Wet Weather Hydrological Gauging Cards

Gaugings cards are measurements of stream/river flow. The majority of these flow measurements have been undertaken using mechanical current meters. Increasingly flow measurements are undertaken using acoustic Doppler current profilers (ADCP’s). A small proportion of these measurements have been undertaken using other mechanisms such as visual estimates, slope/area, salt dilution, contracted opening, weir and culvert formulas, and a number of less common methods of flow determination.

In inclement weather, Wet  Weather forms are used.  On return to the office, the information from these forms is transferred to the Gauging cards for each site.
