Development of a relational data base for management and processing of hydrometric information


Duration: September 1991–May 1993

Budget: 7 200 000 DRS (about €31 943)

Commissioned by: General Secretariat of Research and Technology

Contractor: Department of Water Resources, Hydraulic and Maritime Engineering

Project director: Th. Xanthopoulos

Principal investigator: D. Koutsoyiannis

Programme: ΠΕΝΕΔ/1989

This project aims in utilising modern computer techniques, namely relational databases, for the management of hydrological data, and, to some extent, river flow data. It also aims in the development of software for data entry, testing, presentation, and processing of the data. Specifically, it includes: (1) development of specifications, and selection, purchase and installation of a relational database system; (2) database design on conceptual and physical level; (3) development of software for data entry and preliminary testing of data, and for conversion of data already available in other systems; (4) development of software for data processing (e.g. generation of hourly discharge time series from stage recorder tapes and discharge measurements); and (5) development of software for viewing and printing the raw hydrological data and their statistical characteristics, as well as standardisation of the most important database queries (e.g. mean discharge, maximum discharge, discharge correlation between different positions or basins, etc.)
