E. Rehabilitation of Major River and Straits of Johor<br />
Major rehabilitation of rivers such as Sungai Skudai and Sungai Tebrau<br />
should be carried out to prevent erosion and siltation caused by the<br />
construction of major embankment work, to improve water quality.<br />
This work should also be carried out along the coastal areas of SJER<br />
stretching from east to west.<br />
The main reason of flooding in this area is due to insufficient capacity to<br />
receive the additional discharge. Some of the rivers meander and as a<br />
result, siltation easily occurs at the river mouth, causing flood. The situation<br />
become worse when there is heavy rain and high spring tide. The rapid<br />
pace of development within the district of Johor Bahru also contributes<br />
to the flooding at the river basin area, as insufficient drainage causes<br />
blockages and flash flood.<br />
Illegal Squatters Within The Reserve<br />
of Sungai Skudai<br />
Example of an Embankment Work<br />
The presence of illegal squatters within the river reserve areas, especially<br />
at Sungai Skudai and Sungai Tebrau, can also contribute to flooding, as it<br />
impedes maintenance work by the drainage department. In addition this<br />
results in unpleasant views along the rivers and poor water quality due to<br />
the disposal of domestic waste by the illegal squatters.<br />

C. New Target of Projection and Commitment<br />
The rate of land conversion in SJER is quite high. As sites cleared for<br />
development, this may result in an increase in surface run off and peak<br />
flows that can easily cause flooding; especially at the river estuary. Many<br />
rivers have been narrowed due to land development and subsequent<br />
