| soil surface sealing Any activity or process in which ground surface areas are packed or plugged to prevent percolation or the passage of fluids | etanşeitatea suprafeţei solului |
| surface-active agent A substance that, when used in small quantities, modifies the surface properties of liquids or solids. A surface-active agent reduces surface tension in a fluid or the interfacial tension between two immiscible fluids, such as oil and water. Surfactants are particularly useful in accomplishing the wetting or penetration of solids by aqueous liquids and serve in the manner of detergent, emulsifying, or dispersing agents. They are more effective than soap in certain situations and are used by conservators for such purposes as cleaning, wetting, and dispersing | agent tensioactiv |
| surface active compound Any soluble substance composed of two or more unlike atoms held together by chemical bonds that reduces interfacial tension between liquids or a liquid and a solid, often used as detergents, wetting agents and emulsifiers | compus tensioactiv |
| surface contamination | contaminare de suprafață |
| surface runoff Water that travels over the soil surface to the nearest surface stream; runoff of a drainage basin that has not passed beneath the surface since precipitation | scurgere de suprafaţă |
| surface sealing | acoperire |
| surface tension The force acting on the surface of a liquid, tending to minimize the area of the surface; quantitatively, the force that appears to act across a line of unit length on the surface. Also known as interfacial force; interfacial tension; surface intensity | tensiune superficială |
| surface treatment Any method of treating a material (metal, polymer, or wood) so as to alter the surface, rendering it receptive to inks, paints, lacquers, adhesives, and various other treatments, or resistant to weather or chemical attack | tratament de suprafaţă |
| surface water All waters on the surface of the Earth found in streams, rivers, ponds, lakes, marshes or wetlands, and as ice and snow | apă de suprafaţă |
| surface water management The administration or handling of water naturally open to the atmosphere (rivers, lakes, reservoirs, ponds, streams, seas, etc.) | management al apelor de suprafaţă |
