MeanderingMeandering• When a river flowing through a

floodplain typically winds back and forth in curves.

Natural LeveesNatural Levees• During a flood a river carries

sediment and it is deposited and it builds up along the stream and forms elevated ridges.

Water TableWater Table• The surface below

which the ground is saturated with water.

WellsWells• Artesian

Formation- an arrangement of permeable layer of rock sandwiched between two layers of impermeable rock.

Transport materialTransport material• Load- Eroded rock

and soil materials that are transported downstream by a river.

Transport materialTransport material• Suspension- Rock

materials carried by a river are stirred up and kept from sinking by the turbulence of stream flow.

Transport materialTransport material• Bed load- Sand

pebbles and boulders that are moved along the bed of a stream and that are too heavy to be carried in suspension.

DepositionDeposition• Delta- fan- shaped deposit that form

when a river flows into a quiet or large body of water.

DepositionDeposition• Alluvial Fan- forms when a steep

mountain stream meets dry, level land at the base of the mountain.

Review QuestionsReview Questions1. What is meandering and what landforms

does it make?- Rivers that curve.2. What are natural levees and how do they

form?- Elevated ridges along rivers that form by

floods.3. What 3 ways can rivers move the earth?Sediment load, Bed load, & Dissolve load

Review QuestionsReview Questions4. What is the water table?- The upper surface of the zone of saturation

affected by water going in and out.5. How does a well change the water table?- The water table gets sucked in.6. What is an artesian well?- An arrangement of permeable layer of rock

sandwiched between two layers of impermeable rock.
