  • 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.

  • Burnswark Hill: the Opening Shot of the Antonine Reconquest of Scotland? John H
    Burnswark Hill: the opening shot of the Antonine reconquest of Scotland? John H. Reid and Andrew Nicholson This paper represents an interim report of the Burnswark Project that has utilised the techniques of battlefield archaeology to locate and accurately identify missiles across a substantial field of conflict in SW Scotland. The distribution, characteristics, dating and proposed historical context of these missiles are argued to support their use in a dramatic episode of ‘exemplary force’ by the Roman army. The magnitude of the event might be seen to be compatible with an emperor establishing his legitimacy as a military leader. The complex of earthworks at Burnswark Hill near Ecclefechan in E. Dumfriesshire has excited the curiosity of antiquarians for centuries1 and provoked debate amongst his- torians and archaeologists for the last half-century.2 The imposing flat-topped summit is completely enclosed by the denuded ramparts of an Iron Age fort which, at 7 ha, is the larg- est in Dumfriesshire. Almost 300 m above sea level, the fort commands outstanding views of the Solway Basin and Annandale. Besides being the largest hillfort in SW Scotland, it is exceptional because it is held in the grip of two Roman camps of unusual morphol- ogy that straddle it to the north and south. The massive nature of the upstanding Roman earthworks, their extraordinary ‘artillery platforms’, and their positioning in relation to the hillfort are a unique juxtaposition in Europe. Archaeological investigations were first carried out in the late 19th c.; smaller-scale excavations took place in the early to mid-20th c., followed by the wide-ranging investigation by G.

  • Sediment Measurements
    Water Quality Monitoring - A Practical Guide to the Design and Implementation of Freshwater Quality Studies and Monitoring Programmes Edited by Jamie Bartram and Richard Ballance Published on behalf of United Nations Environment Programme and the World Health Organization © 1996 UNEP/WHO ISBN 0 419 22320 7 (Hbk) 0 419 21730 4 (Pbk) Chapter 13 - SEDIMENT MEASUREMENTS This chapter was prepared by E. Ongley. Sediments play an important role in elemental cycling in the aquatic environment. As noted in Chapter 2 they are responsible for transporting a significant proportion of many nutrients and contaminants. They also mediate their uptake, storage, release and transfer between environmental compartments. Most sediment in surface waters derives from surface erosion and comprises a mineral component, arising from the erosion of bedrock, and an organic component arising during soil-forming processes (including biological and microbiological production and decomposition). An additional organic component may be added by biological activity within the water body. For the purposes of aquatic monitoring, sediment can be classified as deposited or suspended. Deposited sediment is that found on the bed of a river or lake. Suspended sediment is that found in the water column where it is being transported by water movements. Suspended sediment is also referred to as suspended matter, particulate matter or suspended solids. Generally, the term suspended solids refers to mineral + organic solids, whereas suspended sediment should be restricted to the mineral fraction of the suspended solids load. Sediment transport in rivers is associated with a wide variety of environmental and engineering issues which are outlined in Table 13.1.
