Periods of drought can affect the reliability of Singapore’s water supply, while sudden episodes of intense rainfall could overwhelm our drainage system and lead to flash floods.
Why is Singapore vulnerable to flash floods?
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.
Is Singapore vulnerable to climate change?
As a low-lying island city state, Singapore is particularly vulnerable to the impacts of climate change.
How does Singapore deal with floods?
DRAINAGE AND FLOOD PROTECTION
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.
What is being done in Singapore to manage the rising sea levels?
Singapore’s plans to defend against rising seas include building sea walls, polders, and new islands made from reclaimed land. New buildings are to be built four metres above mean sea level, and critical infrastructure at least another metre higher.
What causes heavy rain in Singapore?
This is partly due to the intense moisture-laden winds blowing from the tropical Indian Ocean and Java Sea toward Southeast Asia. As per the Meteorological Service Singapore (MSS) report, June was the wettest, and September the second wettest in the last 10 years.
What is meant by flash flood?
Flooding that begins within 6 hours, and often within 3 hours, of the heavy rainfall (or other cause). Flash Floods can be caused by a number of things, but is most often due to extremely heavy rainfall from thunderstorms. … Flash Flooding occurs so quickly that people are caught off-guard.
Will Singapore go underwater?
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.
What are 5 effects of climate change?
What are the effects of climate change and global warming?
- rising maximum temperatures.
- rising minimum temperatures.
- rising sea levels.
- higher ocean temperatures.
- an increase in heavy precipitation (heavy rain and hail)
- shrinking glaciers.
- thawing permafrost.
How does Singapore handle climate change?
Singapore’s Pledge to Reduce Emissions
On 31 March 2020, Singapore submitted its enhanced Nationally Determined Contribution (NDC) and Long-Term Low-Emissions Development Strategy (LEDS) document to the UNFCCC. Singapore’s enhanced NDC now states an absolute emissions target to peak emissions at 65 MtCO2e around 2030.
Can we prevent floods in Singapore?
To better protect against floods, buildings can add structural measures such as humps and flood barriers to protect their basement levels from floodwaters. They can also link the water-level sensors in the basement carparks to their alarm systems in order to warn their users of flooding.
