Annotated Definitions of Selected Geomorphic Terms and Related Terms of Hydrology, Sedimentology, Soil Science and Ecology
Waite R. Osterkamp, U.S. Geological Survey
Definitions, including those of technical terms, vary with the person or textbook providing them, and with the discipline in which they are used. Twenty years ago, when trying to apply inadequately defined terms to his own writings, lectures, and training courses, Waite Osterkamp realized the need for well-worded definitions of technical terms that can be used in a standard manner within a discipline or among disciplines of the natural sciences. Furthermore, he recognized that most dictionaries and glossaries, especially those in textbooks, often provide well-constructed definitions of technical terms but, owing to a need for brevity, offer little or no explanation of the processes that may yield the observed feature. In consequence, Dr. Osterkamp began to compile his own definitions of terms, including two or more wordings when a term is viewed differently by ecologists, for example, than by hydrologists. And because a definition has limited value to a student or young professional if there is no understanding of how a geomorphic feature formed or how a plant community developed, he expanded, or annotated, many of the definitions to provide information and insights into process.
The list of annotated definitions given here is the result of years of compilation – one term one day, perhaps two several days later. The list is selective, reflecting Dr. Osterkamp’s interests and experiences; thus it is incomplete but open-ended and subject to additions in the future. Suggestions for terms to be added are welcome.
