Lake delta morphology is determined by fluvial input, waves, lake currents, lake-level fluctuations and lake-basin topography. The current-dominated Versoix delta (Petit-Lac of Lake Geneva, Switzerland), has been studied in order to determine the role of wind-driven currents on transport and sedimentation of suspensions. Research included the study of sediment distribution in the lake basin, of currents due to wind forcing and modelling of lateral particle transport of suspended matter by lake currents.
