Correlation Between Rainfall, Streamflow And Groundwater Levels For The Zachariashoek Sub‐Catchment Near Wemmershoek, Western Cape

Zachariashoek  catchment  was  one  of  the  study  areas  looking  into  the  hydrological characteristics  of winter rainfall catchments in the Western Cape. Nearly thirty years of historical data are available for the Zachariashoek area. This data include rainfall, gauge plate readings for the weirs, and water levels for the boreholes in the area. Numerous articles and reports had been written  about  the  research  done  in  the  area,  concentrating  mostly  on  the  effects  of  fire  on streamflow and vegetation. This article will look at patterns that can be observed from the data record and correlate the different data sets for the Zachariashoek sub‐catchment. It will use the data from the two weirs, three rain gauges and at least three of the boreholes that was drilled in this sub‐catchment.  The information gained from this comparison can then be used to evaluate possible future hydrological patterns and the interaction between the various components of the hydrological system.
