A "Delta", so-called because of the tendency of the 'channels' created by hydrologic soil deposition to frequently vary their courses due to creation of impedences to linear flow caused by precipitation of the colloidally-suspended particles of soil which fall out of suspension as the velocity of the water is reduced, raising the floor of the channels, thus forcing the flow to seek an easier [more lateral] route. "Delta" is used in a mathematical sense, meaning "variation".
