On 1 - 2 April 2004 took place in Budapest, at the HMS and VITUKI institutes, the 2nd Co-Directors Meeting of the NATO SfP Project 978016, with the participation of the project Co-directors, included representatives of the END-users, HYDRO and SAT-GIS Groups. Prof. Brakenridge was unable to attend the meeting but he was replaced by his assistant, Dr. Sebastien Caquard, which is fully involved in the project. Also, Dr. Jiri Marsalek, the project consultant attended the meeting.
During the meeting was analyzed the current status of the project, and were presented the results of the works performed in Romania, Hungary and USA.
The SAT- GIS Group presented and discussed different methods and algorithms of satellite image processing and analysis for detection of surface water and water delineation using especially ASTER and MODIS data. Special attention was given to the problems related with the clouds/shodows mask and image geo-referencing.
The SAT- GIS Group presented and discussed the methodology for the achievement of the land cover/land use for the vulnerable area, using ASTER data with 15 m resolution. Because the region is not fully covered with ASTER images, was decided to use also LANDSAT-ETM data.
It was decided to organize a short working stage in NIMH Bucharest, in the first week of June 2004, with the participation of Ms. Elaine Anderson, Ms. Judit Kerényi and Maria Putsay. The main items of this meeting will be:
- Developing new methods/procedures for evaluation and cartography of the
flood hazard using satellite data;
- Design and installation of the dedicated sub-system based
on remote sensing and GIS for the transboundary area.
An important part of the meeting was devoted to the dedicated sub-system based on remote sensing and GIS technology to improve flood management and aid the development of flood mitigation programs in the Romanian - Hungarian transboundary test-area. It was mentioned some important functions of this sub-system, like updating of the Information (temporal modification), data restoring, including the elaboration of thematic documents, generation of value-added Information (complex indices for flood prevention, risk maps). Also it was emphasized the necessity to elaborate standardized products which will be distributed via the central network Internet interface. Such a very effective management and data storage via distributed databases enables a fast and sustainable access to the Information required for flood monitoring purposes and for the generation of statistically significant large data records. The proposed structure guarantees effective data management and exchange facilities using high tech and up-to-date Information technology tools.
Relating with the GIS database which has to be developed in the study area it was decided to include the following Info-layers:
- sub-basin and basin limits;
- land topography (organized in DEM);
- hydrographic network, dikes and canals network and other hydrological
- communication ways network (roads, railways);
- meteorological stations network, rain-gauging network, hydrometric stations
- land cover/land use, updated from satellite images.
The GIS will be in a UTM projection and the elevation reference will be the Baltic Sea.
An important matter was dealing with the precise DEM. There exist 3 technical possibilities: LIDAR, radar interferometry, using topographic maps and ground elevation data. The LIDAR approach is costly prohibitive and for the radar interferometry was decided to elaborate a formal request (with the area, elevation resolution, etc) to find some specialized companies in Europe, USA or Canada and to ask for a price evaluation. In the Romanian vulnerable area the DEM construction already started using the topographic maps 1:5,000 and 1:10,000); the precision will be less than 1 m.
It was decided that the Hungarian part will establish in short time a GIS Team and an expert GIS meeting will be organized in the future 2 months in Oradea or Guyla.
The Hydro Group discussed about the rainfall-runoff flood forecasting model and the hydraulical model which will be used in the project. The Romanian part proposed the hydrological forecasting VIDRA model, which has the ability to take into account the influence of the tributaries and which will permit an increasing of the the lead-time of the forecast. The Hungarian part proposed the hydraulical (lag & route) HEC-RAS model. It was decided that this model will be applied by the Hungarian HYDRO Group in the Hungarian study area and will be extended to a part of the Romanian Crisul Alb and Crisul Negru Basin, situated near the border. In this respect the Romanian partners will provide some topographic profiles and hydrological data, necessaries for the model input parameters. The details will be arranged in the near future between the Romanian and Hungarian HYDRO members.
It was mention the necessity to permanent consider the Criteria of success of the project. In this respect an important task is to involve young people in the objective Achievements of the project, to improve the visibility of the project by elaboration and presentation of related scientific papers at international Conference and Symposia, to contribute to the up-dating of the project web page, etc.
Dr. Marsalek proposed the organization of a NATO Workshop in 2005, Oradea - Romania, with the support of the NATO funds (other than exists in the project) and in this respect the elaboration and submission of the proposal. (deadline September 2004). It was established a working team in charge with this task which include: Dr. Marsalek, Dr. Stancalie, Mr. Tentis - Director of the Crisuri River Authority, and Dr. Gabor Balint from VITUKI, Budapest.
