Page 4 - Run-off 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. "Acre-foot...
Page 9 - 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...

Page 11 - 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.
