Weir flow measurement is a fundamental hydraulic technique used to estimate channel discharge by relating the upstream water level (stage) to the flow rate. The stage-discharge relationship, central ...

The current standards recommend measuring water discharge with vented thin-plate weirs. The ventilation of full-width, thin-plate weirs during discharge hydrograph measurement still poses a problem.

Present the key results and describe any major deviations from the printed procedures and why you did them. Report flows in cfs, head in ft, & time in seconds. You do not need to turn in the lab ...

IN hydraulic problems the use of the principle of extremum has produced results in good agreement with the results of experiments for some cases in which streamlines are nearly rectilinear and the ...
