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.
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 ...
Cross section of a slope with soil nails installed. Soil nailing is a remedial construction measure to treat unstable natural soil slopes or unstable man-made (fill) slopes as a construction technique that allows the safe over-steepening of new or existing soil slopes.
The builder's level measures neither horizontal nor vertical angles. It simply combines a spirit level and telescope to allow the user to visually establish a line of sight along a level plane. When used together with a graduated staff it can be used to transfer elevations from one location to another.
The 41-yard-wide circular green surface itself is laid over nearly 600 actuators which use hydraulics to change the slope of the green from hole to virtual hole, so that no two hole approaches and ...
A level architectural deck may be intended for use by people, e.g., what in the UK is usually called a decked patio. "Roof deck" refers to the flat layer of construction materials to which the weather impervious layers are attached to a form a roof, and they may be either level (for a "flat" rooftop) or sloped.
Escarpment – Steep slope or cliff separating two relatively level regions (scarp) Esker – Long, winding ridge of stratified sand and gravel associated with former glaciers; Estuary – Partially enclosed coastal body of brackish water; Exhumed river channel – Ridge of sandstone that remains when the softer flood plain mudstone is eroded away
