Although there are current initiatives to standardise this in Australia, the trialled logging systems have individually developed forma.ts. 6.2.1 Gene,rated Data Examples of data output are shovm in Figures 6.1, 6.2, and 6.3 with features of each annotated. 6.2.2 Existing Data Exist.ing data is tabulated in time series form. Test pumping data generally consists of ,<later level and flow rate measurements taken simultaneously on a time scale suited to logarithmic plotting. water conductivity 1 pH and temperature are measured intermittently. 6.3 Data CatalClguing All procE,ssed data systematic dat,a storage needs to be catalogued to enable and to enable easy and effective retrieval. It is expected that the 'HYDSYS' system will require the data to be formatted specifically to enable data retrieval using this system. However, a general system of cataloguing is still required for data housed in a separate library. 6.3.1 Genorated Data The data loggers trial led each have provision for labelling and identification of the data set contained within it. However, the format of this is dependent on the logging system. The proposed system described in Appendix E attempts
