Abstract Physiography has been studied in the United States for more than 75 years, but only recently has it been applied to land use planning. Advantages of a physiographic approach are that it 1) focuses on the problems at the proper scale and conserves energy, effort, and time by selecting the critical parameters, 2) stresses geologic structure and process as factors which should control land use, and 3) presents data in a form which the non-geologically trained planner can easily understand. In 1928 Fenneman delineated and described the provinces and sections of the United States. This paper proposes a classification of smaller physiographic units and presents two examples of how they can be used for planning purposes. Below the section, the units used in this paper are the subsection, the land type, and the topographic element. Subsections delineate areas of distinct geologic structure or process whereas land types delineate ranges in the intensity of those processes. Topographic elements delineate units with distinct ranges of slopes or shapes of slopes, such as concave or convex.
