Stage measurement at gaging stations
Thomas J. Buchanan, William Philip Somers
1968, Techniques of Water-Resources Investigations 03-A7
Continuous measurements of stream stage are used in determining records of stream discharge. In addition a record of stream stage is useful in itself, as in designing structures affected by stream elevation or in planning the use of flood plains. This report describes instruments and structures commonly used in obtaining...
