Background

Sg. Muda, which is located within the boundary of Kedah and Pulau Pinang with a catchment area of 4,210 km2 and 180 km length begin from Muda Dam and flows across district of Baling, Sik and Kuala Muda. Water supply for agricultural, industrial and domestic sector for both Penang and Kedah is the key role of the river.
The catchment often being flooded on the rainy season from April to May and from September to November every year. Many problems raised when flood keep on worsening each year (e.g. riverbank erosion, river pollution and reduction of water resources). The flood event which occurred on October 2003 was the worst compared to previous event in 1988, 1995 and 1998.

Objective

To reduce flooding events that often occur in it's catchment. Flood threats are caused by several factors, which are;

• Steep catchment

• Inadequate size of river to contain flow (Overflow)

• Buildings built on flood prone area

• Developments in the catchment provide flood problems at agricultural areas and towns which are near to the river (e.g. Sik, Baling, Kuala Ketil, Jeniang and Pekula);

• Inadequate size of original barrage to flow excess water during flood events. 

• Heavy and continuous rain in the catchment
