3 Short overview of the Bug river basin Countries sharing the river basin The area of the river basin in the country, km² / %: Belarus Poland Ukraine Total 39,400 km 2 10,400 (26.40%) 19,300 (48.98%) 9,700 (24.62%) 39,400 (100.00%)

4 Short overview of the river basin Belarus, Poland and Ukraine share the Bug River basin. The river s sub-basin is around 19% of the entire Vistula basin. The Bug River is 772 km long, of which 587 km are in Poland, 154 km are in Belarus. Except in its upper stretch in Ukraine (Dobrotvirsk and Sokalsk dams), the main watercourse of the Bug River is not regulated, but its tributaries are heavily regulated, in particular in Ukraine (more than 218 dams) and Poland (more than 400 dams). The reservoirs are mainly used for irrigation. Bug is connected through the Dnieper-Bug canal, rivers Muhavets and Pina with the Pripyat river, and is connected through river Narew with the basin Neman. The Western Bug has 13 tributaries stretching for 50 km including five in Ukraine, two in Belarus and six in Poland. Four of them are transboundary rivers. The Solokia and Rata flow across the territory of Poland and Ukraine while the Pulva and Lesnaya flow across Poland and Belarus. The Bug s average discharge is 50 m 3 /s at the border between Ukraine and Belarus, and 100 m 3 /s at the border between Belarus and Poland.

5 ACHIEVEMENTS OF FLOOD-WISE Preliminary Flood Risk Assessment Floods are frequent in the upper and middle parts of the river s catchment area (Ukraine) and at the border between Poland and Belarus. Significant variations in the flow regime due to melting snow in spring and low discharges in autumn greatly affect the quality of water. Last flood in the Bug river basin: 1958, 1962, 1967, 1971, 1974, 1979, 1999 The flood risk assessment in the Bug River Basin on the territory of Belarus, Poland and Ukraine bases on the interests of governmental and regional management structures, water uses, households to appropriate precaution measures against flooding within the bounds of possibility and reasonability. Possible criteria for the determination of significant areas are: flood level and flow rate; number of affected inhabitants and building; amount of expected damage; important infrastructure; flood prevention measures.

6 ACHIEVEMENTS OF FLOOD-WISE Flood hazard maps and flood risk maps Common suggestions: all Bug countries are using same system of terrain heights (Baltic System); to prepare FHMs and FRMs for pilot Bug river basin district area for scenarios 1% (once per 100 years), 5% (once per 20 years); 10% (once per 10 years); to use hydraulic method for modeling, GIS modeling with using public data sets and prepared hydrological and morphological data; to take into account existing good practices regarding methodology and technology of the preparation of an Flood Risk Maps and Flood Hazard Maps i.e. LAWA method etc. Problems: not so good quality of maps

7 ACHIEVEMENTS OF FLOOD-WISE Flood hazard maps and flood risk maps Important actions Morphometric and hydrology data exchange between Central Research Institute for Complex Use of Water Resources (Minsk, Belarus), District Office of Włodawa (Poland) and Volyn Regional Board of Water Management (Western Bug Basin Water Department, Lutsk, Ukraine) during August-December 2011; Creation of the mathematical model of pilot Bug river district and hydraulic modeling (1D hydrodynamic model based on Sean Venan equations); Creation of the Digital Elevation Model (DEM) of the territory of pilot Bug river district. Starting from all the available information, cross-border flood hazard maps and flood risk maps were created. Stakeholders in the Bug countries have planned to use the maps in their practical work within the framework of flood risk management.

8 ACHIEVEMENTS OF FLOOD-WISE Flood hazard maps and flood risk maps Digital Elevation Model (DEM) for the pilot transboundary district (Poland Ukraine Belarus) was developed with using of the next information: STRM-model (Shuttle Radar Topography Mission conducted in 2000 to obtain elevation data for most of the world. It is the current dataset of choice for digital elevation model data (DEM) since it has a fairly high resolution - about 90 meters for the Bug River Basin, has near-global coverage, and is released into the public domain); Detailed maps of Wlodawa scales of 1: and 1:25 000; Map of the entire Bug River Basin of 1: (map from the Soviet time); Map of the entire Bug River Basin of 1: (Poland map); Google maps.

9 ACHIEVEMENTS OF FLOOD-WISE Flood hazard maps and flood risk maps For the transboundary area of the Bug, common flood hazard maps were created, using data from Poland, Belarus and Ukraine. The flood hazard maps refer to various probabilities (1%, 5% and 10%).

10 A more detailed flood hazard map was made for the town of Wlodawa ACHIEVEMENTS OF FLOOD-WISE Flood hazard maps and flood risk maps

11 ACHIEVEMENTS OF FLOOD-WISE Flood risk management plan Solutions found A start on trilateral flood risk management planning for the Bug During FLOOD-WISE, all three Bug countries (Poland, Belarus, Ukraine) cooperated for the first time in flood risk management. The partners exchanged morphological and hydrological information, exchanged good practices and implemented experiences from other partners. Starting from all the available information, cross-border flood hazard maps and flood risk maps were created and a flood risk management plan was developed. Stakeholders in the Bug countries have planned to use both the maps and the FRMP in their practical work within the framework of flood risk management.

