Abstract

Contemporary open source JAVA technologies implemented within the EURANOS project for the cross-platform re-engineering of the decision support system RODOS (JRODOS) were used also to redesign the Hydrological Dispersion Module (HDM) of this system. JHDM – the hydrological model chain of JRODOS contains models to simulate the radionuclide transport in the system “atmospheric fallout on watershed – river net” and calculate the doses via aquatic pathways. JHDM used for this purpose a limited number of the input parameters to characterize the hydrological properties of the catchment/river network of interest. The pilot implementation of JHDM for the Vistula river basin carried out by POLATOM and supported by the national hydrological institute, demonstrated good perspectives of the approach used in JHDM for the decision support in cases of accidental contamination of water systems. Particular needs for further improvements of the JHDM software system have been identified.
