Climate change brings along intense rainfalls and storms in the Baltic Sea region. Urban drainage systems are not capable to handle this, and therefore floods are becoming more common in the densely populated areas. Floods rise the risk of flushing untreated wastewater from urban drainage systems into the nature. This is harmful to people and environment due to the excessive amount of nutrients, hazardous substances and pathogenic microbes in wastewater. Urban areas can be prepared for floods by improved planning and self-adaptive drainage operations. NOAH project has brought together 9 towns and water utilities, 7 academic and research institutions and 2 umbrella organisations from 6 countries around the Baltic Sea to join their forces. NOAH’s approach is to create a concept for holistic planning and implement smart drainage systems in real urban environments. Holistic planning combines stormwater management with spatial planning. This is followed by development of smart drainage systems to make the existing facilities resilient to the impacts of climate change. The NOAH concept will be easily scalable to any urban area around the Baltic Sea. Implementation of the concept could cut up to half of the inflow of pollutants into the Baltic Sea. The activities will be anchored into daily practices of towns and water utilities, leading to healthier and cleaner Baltic Sea!

New Goal Based Standard issued by IMO will change the philosophy how ships are currently designed. The central element for optimal ship design will be fluid-structure interaction (FSI) model, where ship’s behaviour and structural response under hydrodynamic loads is evaluated simultaneously. The project aims to develop such combined model using two-way partitioned approach for FSI simulations. To achieve the objective, two disciplines are combined for numerical calculations: (i) computational fluid dynamics are applied for the evaluation of fluid motions and forces; and (ii) structural mechanics using coupled beam method or non-linear finite element simulations for the evaluation of dynamic response of ship hull. Focus will be on slamming loads, resistance and seakeeping characteristics, whipping response and optimal structural configuration including geometric appendages. The developments are validated with experimental tests conducted in the ship model towing tank of SCC of TTÜ.
According to the Estonian Climate Change Adaption Development Plan the frequency of extreme rainfall events in Estonia will increase 3 times by the year 2030. This will increase the load to the existing urban drainage system (UDS) causing the risk of floods and outflow of pollutants to the environment. A shift in paradigm is needed in urban runoff control to overcome these challenges. In this project a novel smart decentralized stormwater system management platform will be developed to make existing UDS controllable and thus utilize the free capacity of the system more efficiently. For that, state-of-the art solutions from environmental engineering and ICT will be integrated. Novel control modes will be coupled with UDS model and sensors equipped with low-power long-range communication technologies. The concept will be tested in lab conditions and in real UDS. The implementation of the platform enables to change the control of the existing UDS from reactive to proactive.

Interreg Central Baltic ChangeMakers project is funded under Competitive Economy priority’s specific objective More Entrepreneurial Youth. This priority aims at a balance between economic and environmental interests and to use the potential of the young generation to make the Central Baltic region more entrepreneurial and competitive in the coming years.
ChangeMakers project aims to develop sustainable thinking and innovative competence on environmental sector of Finnish (inc. Åland), Estonian, Latvian, and Swedish 15-17-year-old students.
In total, 250 students will participate and the project’s result is the creation of 50 cross-border student companies and an open access ePlatform tool “ChangeMakers”.
In Estonia, TalTech’s Mechanics of Fluids and Structures Research Group in cooperation with Innovation and business centre Mektory participate in the project. The innovative water management technology combined with ideas of circular economy are essentials for successful environmental protection. Projects broad involvement of private sector mentors and experts of sustainable environment from the university gives an excellent platform for appealing bright young minds to the environmentally oriented study programs of TalTech.

The aim of the project is to develop and test new storm water treatment solutions that are more efficient, ensure management quality and monitor of water quality near real time and enable operative response in emergency cases. In addition during the project novel water quality monitoring systems will be tested and implemented to 4 pilot sites in Estonia, Latvia and Finland.
The pollution of the Baltic Sea is a common problem, which cannot be solved by a single country. The main efforts have so far been focusing on industrial or agricultural wastewater, and pollution coming from storm water has not received sufficient attention. The use of storm water treatment solutions preventing and combating the spread of hazardous substances into the Baltic Sea through storm water is still not widespread. Available solutions are low in number, their effectiveness has not been measured and municipalities around BS do not have overview on the nature and dynamics of such substances.
During the project novel storm water treatment solutions will be implemented in Viimsi (EE), Riga (LV), Lieto and Turku (FI). Guidelines for the storm water treatment solutions will be provided for the main end-users and stakeholders (local municipalities, water utilities) to ensure the effective control and management of the units throughout their lifespan.
The lead partner of the project is Viimsi Rural Municipality Government, other partners are city of Riga, Turku University of Applied Sciences (TUAS) and Royal Institute of Technology (KTH)
