l = slope length α = angle of inclination. The grade (US) or gradient (UK) (also called stepth, slope, incline, mainfall, pitch or rise) of a physical feature, landform or constructed line is either the elevation angle of that surface to the horizontal or its tangent. It is a special case of the slope, where zero indicates horizontality. A ...
Section through railway track and foundation showing the sub-grade. Grading in civil engineering and landscape architectural construction is the work of ensuring a level base, or one with a specified slope, [1] for a construction work such as a foundation, the base course for a road or a railway, or landscape and garden improvements, or surface drainage.
Slope illustrated for y = (3/2)x − 1.Click on to enlarge Slope of a line in coordinates system, from f(x) = −12x + 2 to f(x) = 12x + 2. The slope of a line in the plane containing the x and y axes is generally represented by the letter m, [5] and is defined as the change in the y coordinate divided by the corresponding change in the x coordinate, between two distinct points on the line.
Tobler's hiking function – walking speed vs. slope angle chart. Tobler's hiking function is an exponential function determining the hiking speed, taking into account the slope angle. [1] [2] [3] It was formulated by Waldo Tobler. This function was estimated from empirical data of Eduard Imhof. [4]
where is the equivalent stress, is the pressure, is the pre-consolidation pressure, and is the slope of the critical state line in space. The pre-consolidation pressure evolves as the void ratio ( e {\displaystyle e} ) (and therefore the specific volume v {\displaystyle v} ) of the soil changes.
The site for St John's College is on top of a hill. Originally a small crops farm, the only building on the site was a small farm house. Purchased by St Joseph's Parish in 1963, it was many years before the land was developed. Originally the plan was to build the school on the slope of the hill and have playing fields on the top.
Slope house, the different floors have ground floor in different levels. The lower floor is partly underground. Slope house or Souterrain house is a house with soil or rock completely covering the bottom floor on one side and partly two of the walls on the bottom floor. The house has two entries depending on the ground level.
Trees showing the presence of creep. Downhill creep, also known as soil creep or commonly just creep, is a type of creep characterized by the slow, downward progression of rock and soil down a low grade slope; it can also refer to slow deformation of such materials as a result of prolonged pressure and stress.
