Seite 170 - 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...
Seite 174 - 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 173 - ... or. in ponds, lakes, and swamps, and this stored water passes off in the streams during the spring break-up ; at the end of September, on the other hand, the only stored water available for run-off is possibly a small quantity in the ground; therefore the runoff for a year beginning October 1 is practically all derived from precipitation within that year.
Seite 174 - ACCURACY OF FIELD DATA AND COMPUTED RESULTS The accuracy of streamflow data depends primarily on (1) the stability of the stage-discharge relation or, if the control is unstable, the frequency of discharge measurements, and (2) the accuracy of observations of stage, measurements of discharge, and interpretation of records. The station description states the degree of accuracy of the records.

Seite 164 - Run-off in inches" is the depth to which an area would be covered if all the water flowing from it in a given period were 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," equivalent to 43,560 cubic feet, is the quantity required to •cover an acre to the depth of 1 foot.
Seite 164 - Cubic feet per second per square mile (cfsm) is the average number of cubic feet of water flowing per second from each square mile of area drained, assuming that the runoff is distributed uniformly in time and area. Runoff in inches (in.
