The Mekong River Commission and the Cambodia National Mekong Committee
are planning to undertake work on the junction of the Tonle Sap, Mekong and and Tonle
Bassac beside Phnom Penh.
The "Chaktomuk junction" as it is known has been moving downstream at a
rate of 10 meters a year.
The MRC said this natural phenomenon, in conjunction with expansion of the city south
of the Cambodiana hotel, had led to heavy erosion of the populated banks of Koh Norea,
and a reduction in the number of sea going ships prepared to travel up river to Phnom
There is also again a deep scour hole in the Tonle Bassac which is once again threatening
to undermine the foundations of the Monivong (Vietnamese) bridge. This happened in
1964 causing the bridge to collapse.
