As a continuation and improvement of the past measuring and modelling activity, extended current measurements and joint numerical modelling were carried out in three shallow lakes in Hungary and in Finland, focusing at the near shore flow phenomena. The main goals of the investigations were to explore wind induced flow characteristics and the demands on wind input data for correct flow and related transport modelling. The systematic behaviour of the lake currents in different wind conditions at the lakes was observed with recording current meters. Comparison between the modelled and measured flow clearly showed that a spatially uniform wind stress field over the modelled lake area results in non-realistic model output. The use of corrected wind stress values, related to wind speed and surface roughness estimates, gave an improved agreement between modelled and measured currents. The realistic flow simulation is then of great importance for better estimation of water exchange and pollutant transport.
