Methods of Water Inflow Measurement in the Bedřichov Tunnel
Original language description
In the paper, we describe methods for continual measurement of flow rates at several points of the tunnel water inflow, following the previous 5 years of manual measurement in the Bedřichov site. The aim of the measurement has to precise the time changesand spatial distribution of the inflow. Various approaches are used and further adapted or improved from their standard use. Tipping buckets are used for small flow rates (including drops) and outflow through a hole from a vessel with level measurementfor medium or changing flow rates. For total inflow rates in various parts of the tunnel, we used weirs placed in a collection canal. For the detailed distribution of total inflow along the tunnel, we used the dilution method. The methods are evaluated and compared regarding possible disturbances or inaccuracies.
