Climate Data Information

Tonle Sap wetland and the influence of climate change Model of Tonle Sap Tonle Sap is the largest lake in South-East Asia and is a wetland of international importance and is recognised by the Ramsar convention. Like most wetlands its area varies significantly through the year, from 2000 km 2 at its lowest to ten times that figure at its largest.   The bed of lake is close to sea level and its maximum level is normally only 10 m above sea level. The channel from the lake to the Mekong can flow in either direction. When levels in the lake are higher than those in the Mekong water flows out of the lake toward the Mekong (generally from October to April) and for the rest of the year it flows in the opposite direction.  The following map shows three significant locations for level and/or flow measurement. Levels in the lake are recorded at Kampong Loung.   Figure 1 - Important measuring sites related to the model of Tonle Sap    Levels ...
