Its ultimate application computer analysis requires data in this form. technologies have thus been developed requirement. data have always in the realms of A wide range of to fulfil this In the water resources industry, the measurement of \vater levels provides the foundation from which both surface water and groundwater flOl'IS may be predicted and utilised in design. state-of-the-art technologies are based on solid state equipment developed soley for surface water applications. It lS cUJ:Tently in common use throughout the country and was adopted for trial by water Resources in the hydrographic field in the early 1980's. However, the evolution process has only commenced for the groundlllater application in Australia for which specific needs still require recognition and appropriate design. Although the Australian market is limited, there are several specific instruments available in the united states at the current time. These are not in wide use due to cost linli tations . It was decided in 1989 that the development of a system utilising the available technology should be undertaken to service the groundwater application in the organisation. The advantages foreseen included improvements in accuracy of measurement, comprehensive recording and transcription of data and also a reduction in field labour intensity. Improvements in data accessi::)ili ty would subsequently streamline the use of state-of-the-ari~ computer interpretation and modelling techniques. A project Vias thus initiated in 1990 to develop a system of digital data acquisition, retention and analysis. The three stages id'~ntified were : (1) Data Acquisition - This ,vas to be digitally recorded data using electronic componentry selected following a review
