Part 629 – Glossary of Landform and Geologic Terms
Title 430 – National Soil Survey Handbook Part 629 – Glossary of Landform and Geologic Terms Subpart A – General Information 629.0 Definition and Purpose This glossary provides the NCSS soil survey program, soil scientists, and natural resource specialists with landform, geologic, and related terms and their definitions to— (1) Improve soil landscape description with a standard, single source landform and geologic glossary. (2) Enhance geomorphic content and clarity of soil map unit descriptions by use of accurate, defined terms. (3) Establish consistent geomorphic term usage in soil science and the National Cooperative Soil Survey (NCSS). (4) Provide standard geomorphic definitions for databases and soil survey technical publications. (5) Train soil scientists and related professionals in soils as landscape and geomorphic entities. 629.1 Responsibilities This glossary serves as the official NCSS reference for landform, geologic, and related terms. The staff of the National Soil Survey Center, located in Lincoln, NE, is responsible for maintaining and updating this glossary. Soil Science Division staff and NCSS participants are encouraged to propose additions and changes to the glossary for use in pedon descriptions, soil map unit descriptions, and soil survey publications. The Glossary of Geology (GG, 2005) serves as a major source for many glossary terms. The American Geologic Institute (AGI) granted the USDA Natural Resources Conservation Service (formerly the Soil Conservation Service) permission (in letters dated September 11, 1985, and September 22, 1993) to use existing definitions. Sources of, and modifications to, original definitions are explained immediately below. 629.2 Definitions A.

GEOLOGY: N. M. FENNEMAN 17 PHYSIOGRAPHIC SUBDIVISION OF THE UNITED STATES By Nevin M. Fenneman DEPARTMENT OF GEOLOGY, UNIVERSITY OF CINCINNATI Communicated by W. M. Davis, November 24, 1916 Various attempts at subdivision of the United States into physio- graphic provinces have been made, beginning with- that of Powell.' The Association of American Geographers, recognizing the fundamental importance of this problem, appointed a committee in 1915 to prepare a suitable map of physiographic divisions. The committee consists of Messrs. M. R. Campbell and F. E. Matthes of the U. S. Geological Survey and Professors Eliot Blackwelder, D. W. Johnson, and Nevin M. Fenneman (chairman). The map herewith presented and the ac- companying table of divisions constitute the report of that committee. The same map on a larger scale (120 miles to the inch) will be found in Volume VI of the Annals of the Association of American Geographers, accompanying a paper by the writer on the Physiographic Divisions of the United States. In that paper are given the nature of the bound- ary lines and those characteristics of the several units which are believed to justify their recognition as such. Though the above-named com- mittee is not directly responsible for the statements there made, many of them represent the results of the committee's conferences. The paper as a whole is believed to represent fairly well the views of the committee, though in form the greater part of it is a revision of a former publication.2 The basis of division shown on this map, here reproduced, is physio- graphic or, as might be said in Europe, morphologic. -

Amar Kumar Kathwas*, Nilanchal Patel* Geomorphic Control on Soil Erosion – a Case Study in the Subarnarekha Basin, India
POLISH JOURNAL OF SOIL SCIENCE VOL. LIV/1 2021 PL ISSN 0079-2985 DOI: 10.17951/pjss/2021.54.1.1 AMAR KUMAR KATHWAS*, NILANCHAL PATEL* GEOMORPHIC CONTROL ON SOIL EROSION – A CASE STUDY IN THE SUBARNAREKHA BASIN, INDIA Received: 09.04.2020 Accepted: 17.02.2021 1Abstract. Geomorphology depicts the qualitative and quantitative characteristics of both terrain and landscape features combined with the processes responsible for its evolution. Soil erosion by water involves processes, which removes soil particles and organic matter from the upper sheet of the soil surface, and then transports the eroded material to distant location under the action of water. Very few studies have been conducted on the nature and dynamics of soil erosion in the dif- ferent geomorphologic features. In the present investigation, an attempt has been made to assess the control of geomorphologic features on the soil loss. Universal Soil Loss Equation (USLE) was used to determine soil loss from the various geomorphological landforms. Principal component analysis (PCA) was implemented on the USLE parameters to determine the degree of association between the individual principal components and the USLE-derived soil loss. Results obtained from the investigation signify the influence of the various landforms on soil erosion. PC5 is found to be significantly correlated with the USLE-derived soil loss. The results ascertained significant association between the soil loss and geomorphological landforms, and therefore, suitable strate- gies can be implemented to alleviate soil loss in the individual landforms.

Geomorphology, Topography, Soils, and Climate of the Eastern US
Chapter 3. Barton D. Clinton, James M. Vose, Erika C. Cohen Geographic Considerations for Fire Management: Geomorphology, Topography, Soils, and Climate of the Eastern U.S. Introduction Across the eastern US, there is on average an estimated 36 Mg ha1 of dead woody fuel (Chojnacky et al. 2004). Variation in fuel type, size, and flammability across the region makes selection of treatment options critical for effective fuels management. The eastern U.S. is a complex landscape characterized by highly fragmented forests, large areas of wildland urban interface, and vast differences in geomorphology, topography, soils, and climate. For example, the coastal plain region is generally flat, has large areas of wetlands, and is derived from sedimentary parent material. By contrast, the Piedmont and Appalachian Mountain regions are derived primarily from igneous and metamorphosed igneous parent materials, have complex topography, and little or no wetlands. Thus, it is important to understand interactions among fuel management treatments and geographic regions, and matching treatment prescriptions with physical conditions is critical. Fire and fuel management options are constrained by complex interactions among physical, biological, and social parameters. Biological and social parameters can be altered to some degree by management activities, new technologies, and policies, whereas physical parameters are generally not easily altered. Except where major changes in physical parameters have been possible (e.g., drainage of hydric ecosystems in the costal plain), variation in physical parameters across geographic regions constrains fuel and fire management options among and within regions. The purpose of this chapter is to describe, compare, and contrast the geomorphology, climate, and soils of major physiographic regions in the eastern U.S.
