Olifants WMA

Chemical classification run on 2006-12-18 - 15:36:22

Program /prjws8/users/michael/aml/qatrivhtml.aml
Data file $WMSYS/wmdata/wq/MACRO061128.dat
Data selection dates 2001-01-01 to 2005-12-31
Programmer Michael Silberbauer
Institute for Water Quality Studies,
Department of Water Affairs and Forestry, Private Bag X313,
PRETORIA, South Africa 0001 - SilberbauerM@dwaf.gov.za

Note that qatrivhtml.aml includes monitoring points outside drainage region boundaries, within 500 metres of the boundaries, to allow for geographic errors. Thus, in some cases, the program may use the same monitoring point to classify two adjacent drainage regions.
Minimum number of samples used per classification = 5.
