduce water depth in sewer pipe by 78%. The reduction of water depth at sewer pipe can reduce sewer overflow up to 70%, if the system is installed and managed properly. The methodology proposed in the paper can be applied in any location having similar problem with necessary modifications.

The drainage system of a part of a university campus was tapped using SWMM (Storm Water Management Model). Local drainage discharge capacity was studied under different design storm return period. Results show that flooding and overload at some junctions and in some conduits are doubled with the increase of design rain return period from one year to five year, which may deteriorate the traffic and road base.
