Surface water flow can include flow both in recognisable river channels and otherwie.

Surface water salinity ranges from 32 to 37 parts per 1000, the highest occurring in the Arabian Sea and in a belt between southern Africa and south-western Australia.

Surface water drains more easily on the levees ' backslope, and the coarse soils of the levees are easier to cultivate and permit better subsurface drainage.

Surface water temperatures on the Atlantic side reach a summer average of inshore and offshore to winter lows of inshore and offshore.

Surface waters, including the Rio Grande and other streams, are hydrologically connected to the " unconfined aquifer " a shallow ground water formation which underlies much of the valley.

* Surface lures, also known as top water lures.

Surface irrigation water normally contains salts in the order of 0. 5 g / l or more and the annual irrigation requirement is in the order of 10000 m < sup > 3 </ sup >/ ha or more so the annual import of salt is in the order of 5000 kg / ha or more.

* Surface roots: These proliferate close below the soil surface, exploiting water and easily available nutrients.

Surface processes comprise the action of water, wind, ice, fire, and living things on the surface of the Earth, along with chemical reactions that form soils and alter material properties, the stability and rate of change of topography under the force of gravity, and other factors, such as ( in the very recent past ) human alteration of the landscape.

Surface waves ( L-waves ) are analogous to water waves and travel along the Earth's surface.

Surface tension and hydrophobicity interact in this attempt to cut a water droplet.

Surface water withdrawals in Cherryfield from Crane Pond are also of concern as these are the headwaters of the Harrington River tributaries that flow through Columbia.

Surface water features include Harrison and Paw Paw Lakes in the northern part of the township.

Surface feeders in flight include some of the most acrobatic of seabirds, which either snatch morsels from the water ( as do frigate-birds and some terns ), or " walk ", pattering and hovering on the water's surface, as some of the storm-petrels do.

Surface pressure can also refer to the change of surface tension as a function of the area of water surface available to each molecule in a solution.

Surface water plants also generate sludge made up of solids removed from the raw water.

* Surface blowdown line: It provides a means for removing foam or other lightweight non-condensible substances that tend to float on top of the water inside the boiler.

Surface water ponds are also susceptible to contamination by ash.

Early in 1942, Wallis began experimenting with skipping marbles over water tanks in his garden, leading to his April 1942 paper " Spherical Bomb — Surface Torpedo ".

# Surface Water: Freshwater bodies that are open to the atmosphere and are not designated as groundwater are classified in the USA for regulatory and water purification purposes as surface water.

* Aegean Sea Surface Water – thick veneer, with summer temperatures of 21 – 26 ° C and winter temperatures ranging from in the north to in the south.

Surface temperatures behave absolutely differently ; the film of oil in the Wankel engine acts as insulation.

Surface temperatures for griddles using solid state thermostats are typically limited to for this reason.

Surface and air temperatures, insolation, and wind all affect this.

" Surface water temperatures have coincided by also peaking every twelve and a half years.

Surface temperatures vary from the high 60s (~ 20 ° C ) in winter to the high 70s (~ 25 ° C ) in summer.

Surface temperatures under the polar highs are the coldest on Earth, with no month having an average temperature of above freezing.

Surface and below-ground soil temperatures during a burn are generally higher than those of forest fires because the centers of combustion lie closer to the ground, although this can vary greatly.

Surface melting was found to begin at temperatures as low as − 33 ° C.

The day's next task was to deploy the Apollo Lunar Surface Experiments Package ( ALSEP ); while they were parking the lunar rover, on which the TV camera was mounted, to observe the deployment, the rear steering began functioning without explanation.

Still further south lies the Polar front, which is marked by a transition to very cold, relatively fresh, Antarctic Surface Water at the surface.

* Surface Loci concerned either loci ( sets of points ) on surfaces or loci which were themselves surfaces ; under the latter interpretation, it has been hypothesized that the work might have dealt with quadric surfaces.

Surface creep is the slow movement of soil and rock debris by gravity which is usually not perceptible except through extended observation.

Surface acoustic wave ( SAW ) devices are another kind of piezoelectric resonator used in crystal oscillators, which can achieve much higher frequencies.

Powers ’ U-2, which departed from a military airbase in Peshawar, Pakistan and may have received support from the US Air Station at Badaber ( Peshawar Airbase ), was shot down by an S-75 Dvina ( SA-2 Surface to Air ) missile on May 1, 1960, over Sverdlovsk.

Surface personnel often employ a piece of communications equipment called a " helium de-scrambler ," which electronically lowers the pitch of the diver's voice as it is relayed through the communications gear, making it easier to understand.

Surface waves have been used in over-the-horizon radar, which operates mainly at frequencies between 2 and 20 MHz over the sea, which has a sufficiently high conductivity to convey the surface waves to and from a reasonable distance ( up to 100 km or more ; over-horizon radar also uses skywave propagation at much greater distances ).

* Surface combatant-large, heavily armed surface ships which are designed primarily to engage enemy forces on the high seas, including various types of battleship, battlecruiser, cruiser, destroyer, and frigate.

Initially, two additional levels of representation were introduced ( LF — Logical Form, and PF — Phonetic Form ), and then in the 1990s Chomsky sketched out a new program of research known as Minimalism, in which Deep Structure and Surface Structure no longer featured and PF and LF remained as the only levels of representation.

By 2001, the various surface analyses done within the National Weather Service were combined into the Unified Surface Analysis, which is issued every six hours and combines the analyses of four different centers.

** Surface supplied diving, in which a diver uses an umbilical to breathe

Digital Land Surface Models should not be confused with Digital Surface Models, which can be surfaces of the canopy, buildings and similar objects.

Later, Meiko introduced M²VCS ( Meiko Multiple Virtual Computing Surfaces ), a multi-user resource management system which allowed the processors of a Computing Surface to be partitioned into several domains of different sizes.

In 1988, Meiko launched the In-Sun Computing Surface, which repackaged the Computing Surface into VMEbus boards ( designated the MK200 series ) suitable for installation in larger Sun-3 or Sun-4 systems.

Meiko also produced a SPARC processor board, the MK083, which allowed the integration of the SunOS operating system into the Computing Surface architecture, similarly to the In-Sun Computing Surface.

MeikOS was used in conjunction with the M²VCS ( Meiko Multiple Virtual Computing Surfaces ) resource management software which partitioned the processors of a Computing Surface into domains, managed user access to these domains, and provided inter-domain communication.

MeikOS was made obsolete by the introduction of the In-Sun Computing Surface and the Meiko MK083 SPARC processor board, which allowed SunOS and SVCS ( Sun Virtual Computing Surfaces, later developed as VCS ) to take over the roles of MeikOS and M²VCS respectively.

Surface feeding itself can be broken up into two different approaches, surface feeding while flying ( for example as practiced by gadfly petrels, frigatebirds and storm petrels ), and surface feeding whilst swimming ( examples of which are practiced by fulmars, gulls, many of the shearwaters and gadfly petrels ).
