• meander

The curve of bend in a stream formed when a stream’s slope decreases, water builds up in the stream channel, and moving water erodes away the sides of the streambed.

• delta

• aquifer

Water that flows downslope on Earth’s surface and may enter a stream, river, or lake; its rate is influenced by the angle of the slope, vegetation, rate of precipitation, and soil composition.

• aquifer

• runoff

• meander

• permeability
