How does Singapore deal with flooding?
Singapore adopts an integrated approach to stormwater management that balances our need for water supply with the need to manage flood risks. With climate change, rainfall events could increase in frequency and intensity.
How are floods managed?
Some of the common techniques used for flood control are the installation of rock beams, rock rip-raps, sand bags, maintenance of normal slopes with vegetation or application of soil cements on steeper slopes and construction or expansion of drainage. Other methods include dykes, dams, retention basins or detention.
Why is Singapore prone to flooding?
Floods are a common occurrence in Singapore usually caused by a combination of heavy rainfall, high tides and drainage problems, especially in low-lying areas. Most floods in Singapore are flash floods that subside within a few hours.
What is the flood line in Singapore?
The Singapore River, which extends into the area from Marina Bay before flowing into the Alexandra Canal, can cause flooding when it overflows. Delta Road, River Valley Road, Delta Avenue, Lower Delta Road, Alexandra Road, Jervois Road, Bishopsgate Road, Indus Road and Zion Road are particularly flood-prone.
What is a flood management plan?
Floodplain management plans provide the framework for coordinating the development of flood works on a whole-of-valley basis. Historically, the management of rural floodplains relied on localised floodplain management plans under Part 8 of the Water Act 1912.
Is Singapore at risk for flooding?
Does Singapore Have Floods? Yes. In Singapore, floods usually affect low lying areas with poor drainage, especially after heavy rains.
Will Singapore be flooded?
Apart from unpredictable weather, there is one other development that could make low-lying Singapore more susceptible to flooding in the decades to come: rising sea levels. As a result of climate change, the sea level around Singapore is also predicted to rise by more than 1m by 2100.
Where are the flood areas in Singapore?
Flood risks were also identified in the central area of Singapore, in Toa Payoh, Bishan and Novena, based on PUB’s interactive map of water-level sensors around the island. Other places that were at risk of flooding included Sengkang, Yio Chu Kang and Choa Chu Kang.
How does the Public Utilities Board manage flooding in Singapore?
To better manage pluvial flooding, the Public Utilities Board (PUB) has developed an extensive 8000 km network of drains, canals and rivers to quickly channel stormwater away from developments. The water is then channeled into reservoirs.
How does PUB manage floods?
PUB takes every flood incident seriously and assesses the cause of any flood. Where necessary, PUB works with other agencies to improve the drainage system or raise road levels to reduce the risk of floods recurring.
Which part of Singapore is higher ground?
Most of Singapore is no more than 15 metres above sea level. The highest point of Singapore is Bukit Timah Hill, with a height from ground of 165 m (538 ft) and made up of igneous rock, granite. Hills and valleys of sedimentary rock dominate the northwest, while the eastern region consists of sandy and flatter land.
