Hydrological Role
- Water Source
- The Iguazu River, which feeds the falls, originates in a large watershed that captures rainfall from the surrounding region.
- This continual influx of water sustains the flow of the falls throughout the year, influencing seasonal variations.
- The Iguazu River, which feeds the falls, originates in a large watershed that captures rainfall from the surrounding region.
- Flow Regulation
- The falls act as a natural regulator of water flow, moderating river water levels downstream.
- During heavy rainfall, the falls buffer against potential flooding by absorbing excess water.
- The falls act as a natural regulator of water flow, moderating river water levels downstream.
- Sediment Transport
- Iguazu Falls contributes to sediment transport, redistributing sediments from upstream.
- This process shaped the riverbed and surrounding terrain over centuries, impacting local geology.
