Quizplus · Accepted Answer

The functioning distributary channels in a river-dominated delta are known as the active lobe. This is where river sediment is actively being deposited and shaping the delta as it flows into the ocean. The abandoned lobe refers to an area of the delta where the distributary channels are no longer active and have been filled with sediment. Bird-foot delta refers to a specific type of delta where the depositional landform resembles a bird's foot. River-dominated delta is a general term for a delta that is dominated by fluvial (river) processes as opposed to other types of deltas dominated by wave or tidal processes.
