Streamflow concentration

This dataset contains periods of highest streamflows and streamflow concentration in South Africa. Periods of high streamflows are defined as the 3 consecutive months which have the highest cumulative median streamflows at the outflow point of a Quaternary Catchment (QC). Streamflow concentration is defined as the percentage of mean annual flow that is made up of the highest 3 month cumulative streamflow in a QC (including upstream contributions), with a low percentage indicative of a spread of streamflow and vice-versa. Distribution patterns of the 3 consecutive month period over SA of highest streamflows are the December (i.e. November, December, January).
