Available Relief and Texture of Topography a Discussion

Abstract

Attention is directed to a recent discussion of "available relief," "critical relief.' and "drainage relief." Suggestions are made for redefining two of the terms, and the factors involved in the development of relief are examined. It is shown that the spacing of drainage lines (texture of topography) is a factor of prime importance in determining quantity of relief, and that available relief may vary greatly with differences in stream spacing. Finally, it is suggested that stages of landmass dissection should be expressed in terms of the amount of mass removed, not in terms of amount of upland surface destroyed; and it is concluded that available relief offers a useful basis for judging the progress of landmass removal.
