Seite 10 - CONVENIENT EQUIVALENTS The following is a list of convenient equivalents for use in hydraulic computations: Table for converting discharge In second-feet per square mile into run-off in depth in inches over the area.
Seite 11 - ... deep. 1 second-foot for one 28-day month covers 1 square mile 1.041 inches deep. 1 second-foot for one 29-day month covers 1 square mile 1.079 inches deep. 1 second-foot for one 30-day month covers 1 square mile 1.116 inches deep. 1 second-foot for one 31-day month covers 1 square mile 1.153 inches deep. 1 second-foot for one day equals 1.983 acre-feet.
Seite 12 - At most stations the gage is read in the morning and in the evening. The discharge measurements and gage heights are the base data from which the other tables are computed. In cases of extensive development it is expected that engineers will use these original data in making their calculations, as the computations made by the Survey are based on the data available at the time they are made and should be reviewed, and, if necessary, revised when additional data are available.
Seite 11 - British imperial gallons per second. 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 11 - ... equals 31,536,000 cubic feet. 1 second-foot equals about 1 acre-inch per hour. 1 second-foot for one day covers 1 square mile 0.03719 inch deep.
Seite 11 - Table of estimated monthly and yearly discharges and run-off, based upon all the facts obtained to date. The descriptions of stations give such general information about the locality and equipment as would enable the reader to find and use the station, and...
Seite 11 - ... square mile equals 2.59 square kilometers. 1 cubic foot equals 0.0283 cubic meter. 1 cubic foot of water weighs 62.5 pounds. 1 cubic meter per minute equals 0.5886 second-foot. 1 horsepower equals 550 foot-pounds per second. 1 horsepower equals 76.0 kilogram-meters per second. 1 horsepower equals 746 watts. 1 horsepower equals 1 second-foot falling 8.80 feet.
Seite 12 - 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 12 - In the table of monthly discharge the column headed "Maximum" gives the mean flow 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.
Seite 10 - means the depth of water in inches that would have covered the drainage area, uniformly distributed, if all the water could have accumulated on the surface. This quantity is used for comparing run-off with rainfall, which quantity is usually given in depth in inches.
