N2  - The aim of this studyis to predict low flows 14 days in advance using a data-driven model. First, weapply correlation analysis to select appropriate temporal scales ofpre-selected inputs that are precipitation, potential evapotranspiration,discharge, groundwater, snow height and lake levels. The forecasted rainfall hasalso been used as model input to forecast low flows in the River Rhine atLobith. The correlation analysis analysis between low flows and basinindicators show stronger correlations for the Alpine sub-basins than therainfed sub-basins. The Middle and Lower Rhine are downstream channel areas andthey do not contribute to the discharge. Therefore, they are excluded from theentire analysis. The low flow predictions for the Alpine sub-basins and theMosel are reasonable during the validation period, whereas the ANN for Lobithshows low performance for a different test period. The results for the trainingand the validation period are more encouraging than the test period for Lobith,i.e. Nash-Sutcliffe (NS) efficiency of 0.75 and 0.73 respectively.
