A geologic formation that has no interconnected openings and hence cannot receive or transmit water.
Industry:Weather
A test to determine hydrologic properties of the aquifer involving the withdrawal of measured quantities of water from, or addition of water to, a well and the measurement of resulting changes in head in the aquifer both during and after the period of discharge or additions.
Industry:Weather
A layer of saturated geologic materials that could yield water to springs or wells.
Industry:Weather
A group of two or more aquifers that are separated by aquitards or aquicludes.
Industry:Weather
A geologic formation that may contain water but is incapable of transmitting water in significant quantities.
Industry:Weather
The altitude along the instrument approach glide path of a landing aircraft from which the pilot will first see 500 ft of the approach light array.
Industry:Weather
The distance from which a pilot on the instrument approach glide path can see landing aids at the runway threshold.

The distance from which a pilot on the instrument approach glide path can see landing aids at the runway threshold.
Industry:Weather
The interval of time between two successive transits of the sun across a meridian. This interval is about four minutes longer than the sidereal day, largely because of the sun's apparent annual motion eastward along the ecliptic (actually, the earth's “westward” motion along its orbit), which motion delays the sun's return to meridional transit. Also, this interval is inconveniently nonuniform due to systematic variations in the earth's orbital speed around the sun and the sun's changing declination. The concept of the mean solar day has been invented to circumvent these practical difficulties.
Industry:Weather
Mean flow velocity, measured a short distance upstream of a hydraulic structure.
