• breakwater
artificial barrier built in the water parallel to shore that reduces beach erosion by incoming waves
• floodplain
broad flat area on both sides of a river where it deposits its sediments when it floods its banks
• sinkhole
circular hole in the surface of the ground that forms when the roof of a cave collapses

• deposition
process by which eroded sediments are dropped somewhere else by an agent of erosion
• levee
raised strip of sediments deposited along the bank of a river when it overflows its channel
• traction
transport of large particles such as gravel and stones by rolling or dragging along the bottom of the wat... • barrier island: long, narrow island that forms parallel to shore when a sandbar builds up enough to rise above the water's surface
• erosion
transport of sediments by moving water, wind, glaciers, or gravity
• saltation
transport of small particles such as sand in little jumps along a streambed
• suspension
transport of very small particles such as clay that are carried by the main stream flow but are not dissolved by the water
• delta
triangular landform created where a river empties into a body of still water and deposits its sedimen
• cave
underground hole or cavern eroded by groundwater
