Seite 18 - ... for the day when the mean gage height was highest. As the gage height is the mean for the day, it does not indicate correctly the stage when the water surface was at crest height, and the corresponding discharge was consequently larger than given in the maximum column. Likewise, in the column of "Minimum" the quantity given is the mean flow for the day when the mean gage height was lowest. The column headed "Mean" is the average flow in cubic feet for each second during the month.

Seite 28 - DEFINITION OF TERMS. The volume of water flowing in a stream — the "run-off" or "discharge" — is expressed in various terms, each of which has become associated with a certain class of work. These terms may be divided into two groups — (1) those which represent a rate of flow, as secondfeet, gallons per minute, miner's inches, and...

Seite 17 - Second-feet per square mile" is. the average number of cubic feet of water flowing per second from each square mile of area drained, on the assumption that the run-off is distributed uniformly both as regards time and area. "Run-off in inches...

Seite 29 - ... they also give, as far as possible, a complete history of all the changes that have occurred since the establishment of the station that would be factors in using the data collected. The discharge-measurement table gives the results of the discharge measurements made during the year, including the date...

Seite 29 - Run-off" (depth in inches) is the depth to which the drainage area would be covered if all the water flowing from it in a given period were conserved and uniformly distributed on the surface. It is used for comparing run-off with rainfall, which is usually expressed in depth in inches. An "acre-foot...

Seite 331 - The elevations in the following list are based on an aluminum tablet marked "1984 ATLANTA" at the northeast corner of front vestibule of Towns County court-house, Hiwassee, the elevation •of which is accepted as 1,983.634 feet above sea level.

(2) The top of a stone post set into the ground on the north side of the river, about 300 feet from the end of the iron bridge and on the west side of the road leading toward Carter's mill; elevation, 22.15 feet. 'Elevations refer to the datum of the gage. Discharge measurements of Coosawaltee River at Carters.

Seite 72 - WS 155. Fluctuations of the water level in wells, with special reference to Long Island, New York, by AC Veatch.

Seite 16 - As the discharge is the product of two factors, the area and the mean velocity, any change in either factor will produce a corresponding change in the discharge. Their curves are therefore constructed in order to study each independently of the other. The area curve can be definitely determined from accurate soundings extending to the limits of high water. It is always concave toward the horizontal axis...
