Making concepts more explicit for geomorphology

The nature, prevalence and function of concepts in geomorphology are reviewed. Following definition of the term, we consider how and where concepts have been used, and how their usage may be structured. While geomorphology is rich in conceptual ideas, many are informally held and can often remain untested by conventional scientific methods. It is concluded that concepts should receive greater specific recognition and examination, both to enhance the science of geomorphology and also for pedagogic reasons because key conceptual ideas can inspire student interest prior to the demanding levels of technical learning that the subject now demands.
