Silt is one type of material found on the bottom of a stream. Silt is fine and can be carried along in moving water, but is heavyier than water, so settles out of the water as it slows. It can be organic or mineral.
Stream Load is the amount of material a stream can hold as it flows. As a stream flows it causes erosion, and this erosion is carried about as material in the stream. As too much is eroded, the extra material will fall to the bottom, or push it's way to the sides.
A stream bed is the bottom (floor) of the stream.

A stream bed is the bottom of a stream where water flows, while a stream bank is the sides of the stream that contain and channel the flow of water. The stream bed is where water flows, whereas the stream bank is the boundary that contains the water within the stream channel.
