Seite 11 - ... 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 10 - For each regular giiging station are given, as far as available, the following data : 1. Description of station. 2. List of discharge measurements. 3. Gage-height table. 4.

The bed of the stream is rocky and rough, and makes soundings uncertain. The bed is permanent and the flow is rapid. Discharge measurements are made from the sidewalk on...

The discharge through the turbines is taken from diagrams expressing the flow as a function of the working head and number of wheel-hours run. In the winter of 1896—1897, a flood spillway was cut around the south end of the dam, over which the water begins to flow whenever it reaches the level of the crest of the flash-boards. The...
Seite 290 - ... excessive floods. Dikes have been erected in the cities of Elmira and Corning for protection. One of the highest recorded freshets in the stream occurred June 1, 1889. It was preceded by phenomenal rainfall, aggregating several inches in a few hours during the night of May 31. The discharge at this time has been estimated at 67 secondfeet per square mile from 2,055 square miles, or 138,000 secondfeet.0 CHEMUNG RIVEB AT CHEMUNG, IST.
