The amount of water flowing past a point along the stream over a given interval of time is called the streamâs discharge. In general, discharge increases downstream as tributaries empty into and add their discharge to the stream.

The relationship of discharge at any point along the stream to its channel and its velocity is given by the equation:

Discharge(cfs) = stream width (ft) X depth (ft) X velocity ( ft )

Also moving with the water are the sediments being transported by the stream, its load.

The streamâs load consists of several components.

Bed load

Suspended load

Dissolved load

The bed load consists of sand through boulder size sediments which move either by traction (rolling sliding, or dragging) or saltation (bouncing)

The amount of load that a stream can carry is related primarily to the amount of water flowing through it (discharge) and the velocity of the flow.

The size of sediment that the stream can carry is related to the velocity of its flow

The constant washing action of water tumbles rocks and stones together and smooths the rough edges away.The particles sink into the water and this is classed as sediment .The sediment is washed down stream and settles into the bed of the river.Over the years this builds up into a deep silt .When the water levels recede the silt drys out and hardens into a new rock face. It is part of an evolutionary process.
