Knowra Amazon Delta Amazon Delta The Amazon Delta is the broad river-mouth region where the Amazon and its distributaries meet the Atlantic Ocean. It includes a shifting network of channels, islands, wetlands, and estuaries.
Amazon River : The largest river by discharge, flowing across northern South America into the Atlantic Ocean. Its enormous discharge governs the delta’s channels, sediment transport, and freshwater plume.
Marajó Island : A large island in the Amazon estuary, separated from mainland Brazil by river channels. It is the delta’s most prominent island and helps define the estuary’s southern side.
Amazon River ferry : A passenger or cargo vessel that transports people and goods along the Amazon’s waterways. Water transport connects settlements scattered across the delta’s channels and islands.
Amazon rainforest deforestation : The clearing or degradation of forest across the Amazon Basin, often for agriculture, logging, or infrastructure. Upstream land change can alter runoff, erosion, and sediment delivery toward the delta.
River delta : A landform built where a river deposits sediment as it enters a standing body of water. The Amazon’s mouth is an unusually large, tide-influenced example of this landform.
Tocantins River : A major river of Brazil that flows north into the Pará River near the Amazon estuary. Its connection through the Pará system complicates the geography of the delta region.
Artisanal fishing : Small-scale fishing using locally operated boats, gear, and knowledge. Fishing sustains many communities around the delta’s estuaries and islands.
Amazon River dams : Dams constructed or proposed on the Amazon and its tributaries for hydropower and water control. Dams can change the timing and quantity of flows and sediment reaching the river mouth.
Amazon River plume : A vast mass of freshwater and suspended material carried from the Amazon into the Atlantic Ocean. The river’s influence extends far offshore beyond the delta’s channels and islands.
Pará River : A tidal waterway in northern Brazil that receives the Tocantins and connects with the Amazon estuary. It forms a major southern route through the wider Amazon mouth region.
