The thermodynamic basis of entropy concepts as applied in fluvial geomorphology is examined closely. It is shown that the principle of minimum entropy production rate and the principle that the most probable state of a system is that which corresponds to a maximum of entropy are not applicable in stream situations. It is concluded that the use of entropy as an approach to stream behavior and sediment transport is of dubious validity.
