Manual of Standard Procedures for Hydrometric Surveys in British Columbia
This manual prescribes the procedures for hydrometric surveys, or the measurement and recording of water level and discharge in an open channel. The three basic measurements are discussed: gauge height (stage); and velocity and area of flow, which are required to compute discharge. The manual describes all aspects of hydrometric surveys including stream reconnaissance, site selection, station design and construction, instrumentation, gauge height measurement, discharge calculation, stage-discharge rating and discharge compilation.
Documentation of station operation and data compilation procedures is essential for verifying the quality of data for archiving; standard forms for this documentation are provided. Software for on-site computation and recording of discharge calculation is introduced.
