MOTIVATION• On 23 Oct 2013, continuous rainfall andsubsequent dam release caused Bertam river tooverflow and mud flood to inundate adownstream village, killing 3 people;• Prior to this disaster, fatal landslides hadoccurred in this area in years 1996, 2000, and2008. With the onset of climate change, thesituation in Bertam valley in Cameron Highlands
is looking dire.

2BACKGROUND Cameron Highlands
 Established in 1885 after his
name of Sir William Cameron, aBritish surveyor; one the largest hill resorts inMalaysia,
 referred to as ‘green bowls’,
growing a wide variety ofvegetables, flowers and otherornamental plants.
 also provides many tourist
attractions (tea plantations, tea
factories, rose gardens,
strawberry farms and aging
colonial-style homes).

The green quietude of the CameronHighlands3

BACKGROUND (cont’d) Tech. Facts of Ringlet Reservoir
 man-made lake covering 60 hectares
 upstream of Sultan Abu Bakar Dam
on Bertam River maximum live storage of 4.7MCM
 the storage is connected to the
100MW underground power station
which consists of four small run-ofriver and storage hydro projects andhas five power stations.
 due to land erosion, uncontrolled
development, legal and illegal land
clearing, deforestation, and recklessfarming practices, rubbish, silt andsediment have clogged up the damstorage ; caused the reservoir capacity todecrease to a mere 1.5MCM.

Reducing water related disaster (man-made andnatural); and improving water resourcesmanagement in the context of water nexus andclimate change

PURPOSETo quantify and minimize the impact of climaticand non-climatic factor on sedimentation in Ringlet
Reservoir and water nexus issues within the vicinityof Cameron Highlands
