Comparison and Calibration of Different Discharge Measurement Methods

Discharge is one of the most important physical values in the fields of water management but unfortunately not directly measurable. Therefore different methods have been investigated to measure this value. This diploma thesis deals with the calibration and the comparison of different discharge measurement methods and their reliability in practice. Therefore comparative investigations and calibrations were carried at a natural stream in Western Styria and in the sewer system of Graz near a combined sewer overflow by using different reference methods.
