Slump on hill slope in Singapore (Before and after soil management)


Photograph of a slump near the top of a hill slope along Bartley Road, Singapore, on 12 November 2011.

The slope has been covered with a large sheet to prevent further soil erosion since then. The large sheet also helps to prevent a possible landslide, especially during heavy rains.

The photograph below of the covered slope (shown on the left) was taken on 17 June 2012.


Update (December 2012 - about one year after the first photograph was taken)

The hill slope has been restored as new grass has been replanted to hold the soil firmly. The photograph below shows the result of good soil management.

Nature walk around MacRitchie Reservoir

I went for a three-hour walk this afternoon, starting from MacRitchie Reservoir Park and ending at the edge of the rainforest along Lornie Road.

Along the way, I went to the canopy treetop walkway - I managed to reach there half an hour before the gate closed at 5 p.m.

Hot spring in Sembawang, Singapore

This afternoon, I went to find a hot spring in the northern part of Singapore and managed to find it about two hours of walking. I knew about it some years ago from the newspaper but didn't think of visiting it since I thought it's just a small spring located in a remote part of the rainforest.

Recently, while reviewing an article for my magazine project about green or renewable energy, I came across more information about the hot spring. I learnt that some university academics wrote about doing a feasibility study of harnessing the hot spring for geothermal energy in future. So I decided to find out where this mysterious hot spring is since my idea of hot springs is that they are usually found in some remote volcanic regions, and there aren't any volcanoes on the small island of Singapore. The hot spring proves elusive because it is actually located nearer a newly built residential area than I thought, and the entrance to the hot spring isn't very noticeable.
