American Society of Civil Engineers; Abbreviation: ASCE: Founded: November 5, 1852; 172 years ago (): Type: Engineering society: Focus: Purpose of the group is the advancement of the science and profession of Civil engineering and the enhancement of human welfare through the activities of society members.
Soil texture is a classification instrument used both in the field and laboratory to determine soil classes based on their physical texture. Soil texture can be determined using qualitative methods such as texture by feel, and quantitative methods such as the hydrometer method based on Stokes' law.
USDA soil taxonomy provides the core criteria for differentiating soil map units. This is a substantial revision of the 1938 USDA soil taxonomy which was a strictly natural system. The USDA classification was originally developed by Guy Donald Smith, director of the U.S. Department of Agriculture's soil survey investigations. [7]
The project was led within NRCS by Clive Walker. The modeling work used the Soil & Water Assessment Tool (SWAT) developed by Jeff Arnold, Jimmy Williams and others at USDA-Agricultural Research Service (ARS) in Temple, Texas. Additional development support was provided by the Texas A&M Blackland Research & Extension Service AgriLife Center ...
USDA soil taxonomy (ST) developed by the United States Department of Agriculture and the National Cooperative Soil Survey provides an elaborate classification of soil types according to several parameters (most commonly their properties) and in several levels: Order, Suborder, Great Group, Subgroup, Family, and Series.
The United States Department of Agriculture (USDA) is an executive department of the United States federal government that aims to meet the needs of commercial farming and livestock food production, promotes agricultural trade and production, works to assure food safety, protects natural resources, fosters rural communities and works to end hunger in the United States and internationally.
[12] In 2003, ASCE changed the committee from a task basis to a standing committee; acknowledging the effort will take many years. [12] The 1999 committee had in fact recommended a 20-year timeframe. [12] This is committee was also charged in 2003 with implementing another ASCE initiative, "Raise the bar". [12]
