along straight stretches, the highest velocities are near the ______ of the channel just below the surface
a stream's gradient, shape, size, & roughness of its channel are all factors that determine the ________ of a stream
as the size of the channel __________, (increases or decreases) there is less friction & the H2O flows more swiftly
the lowest point to which a stream can erode its channel; the level at which the mouth of a stream enters the ocean, lake, or another stream
a bend in the course of a stream; a stream in a broad, flat-bottomed valley that is near its base level often develops a course w/ many bends called
streams generally erode their channels by lifting loose particles by: (3- a,g, & dsm)
abrasion, grinding, & dissolving soluble material
streams can transport sediment in 3 ways. 3)scooting or rolling along the bottom (___ ____)
part of a stream's 'load' of solid material that is made up of sediment too large to be carried in suspension
occurs as streamflow drops below the critical setting velocity of a certain particle size
most of the erosion occurs on the outside of the meander--often called the ___ ____--where velocity & turbulence are greatest
occurs when the discharge of a stream b/c so great that it exceeds the capacity of its channel and overflows its banks
new, shorter channel segment is called a cutoff &, b/c of its shape, the abandoned bend is called an
measures to control flooding include (3: al, fcd, & plofd))
artificial levees, flood control dams, & placing limits on floodplain development
an intermittent hot sprong or fountain in which a column of water shoots up with great force at various intervals
naturally formed underground chamber; when groundwater comes in contact w/ llimestone, the carbonic acid
the deposition of dripstone features is not possible until the caverns are above the water table in the
zone of aeration
many areas of the world have landscapes that have been shaped laregly by dissolving power of groundwater
if you were to examine the profile of a typical stream, you would probably find that the gradient is
steepest near the head
occasionally, deposition causes the main channel of a stream to divide into several smaller channels called
