16: running water Flashcards
the land are that contributed water to a stream is called a
drainage basin
a steep walled notch in a ridge through which a stream flows
water gap
the flow of water in a stream can be
laminar or turbulent
capacity refers to
the amount of sediment a river can hold
competence refers to
the size of sediment or particles the river is carrying
sediment deposited by streams is called
alluvium
meanders are enhanced through erosion at the
cut bank
braided channels occur in streams that experience
highly variable discharge
includes the channel itself, adjacent floodplain, and steep valley walls
stream valley
streams erode downward until they reach
base level
a stream that has reached equilibrium with its base level and primarily works to transport sediment
graded stream
streams underlain by deep alluvium are likely to develop
terraces
what may form when a river deposits sediment into the mouth of another body of water
a delta
what results from sediment being deposited along the margins of a river channel by many years of successive floods
natural levees
fan shaped deposits of alluvium that form where steep mountain fronts drop down into adjacent valleys
