subsurface | - Below the surface of the water, submerged, underwater.
- Beneath the surface of the earth.
- An underground workplace.

subsurface correlation |
|
|
subsurface corrosion | Formation of isolated particles of corrosion products beneath the metal surface. this results from the preferential reaction of certain alloy constituents by inward diffusion of oxygen, nitrogen and sulfur. |
|
subsurface course | The top course of pavement providing a surface which is resistant to traffic abrasion. |
|
subsurface dam | Плотина подземных вод |
|
subsurface discharge | Поля подземной фильтрации (для отведения сточных вод под землю) |
|
subsurface discontinuity | - Discontinuity not open to the surface. see also near-surface discontinuity.
- Discontinuity not open to the surface.
- Near-surface discontinuity.

|
|
subsurface fatigue | - Fatigue cracking that originates below the surface. usually associated with hard surfaced or shot peened parts but may occur any time subsurface stresses exceed surface stresses. t

|
subsurface sand filter | A wide bed, consisting of a number of lines of perforated pipe or drain tile surrounded by clean coarse aggregate, containing an intermediate layer of sand as filtering material, and provided with a system of underdrains for carrying off the filtered sewage. |
|
subsurface sewage disposal system | A system for the treatment and disposal of domestic sewage by means of a septic tank and a soil absorption system. |

|
subsurface stabilization fabrics | - Fabrics used in the construction on access roads, railroads, parking and storage areas over soft, unstable soil. the fabric is placed between the subgrade and the stabilizing fill material where it provides separation of subsoil and fill, filtration of moisture at the subsoil/fill interface, and added tensile reinforcement of the compacted fill.
