Soil particles from rainfall flow into reservoir and give lots of influence in water quality because the Even though techniques related with computer and communications are growing rapidly, it is true that efforts for hydrological survey and the management of its results have not been made enough to make use of the state-of-the-art technologies. Among the water-related techniques, measurement of river discharge is the most important one because these data are basic to almost every field of the hydrological science. In this research, a large-scale particle image velocimetry (LSPIV) unit has been designed and constructed to measure river discharge effectively In field conditions. Measured data using this unit is compared with the results recorded by the microwave water surface current meter (MWSCM) at the same location. The purpose of this research is to propagate the feasibility of using the MWSCM for river discharge velocimetry.
