Tonle Sap River Flow Dynamics

The Tonle Sap River in Cambodia reverses its flow direction annually, influenced by the rainy and dry seasons. During the rainy season, the river expands and flows into the Tonle Sap Lake, while in the dry season, the lake overflows back into the river, reversing its course. This natural phenomenon supports local fishing and agriculture. However, climate change is altering these patterns, potentially impacting food supplies. Research models aim to predict future changes, helping communities adjust their agricultural practices.

What natural phenomenon causes the Tonle Sap River to change its flow direction annually?

• Earthquakes

• Rainy and dry seasons

• Volcanic eruptions

• Tidal waves

During which season does the Tonle Sap River flow into the Tonle Sap Lake?

• Winter

• Summer

• Rainy season

• Dry season

What happens to the Tonle Sap River during the dry season?

• It floods the surrounding areas

• It reverses its flow

• It flows into the lake

• It dries up completely

Why is the biannual flow reversal of the Tonle Sap River important for local communities?

• It prevents flooding

• It generates hydroelectric power

• It supports fishing and agriculture

• It provides a source of drinking water

How is climate change expected to affect the Tonle Sap River's flow patterns?

• The river will flow more frequently

• The river will stop changing direction

• The river will change direction more drastically

• The river will change direction less drastically

What could help communities around the Tonle Sap River adjust their agricultural plans?

• Building more dams
