Seite 15 - 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 tune and area. "Run-off in inches...
Seite 16 - ... (1 United States billion) cubic feet equals 11,570 second-feet for one day. 1,000,000,000 cubic feet equals 414 second-feet for one 28-day month. 1,000,000,000 cubic feet equals 399 second-feet for one 29-day month. 1,000,000,000 cubic feet equals 386 second-feet for one 30-day month. 1,000,000,000 cubic feet equals 373 second-feet for one 31-day month.
Seite 12 - Maximum" gives the mean flow, as determined from the rating table, 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...
Seite 16 - States gallons per second; equals 448.8 gallons per minute ; equals 646,317 gallons for one day. 1 second-foot for one year covers 1 square mile 1.131 feet or 13.572 inches deep. 1 second-foot for one year equals 31,536,000 cubic feet. 1 second-foot equals about 1 acre-inch per hour.
Seite 15 - 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 14 - 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 run-off in second-feet per square mile, and (2) those which represent the actual quantity of water, as run-off in depth in inches and acre-feet. They may be defined as follows : "Second-foot...
Seite 262 - Toward the mouth of the river the valley becomes contracted and the meadows disappear. Above Rome the Mohawk flows through a deep gorge in shale rock. From Rome eastward to Little Falls the valley is deeply filled with alluvial deposits and the flood plains on either side become submerged during freshets, thus acting to some extent as storage reservoirs. At Little Falls the river cuts through a rocky gorge, whose walls rise precipitously 500 or 600 feet.

Seite 65 - Black river at the foot of Lyons Falls. A spillway from the basin overflows into Mill creek, a tributary of Black river. Water flowing through these two channels returns to the river below the gaging station, thus passing around it. The Black River canal also flows south from Boonville, passing out of the Black river drainage and entering the summit level of the Erie canal (or Barge canal) at Rome.
Seite 191 - Falls, just below Glens Falls, it makes another abrupt turn and flows southward, continuing in this direction until it empties into New York bay. From Lake Tear-of-the-Clouds to the mouth of the river the distance by water is probably about 300 miles. The total area drained is 13,366 square miles.
