The article provides information on the development of the NAVAROSO expert information system built for the needs of components active in the event of an emergency situation on the water. It provides the cross-linked data needed to quickly obtain information on the possible causes of deterioration in water quality, procedures to determine the type of pollution and estimate its spread in the watercourse.
Odra River Alarm Modul (ORAM) will be part of the NAVAROSO project. There are no results of tracer studies of the Czech part of the Odra River in the last twenty years. That´s the reason, why tracer experiment data of the Svitava River were used for analysis.