12 Objectives and measures of the FRMP (combined for all Bug-countries but based on the Polish example in general) Prevention Goals: The analysis of the reasons and possibilities of flood occurrence; Assessment of flood risks depending on reasons; Water resources management including flood risks decreasing. Measures: Determination of inundation zones depending from the levels of floods; Development of water resources management plans of different levels (regional, state) with using river basin approach; (No) permission from Local Administration for new building activities in inundation zones of river Bug on distance to 500 m from river bank (no any activities to 30 m from bank, trees planting from 30 to 500 m from bank is allowed only)/ To take into account of inundation zones of river Bug with elevations about 1% of flood-probability in cases of permission from Regional Administration for new building activities in inundation zones (planned measures in Belarus); Optimization of land use.

13 Objectives and measures of the FRMP (combined for all Bug-countries but based mostly on the Polish example) Protection Goals: Maximum possible decrease of flood damages Measures: Existing dikes improvement for protection against floods; New dikes disposal for flooded urbanized and rural areas; Building, modernization, maintenance service and exploiting of other flood protection hydraulic structures; Watercourses cleaning; Bank protection. 1% of probability safety level plus 1 m behind primary dikes along river Bug (Belarus); Preparedness Goals: Reduction of flood damage and casualties by actions taken before possible floods Measures: Assessment of meteorological and hydrological situation; Flood Risk Assessment depending from current hydrological situation; Maintenance in readiness all required services and technical equipment; Development of the Detailed Action Plan during floods including communication and measures on evacuation including definition of places for evacuated inhabitants; Dike monitoring before floods; Communication and information about possible floods.

14 Objectives and measures of the FRMP (combined for all Bug-countries but based mostly on the Polish example) Emergency response Goals: Adequate response depending from the level of flood; Reduction of flood damage and casualties during a flood. Measures: Early notification; Dike monitoring during floods; Protection measures during floods; Acquaintance of all participants of measures with their tasks and action plan; Accurate differentiation of duties in case of floods ; Evacuation; Information of population with actions for decrease of flood consequences and flood damages; Communication and information about the flood The medical and humanitarian help to the population and life-savers. Recovery Goals: Recovery from flood damage after a flood. Measures: Reconstruction measures and their financing

15 Issues addressed to the future (possible actions): No measures that considerably increase the transboundary impact of flood risk in the Bug River Basin due to requirements of the Convention on Protection and Use of Transboundary Watercourses and International Lakes/ Helsinki Convention because of all Bug countries ratified this Convention (exceptions possible if all parties on the state level agreed: origin, affected and concerned due to ESPOO Convention classification of involved parties); Objectives of flood risk management as well as of the environmental objectives set by EU Water Framework Directive; Integrative measures (water management and soil, spatial planning, land use optimization and nature conservation); Possible implementation of sustainable land use practices, improvement of water retention, as well as the controlled flooding of certain areas; Possible Implementation of EU-experience for different safety levels along the river Bug, depending on land use including built areas (1:100), agriculture (1:25), grassland (1:10), Nature (including the floodplain near the river Bug) - no safety level;

16 Possible actions: Possible implementation of measures reducing possible negative impact of engineering activities (i.e. existing dikes improvement and new dikes disposal, watercourses cleaning and bank protection) on environment; Hydrological Information exchange between countries of river Bug on regular bas and in on time regime in case of extreme flood; To use EU-experience in part of funding for recovery after a flood and compensates measures; Development of the Bug River Basin Water Resources Management Plan for the entire river basin (Poland-Belarus- Ukraine); Implementation of measures to further improvement of the water regime in river Bug (in combination with nature development and other goals) for regional development and adaptation to effects of climate change.

17 ACHIEVEMENTS OF FLOOD-WISE Using of good practices in flood mapping for the river Bug Implementation of flood forecasting models for the Styr River (Pripyat River Basin) Within the framework of the Project Flood Monitoring and Forecast in Pripyat River Basin (NATO Science for Peace and Security Programme and Environmental and Security Initiative), Ukrainian, Belarusian and Slovak partners implemented connected flood forecasting models for the Ukrainian and Belarusian parts of the Styr River. The organizations involved in the project were: Central Research Institute for Complex Use of Water Resources (Belarus); Ukrainian Center on Environmental and Water Projects of Academy of Technology and Sciences (UCEWP); Ukrainian Hydrometeorological Institute (UHMI); Slovak Hydrometeorological Institute (SHMU).

21 Conclusion and issues addressed to the future The countries of the Bug River Basin (Poland, Belarus and Ukraine) have their own programs on flood protection measures which mostly devotes to engineering dikes construction to protect some settlements from floods. Since existing programs and plans do not (yet) take into consideration transboundary impact of own measures and activities. Therefore cross border flood management plans should be developed. Cross border contacts and cross border information exchange in times of floods, focused on calamity management and early warning will be important and useful. Strengthening of cross border contacts and the forming of an trilateral Bug River Basin Committee would be a good suggestion for increasing efficiency of Flood Risk Management in the Bug River Basin, including improvement of exchange of data, insight in each other problems and benefits, insight in the right partners who are responsible for the various goals and tasks

22 Conclusion and issues addressed to the future To take into account Recommendation for the Bug-countries governments from FLOOD-WISE Project in real practice of water resources management including flood management in the Bug River Basin. To propose international projects on more detail specification of the Flood Risk Maps and Flood Risk Management Plan for the entire transboundary river Bug district based on more detail cartographic information and common hydrological and hydraulic model; To propose international projects on the development of prototype of Early Warning System for the river Bug with installation of the Automatic Hydrometeorological Stations (AHS) on river Bug (as similar on Tisza river - Hungary/Romania/Ukraine).
