Down: 2) A lake that was formerly part of the channel of the meandering stream; isolated when a stream eroded its outer bank, forming a cutoff through the neck of the looping meander3) refers to coarser materials that are dragged and pushed and rolled along the streambed by traction or that bounce and hop along by saltation4) low depositional ridges on the banks of streams that develop as by-products of flooding. As floodwaters rise, the river overflows its banks, loses stream competence and capacity as it spreads out, and drops a portion of its sediment load, which form the levees5) The mouth of a river is where it reaches base level. The river’s velocity rapidly decelerates as it enters a larger, standing body of water. The reduced stream competence and capacity cause deposition of the sediment load. Coarse sediment such as sand and gravel drops out first and is deposited closest to the river’s mouth. Finer clays are carried farther and form the extreme end of the deposit, which may be subaqueous, or underwater even at low tide9)  greatest near the channel boundary where the turbulence is being generated and declines away from the bed towards the water surface11) when the mouth of a river enters the sea and is inundated by seawater in a mix with freshwater12) the lowest elevation limit of stream erosion in a region14) streams that originate in a humid region and flow through an arid region, resulting in discharge that decreases with distance15) when the water recedes, it leaves behind alluvial deposits that generally mask the underlying rock with their accumulating thickness. The present river channel is embedded in these alluvial deposits. When floodwaters rise, the river overflows its banks, loses stream competence and capacity as it spreads out, and drops a portion of its sediment load to form the levees. Larger, sand-sized particles drop out first, forming the principal component of the levees, with finer silts and clays deposited farther from the river.17) Solution refers to the dissolved load of a stream, especially the chemical solution derived from minerals such as limestone or dolomite or from soluble salts The suspended load consists of fine grained, clastic particles held aloft in the stream o Bed load refers to coarser materials that are dragged and pushed and rolled along by the streambed by traction or that bounce and hop along by saltation If a load in stream exceeds its capacity, sediment accumulates as aggradation as the stream channel builds through deposition 19) A dry valley once occupied by a stream or river, since captured by another stream Across: 1) an interruption in a stream’s longitudinal profile6) .002 mm7) The mouth of a river is where it reaches base level. The river’s velocity rapidly decelerates as it enters a larger, standing body of water. The reduced stream competence and capacity cause deposition of the sediment load. Coarse sediment such as sand and gravel drops out first and is deposited closest to the river’s mouth. Finer clays are carried farther and form the extreme end of the deposit, which may be subaqueous, or underwater even at low tide8) the general term for the clay, silt sand, gravel, or other unconsolidated rock and mineral fragments deposited by running water as sorted or semi-sorted sediment on a floodplain, delta, or streambed9) a stream are near the surface at center channel, corresponding to the deepest part of the stream channel. The portion of the stream flowing at maximum velocity moves diagonally across the stream from bend to bend in a meandering stream.10) visible to eye; .06 mm13) when a channel has just enough energy to transport its sediment load16) when the water recedes, it leaves behind alluvial deposits that generally mask the underlying rock with their accumulating thickness. The present river channel is embedded in these alluvial deposits. When floodwaters rise, the river overflows its banks, loses stream competence and capacity as it spreads out, and drops a portion of its sediment load to form the levees. Larger, sand-sized particles drop out first, forming the principal component of the levees, with finer silts and clays deposited farther from the river.17) .01 mm; can’t be seen18) the outer portion of each meandering curve is subject to the fastest water velocity and therefore the greatest scouring erosive action. In contrast, the inner portion of a meander experiences the slowest water velocity and thus receives sediment fill, forming a point bar deposit 20) the basic spatial geomorphic unit of a river system; distinguished from a neighboring basin by ridges and highlands that form divides, marking the limits of the catchment area21) closer to the sides and bottom of the channel because of the frictional drag on the water flow22) the lowest elevation limit of stream erosion in a region
