The water resources of Singapore are especially precious given the small amount of densely settled land. Singapore receives an average of 2,400 mm of rainfall annually, well above the global average of 1,050 mm. The constraint is the limited land area to catch and store the rainfall, and the absence of natural aquifers and lakes. [11]
The heaviest rain Singapore recorded was 512.4mm on 2 December 1978, followed by 469mm in December 1969. Severe floods affected areas such as Thomson, Mandai and Olive Road, severely affecting the business in Goodwood Florist as it is a low-lying area.

The map to the right shows a flood map for the City of York, including the floodplain for a 1 in 100-year flood (dark blue), the predicted floodplain for a 1 in 1000 year flood (light blue) and low-lying areas in need of flood defence (purple). The most sustainable way of reducing risk is to prevent further development in flood-prone areas and ...
A Development Guide Plan is then drawn up for each planning area, providing detailed planning guidelines for every plot of land throughout the country. [2] The planning areas were first introduced in the early 1990s after the release of the 1991 Concept Plan. [5]
Improved flood modeling. Flooding, whether from rivers overflowing their banks or in coastal regions, is among the most costly natural disasters. Altimetry data from the SWOT mission will make it possible to measure the 3-dimensional shape of flood waves, track floodwater levels, and improve measurements of local topographic details in floodplains.
Some minor river flooding is possible in the region from a combination of the heavy rain and melting snow on the ground. High Winds. Strong, gusty winds will impact much of the mid-Atlantic and ...
