Over the last few years, countries in Central and Eastern Europe (CEE) have been frequently impacted by extreme flooding that causes damage to historic cities and forces mass evacuations in low-lying areas. Flood mapping, management, protection, and warning systems are the key to addressing these growing flood challenges.

In Poland, Hungary, Slovakia and Romania – where we have on-going projects – flood forecasting is especially important. MIKE by DHI and MIKE CUSTOMISED by DHI technologies are being applied to conduct in-depth studies to develop solutions. In Poland, for example, we recently localised an applied flood forecasting system, focusing on the city of Tarnow and three nearby locations along the 180 km long Biala Tarnowska River.

‘To meet urban water infrastructure systems standards and demands set by the government, we must understand the huge impact on long term performance and further development,’ says Tomas Metelka, Head of Innovation and Software Sales, DHI CEE. ‘Network rehabilitation planning is vital in order to optimise investments and reduce operational costs as well as reduce the risks associated with urban water construction and services.’

Water scarcity is a problem in many parts of the world. In Bulgaria, for example, many villages suffer from a lack of drinking water during the hot summer months. We’re doing what we can to help alleviate these problems. Recently, we were invited to analyse the impact of climate change on water scarcity in the Western region of the country.

For a number of cities in the CEE region, urban storm water management studies that assess the complex current status of water management, including the risk of flooding, are essential. Read our Group newsletter to find out more about our projects in this and other areas as well as our commitment to solving various water-related issues in the CEE region.

Contributing to the Danube Atlas
In recent years, the number of industrial and urban areas near the Danube River has increased, potentially raising damage costs during severe flooding. To help improve flood management, eight countries participated in the Danube Floodrisk project, where hydrodynamic modelling for a 172 km stretch of the Danube River was conducted along with numerical simulations of various dike breach scenarios. The results helped to determine the most cost-effective measures in reducing flood risk in the area.
Improving water quality in Bulgaria
The Bulgarian Government implemented a large Regional Municipal Infrastructure Development Project in 2011-2013, aiming to improve water supply in compliance with the National Environmental Strategy of Bulgaria. To achieve this, they needed regional Master Plans for water supply and sewerage systems in designated territories in the country. At the end of the project, 19 regional water supply Master Plans, along with short-, medium- and long-term investment programmes were successfully provided.
Alleviating floods in the Morava River Basin
Following a devastating flood in the Morava catchment in 1997 - with estimated reconstruction costs of USD 1.5-3 billion - stakeholders needed to pick the best mitigation plan that reflected a good balance between efficiency and investment costs. This was where flood damage assessment tools came into play, providing cost-benefit analyses and Environment Impact Assessments. The eventual solution formed the basis for negotiations between the Government of the Czech Republic and the European Investment Bank.
Managing Sokolov’s water network in a smarter way
Sokolov Water Company initiated a pilot project to optimise their existing water operations. A hydraulic model of the regional water network - linked to the supervisory control and data acquisition (SCADA) system - was set up to analyse network behaviour in real-time. Users could now create thematic maps, monitor hydraulic quantities and easily create unlimited output of results. This system is currently being progressively implemented as a standard operator's tool.
Integrated hydraulic modelling to assess flood risk in the Skawina Economic Zone
During heavy rainfall, Rzepnik River experiences massive currents which can potentially result in heavy flooding. With imminent development plans along the river, Skawina Water Company needed to ensure that these activities would not increase flood risk in the catchment. Integrated modelling allowed us to verify drainage performance, helped improve the storm water drainage system and at the same time, identified solutions to protect the area from flooding.
A sustainable water network for Szeged, Hungary
The city of Szeged has a large network of older pipes in dire need of replacement to avoid serious leakage problems. Due to wear and tear, these pipes - constructed during the 1960s and 1970s and made from asbestos cement - are now in a critical state. The ongoing solution allowed Szeged Water Utility to create multiple network reconstruction scenarios and helped identify the most critical pipes for restoration.
Safe and efficient inland navigation on the Danube River
Good navigational maps are invaluable tools for vessel skippers on inland waterways like the Danube River – especially on complex stretches. A forecasting system that provides real-time information – enabling skippers to automatically update their navigational maps – is vital for ensuring safety and efficient transportation.

/ THE ACADEMY: Enhance your knowledge

THE ACADEMY by DHI provides training relevant to water environments all over the world, with upcoming courses and knowledge sharing events in Poland, Romania and the Czech Republic.
Available courses include:

  • Flood forecasting and early warning systems—in Krakow, Poland, 19-20 November 2014. More information here.
  • MIKE URBAN workshop – in Romania, December 2014. Contact us for more information.
  • A seminar on MIKE CUSTOMISED by DHI – in the Czech Republic, first half of 2015.
    The seminar will present tools to support decision-making in water management. It will first focus on decision support systems for urban infrastructure planning and then discuss early warning systems for flooding. Send us a mail for more information.

Training in software such as MIKE 11, MIKE 21 and MIKE SHE to universities and research institutions worldwide is also available. Click here to learn more.
