Integrated System of Forecasting Flood of European Level in Ukraine

In Ukraine, the creation of an Integrated Nationwide Forecasting System for Flood on the Prut and Siret Rivers has been started. Considering that these rivers are transboundary ones, the consequences of their spill, except for Ukraine, are manifested in the territories of neighboring states—Moldova and Romania. Due to the combined efforts of these countries and the financial support of the European Union, Ukraine is implementing a comprehensive flood monitoring system to minimize annual human losses and property damage from floods in the basins of these rivers.   Kyiv, January 23, 2015 In the summer of 2014, the Bancomzvjazok Company won the international tender for the creation of a geoinformation system and the modeling of possible risks and dangers maps, funded by the European Union within the framework of the East Avert Romanian-Moldovan-Ukrainian Project. The customer of the works was one of the partners of the East Avert Project—the Dniester-Prut Basin Water Resource Board (State Agency of Water Resources of Ukraine). Work on the project has begun in August 2014. In order to create this unique integrated system, the leading Ukrainian experts in the field of geoinformation systems and hydrological modeling have been involved, and advanced technologies have been used.   As part of a large-scale international project, the following works are performed:
  • building a network of automatic gauging stations;
  • creation of a detailed digital map of the area with the use of aerophotography;
  • modeling maps of possible risks and hazards in the Prut and Siret river basins;
  • creation of a geoinformation system (GIS) for the collection, storage, analysis, and graphical visualization of data on territorial facilities.
  “The project will combine a new system of subsystems for automated measurement and data collection of river state monitoring, new digital maps of river basins (GIS subsystem), and modern forecast computer models for predicting the levels of possible flooding during high floods on the Prut and Siret Rivers. The challenge for the Ukrainian side is the need to create a forecast system that, according to its technical level, would be in line with the forecasting system for the Romanian part of the basins of these rivers that meets modern European scientific standards, within the framework of creating a transboundary forecast system. In the project, this task is carried out by Ukrainian specialists who are developing a new numerical detailed forecast model for precipitation for the Prut and Siret river basins. Precipitation forecast data will be used by a modern computerized forecasting system for water levels in rivers and a subsystem for mapping GIS-based flood zones,” Mark Zhelezniak, Head of the Department of Mathematical Modeling of the Environment of the Institute for Problems of Mathematical Machines and Systems of the National Academy of Sciences of Ukraine, Laureate of the State Prize of Ukraine in Science and Technology, Professor of the Institute of Radioecology of the University of Fukushima (Japan), says.   According to him, such a system will not only allow forecasting of flood zones in time and with high accuracy, but it can also be used to support the design of the most effective engineering flood control measures.   The detailed technical scheme of the new system, which was demonstrated by representatives of the Bancomzvjazok Company, has shown where in the basins of Prut and Siret the automated systems will be installed for the first time to collect data on water levels and precipitation that will enter the system every few hours and be transmitted in real time for processing. It is planned to create a system of collective access to information on the state of flood prevention activities, risk zones, development and possible consequences of flood situations for experts, the Basin Water Resource Board, the Water Management Department, interested ministries, departments, and the population based on the geoportal.   The introduction of an integrated flood forecasting system will allow solving the following tasks:
  • Obtaining accurate and timely information about water levels from automatic gauging stations to assess the current state of the hydrological situation and forecasting.
  • Identification of high-risk flood areas to optimize the cost of precautions.
  • Establishment of a system for informing decision-makers and the public about the level of danger and hazardous areas that may arise during flood situations.
  The launch of the integrated national flood control system on the Prut and Siret Rivers and the training of the personnel of the dispatch center of the system is planned to be implemented by the end of November this year.
