Headward erosion is the process by which a stream channel lengthens up its slope as erosion moves headward (upstream) into the landscape. As the stream erodes the land, its channel becomes longer and the stream's drainage area becomes larger. Downstream piracy refers to when one stream diverts the waters of another stream to itself. Downcutting is the process by which a stream cuts downward into its bed, creating a deeper channel. Infiltration refers to the process of water soaking into the ground.
