Estimating continuous monthly baseflow time series and their possible applications in the context of the ecological reserve

Abstract

The paper describes a simple technique for baseflow separation from continuous monthly streamflow records which are widely available in South Africa. The technique employs a digital filter algorithm, which has been previously used only with more detailed daily streamflow records. The example applications of the separation technique in three gauged catchments are illustrated and its possible applications in the context of groundwater and estuarine components of the ecological reserve determination are discussed.
