Document Summary
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: 2) delta- 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. Be familiar with the types and the physical geography associated with each: 7 most common drainage patterns, dendritic- most familiar; treelike pattern (from the greek word dendron, meaning.
