LOCATION PLAN Pantai Kerachut

This is the location plan of Pantai Kerachut in Penang National Park, Malaysia. This area is found at the north-

western tip of Penang island. It is popular for its harmonious serenity of nature and man. A very special feature of

this site is the ‘’Meromictic Lake’’ which is a seasonal lake. The lake is surrounded by a variety of rich vegetation.

The lake’s mouth is connected to the Malacca Strait.

SITE PLAN

This area denotes our intended site area of 100m x 200m, ensuring the bridge entrance is included as well as the

mouth of the lake, where a special phenomenon takes place. That of allowing sea water into the lake but

preventing it from backwashing into the sea, creating two layers of water ; fresh water and sea water in the lake,

hence the name, Meromictic Lake. Our site also allows generous amount of flat gentle land.

areas of gentle flat land.

SECTIONS

Due to the complex terrain surrounding our site, we realised it would be ideal for us to have general sections of the

area instead of simply limiting it to within our site, to indicate the gradient of the slopes as well as their heights above

sea level.

WIND When the wind pressure flows through the enclosed area of

the trees and vegetations, being smaller in diameter, the

restriction causes a higher pressure at the narrow end. This

difference in pressure causes the wind flow to accelerate

towards the low pressure narrow section, creating a higher

constant speed.

a lake that can adapt to two types of water:

where it mainly receive water from five different

Due to the presence of different densities in

these two water, the lake is seperated into two

layer.

Besides, the lake also consist of two different

temperature.The stream water on the lower
