Geohydrology data model design : South African boreholes

[摘要] Since mechanised borehole drilling began in South Africa in the late 1800s, over1 100 000 boreholes have been drilled. As the country's growing population and theperceived impacts of climate change increase pressure on water surface supplies,attention is turning to groundwater to meet the shortfall in water supply. This willmean even more drilling will take place.Until the introduction of the Standard Descriptors for Boreholes, published in 2003,South Africa has not had a set of guidelines for borehole information capture. Thisdocument provides a detailed description of the basic information requirementsneeded to describe and characterise the process of drilling, constructing, developing,managing and monitoring a borehole. However, this document stands alone as aspecification with little or no implementation or interpretation to date.Following the development and publishing of the ArcHydro data model for waterresource management by the CRWR based at the University of Texas at Austin, therehas been a great deal of interest in object-oriented data modelling for natural resourcedata management.This thesis describes the utilisation of an object oriented data modelling approachusing UML CASE tools to design a data model for South African Boreholes, based onthe Standard Descriptors for Boreholes. The data model was converted to ageodatabase schema and implemented in ArcGIS.
