An Integrated System for Management and Processing of Hydrogeological Data

In this paper an integrated system, named HydroGeologist was developed in Delphi 5 and runs under Windows Operating System with minimal requirements in hardware resources, in order to support the storage and analysis requirements for all hydrogeological information belonging to different public sectors. The data are stored in a distributed Oracle 8i database with embedded security and charging policies. The data search in the database is user friendly and facilitates any search queries for any field in any table of the database without any SQL knowledge. HydroGeologist can produce graphs of time series; calculate time series trend lines and statistical parameters. Geological Cross-Sections are generated on the fly from geological data and the user can change the symbols used for stones, filters or gravel packs easily. Calculation of hydrogeological parameters (T,K,S,R) from pump tests is easy, intuitive and fully parameterized. HydroGeologist can export and import its raw and processed data easily to ASCII text files and communicate with MS Office applications. HydroGeologist can also produce input files for other well-known applications such as ModFlow or Arcview.
