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. Reference Codes Sources from which definitions were taken, whole or in part, are identified by a code (e.g., GG) following each definition.

The Levee Was Sparsely Vegetated by Pioneering Species Like Blazing Star, Russian Thistle, Sweet White Clover, and Seedlings Of
Upper Carson River Watershed Stream Corridor Assessment The levee was sparsely vegetated by pioneering species like blazing star, Russian thistle, sweet white clover, and seedlings of mountain big sagebrush and rubber rabbitbrush. Large, mature black cottonwoods occupied the stream terrace at the upper cross section location on the right side, providing picnic and camp sites for area recreationists. Past beaver activity (+/-10 years) was indicated by a 12 inch diameter cottonwood stump. The herabaceous understory was sparse to absent. The topographic depression located between the levee and the highway was developing into an emergent wetland community dominated by cattail. At the higher end of this depression (where it was drier), a large stand of bull thistle was present. Coyote willows also occupied the drying end of this area. A woody regeneration transect was established adjacent to the right side of the river on an elevated terrace. Mature black cottonwood provided an almost continuous canopy cover. The age class distribution of the woody species showed a ratio of approximately 2.7:1 sprout and saplings to mature, decadent, and dead black cottonwood, woods rose, mountain alder and willow species. Data developed as part of the present study (Table 4.10) indicate that the area is dominated by early and mid successional status ratings. Vegetation in the area is adjusting to past disturbances (recreation) and current fluvial processes. Table 4.10. Reach EF7 successional status data. Successional Percent Status Occurrence Early 43.4 Mid 32.9 High 23.8 A management recommendation would be to remove the existing bull thistle stand and monitor to prevent its reestablishment.

Bag of Geomorphological Words: a Framework for Integrating Terrain

Previous research investigations concerning geomorphological variables and region-level features alone cannot precisely characterize the main structure of landforms. However, these geomorphological variables are not sufficient to represent a complex landform object’s whole structure from a high-resolution DEM. Moreover, the amount of the DEM dataset is limited, including the landform object. Considering the challenges above, this paper reports an integrated model called the bag of geomorphological words (BoGW), enabling automatic landform recognition via integrating point and linear geomorphological variables, region-based features (e.g., shape, texture), and high-level landform descriptions.

METHODS AND APPLICATIONS IN SURFACE DEPRESSION ANALYSIS * Susan K. Jenson TGS Technology, Inc. Sioux Falls, South Dakota 57198 and Charles M. Trautwein U.S. Geological Survey EROS Data Center Sioux Falls, South Dakota 57198 ABSTRACT Gridded surface data sets are often incorporated into digital data bases, but extracting information from the data sets requires specialized raster processing techniques different from those historically used on remotely sensed and thematic data. Frequently, the infor mation desired of a gridded surface is directly related to the topologic peaks and pits of the surface. A method for isolating these peaks and pits has been developed, and two examples of its application are presented. The perimeter of a pit feature is the highest-valued closed contour surrounding a minimum level. The method devised for finding all such contours is designed to operate on large raster surfaces. If the data are first inversely mapped, this algorithm will find surface peaks rather than pits. In one example the depressions, or pits, expressed in Digital Elevation Model data, are hydrologically signifi cant potholes. Measurement of their storage capacity is the objective. The potholes are found and labelled as polygons; their watershed boundaries are found and attributes are computed. In the other example, geochemical surfaces, which were interpolated from chemical analyses of irregularly distributed stream sediment samples, were analyzed to determine the magnitude, morphology, and areal extent of peaks (geochemical anomalies).

The site is 360 km west of the well-known Wadi Hitan site. A preliminary faunal inventory suggests the cetacean fauna to be roughly comparable to the fauna recorded at Wadi Hitan; other faunal elements however are indicative of a distinctively different palaeoenvironmental setting.

Noller Oregon State University Corvallis, Oregon Sarah J. Hash Forest Service Bend, Oregon Karen Bennett Forest Service Portland, Oregon December 2013 ver. 0.7 DRAFT Note to the Reader This provisional, draft text presents and briefly describes the terms used in the preparation of a map of landform groups covering all forests within Region Six of the US Forest Service. Formal definition of map units is pending completion of this map and review thereof by all of the forests in Region Six. Map unit names appended to GIS shapefiles are concatenations of terms defined herein and are meant to be objective descriptors of the landscape within each map unit boundary. These map unit names have yet to undergo a final vetting and culling to reduce complexity, redundancy or obfuscation unintentionally resulting from map creation activities.
