A- Competence is how big the particles are in a stream and capacity is how much sediment is transported.

B- Competence is a measure of how large a particle the stream is capable of transporting whereas capacity is a measure of the volume of water in a stream.

C- Competence deals with the ease at which water flows through a channel. It is dependent on how straight the river is and how smooth the bed is. Capacity is a measure of the total discharge of the river.

D- Competence is how efficiently a stream carries sediments in its channel and capacity is dependent on how fast the water is flowing
