Assessing Climate Change Impacts on River Flows in the Tonle Sap Lake Basin, Cambodia

This research paper describes a study using a calibrated SWAT model to simulate baseline river flows and assess future climate change impacts across 11 sub-basins of the Tonle Sap Lake Basin in Cambodia.

• The Tonle Sap Lake's tributaries are critical for maintaining dry-season lake levels and contribute 25–30% of the annual flow, with an additional 12.5% coming from precipitation, yet these sub-basins have been poorly monitored and studied compared to the Mekong River mainstream.
• Cambodia is highly vulnerable to climate change because approximately 80% of its population relies on the agriculture sector for their livelihoods, making the country susceptible to food shortages and crop failures caused by increased flooding and severe water scarcity.
• Water resources in the Tonle Sap region have been pressured over recent decades by several factors, including hydropower demand, agricultural expansion, deforestation, urbanization, and rapid population growth.
