North Carolina covers 53,819 square miles (139,391 km 2) and is 503 miles (810 km) wide by 150 miles (241 km) long. The physical characteristics of the state vary from the summits of the Smoky Mountains, an altitude of near seven thousand feet (2,130 m) in the west, sloping eastward to sea level along the coast and beaches of the Atlantic Ocean .
One possible way of assessing soil thermal properties is the analysis of soil temperature variations versus depth Fourier's law, Q = − λ d T / d z {\displaystyle Q=-\lambda dT/dz\,} where Q is heat flux or rate of heat transfer per unit area J·m −2 ∙s −1 or W·m −2 , λ is thermal conductivity W·m −1 ∙K −1 ; dT / dz is the ...
North Carolina averages 5 inches (130 mm) of snow per winter season. However, this varies greatly across the state. Along the coast, most areas register less than 2 inches (51 mm) per year while the state capital, Raleigh, averages 6.0 inches (150 mm). Farther west in the Piedmont-Triad, the average grows to approximately 9 inches (230 mm).
The frost line —also known as frost depth or freezing depth —is most commonly the depth to which the groundwater in soil is expected to freeze. The frost depth depends on the climatic conditions of an area, the heat transfer properties of the soil and adjacent materials, and on nearby heat sources. For example, snow cover and asphalt ...
North Carolina Highway 681 (NC 681) was established in 1928 as a renumbering of part of NC 68; traveling from NC 68/NC 69, in Jefferson, to the Virginia state line, at Grassy Creek. [11] In 1931, Virginia established SR 139 to connect with NC 681 at the state line, which continued to Mouth of Wilson .
The American Association of State Highway and Transportation Officials ( AASHTO) is a standards setting body which publishes specifications, test protocols, and guidelines that are used in highway design and construction throughout the United States. Despite its name, the association represents not only highways but air, rail, water, and public ...
