Context
The cumulative inflow of pollutants to the Danube River Basin is causing
serious environmental problems for surface and groundwater in the area.
To reduce the pollution load the Danubian Countries
established the Environmental Programme for the Danube River Basin (EPDRB,
Sofia 1991) based on the Danube Programme from the Bucharest Declaration
(1985). The goals of the EPDRB are to co-ordinate and support water
quality monitoring, data collection and assessment, and emergency response
systems. 3 sub-working groups have been thus established:
- Monitoring, Laboratory and Information Management
(MLIM)
- Accident Emergency Warning Systems (AEWS)
- Data Management (DM).
The main objective of Monitoring Working Group was
to organise the Transnational Monitoring Network (TNMN) according to
special criteria and co-ordinate the work of national focal points for the
Danube River Basin. Laboratory Management WG co-ordinated laboratory
practices by improving the inter- laboratory comparability of water
quality measurements using reliable standardised analytical methods and
co-ordinating the work of national Reference Laboratories.
In formation Management WG co-ordinated collection
of water quality data from individual countries, using the so-called Data
Exchange File Format (DEFF) and the work of national information managers
within National Information Centers. A trans-national network of water
quality monitoring stations (TNMN) was also set up to support a program
for harmonisation of data collection, processing and quality assurance.
Croatia has participated in EPDRB Programme from its
very beginning contributing to the transfer of national TNMN data for the
Danube River Basin.
Objectives
The objectives of the Croatia TNMN project are:
- to harmonise water related data processing in
different regions of Croatia
- to enable the transfer of national water related
TNMN data to the DEFF system developed for the Danube Convention
- to enable joint processing of water related data
for bilateral co-operation with Hungary, Slovenia, Bosnia and
Herzegovina
- to develop the framework for the development of a
distributed information system for management of water
quality/quantity data based on distant management practices (remote
control and networking)
- to develop integration of distributed RDBMS and
GIS data sources, and their automatic presentation on dynamic Web
pages using fast communication technologies.
Results
The results achieved up to the beginning of 1999 include the collection
and storage of TNMN data for the Drava , Sava and Danube rivers and
harmonised through the Data Exchange File Format (DEFF) developed for MLIM
activities. Data are collected quarterly and merged in the Basin-wide
Database. Transfer of regional TNMN data to the DEFF system was organised
by the authorities of these rivers. A basic digital map of the Danube
River Basin was prepared in a GIS database. Experimental static Web pages
of the Transnational Monitoring Network for the Danube River Basin in
Croatia have also been established. The development of integration of
distributed RDBMS and GIS data sources was initiated with automatic
presentation on dynamic Web pages. Testing of the remote control and
networking was initiated via 56 kb/s modems within the Zagreb area.
Further progress can be expected during 1999 in the
harmonisation of water related data, collection and storage of additional
data for bilateral co-operation with Hungary for the Mura, Drava and
Danube rivers. Experimental dynamic Web pages with the water related TNMN
information for the Danube River Basin in Croatia using integration of the
DEFF and digital map for the Danube River Basin will be achieved during
for internal 1999. In addition, other tasks will be tackled during 1999
such as the testing of the remote control and networking via ISDN
communication facilities in Zagreb, and the development of the distant
management of water related information as well as Standard Operational
Procedures for distant management of water related environmental
information.
Technical characteristics
Transfer of national data is organised through e-mail facilities using
specially structured ASCII or EXCEL files suitable for import of data into
DEFF application in PARADOX for WINDOWS. Basic statistical treatment of
the data is performed using AARDWARK for WINDOWS software (copyright by
WRC) from which the results are incorporated into classical Web pages
available on the Internet. Autodesk GIS products are used for the creation
of digital maps.
Application sharing and file transfer is performed
within the 10 Mb/s Ethernet LAN network and Remote Control and Networking
is achieved via 56 kb/s modems. In the near future, ISDN communication,
video and audio conferencing will be used for the Intranet of experts.
Data collection was organised between different
regional sources of the Danube River Basin TNMN data within Croatia.
Preprocessing of data was organised for transferring national TNMN data
into DEFF system. Further data management was performed using the DEFF
system. The data model for DEFF application was reconstructed using
reverse engineering (see E-R diagram).
The network technologies used are TCP/IP, Internet,
Remote Control & Networking using modems and tested within Zagreb
area.
Telecommunication is at present based on TCP/IP,
FTP, fax and e-mail. In the near future connection through ISDN to Remote
Access Server (RAS) will be enabled as an Intranet for experts, and audio
& video communication will be realised over H.320 and H.323 protocols.
The hardware and software requirements consist of:
- PC Pentium II/233 MHz Server, based on WINDOWS NT
4.0 Server including MS Office/Backup Office and Visual Studio. In
addition, Autodesk integration software MapGuide Server including
application software (MapGuide Author) and the corresponding MapGuide
Viewer. Remote control & networking with PC-Anywhere
- PC Pentium 233 MHz Workstation, based on Windows
97, with Autodesk GIS software (Auto CAD PC Pentium II/233 MHz
Workstation, based on Windows NT 4.0 Workstation, with PARADOX 7.0
& ORACLE 7.0 RDMS. Remote control & networking with PC-Anyware.
