Volume measurement discharge in surface runoff for refine continuous measurement

The thesis is divided into theoretical and practical part. The theoretical part includes issues associated with runoff and discharge, methods for discharge measurement and measurements of uncertainties. The practical part of the thesis describes a specific process flow measurement in Kopaninský and Jenínský stream. There is a familiarization with the water flow velocity measurement and comparison methods of volume measurement discharge with continuous measurement. The results of the practical part served to refine the rainfall-runoff processes in research catchment areas. Refined values of the flow rate were used as input data for the calculation of the runoff coefficient and for quantifying the losses of nutrients from the catchment areas. Calculation of the runoff coefficient and nutrient losses were compared for the original and the revised equation discharge curve. Volume measurement discharge has shown that the different conditions above measurement weir during continuous monitoring lead to the uncertainties of measurement. That´s why one has to approach to each flowmeasurement individually and consider the situation in a particular installation
