View on F&T portalExpected Outcome:
Open AI models that can help predict, respond to, and mitigate impacts before a disaster occurs, enabling proactive decision-making and effective disaster management effectively.
Protection of citizens from natural hazards through proactive measures, preparedness strategies, and urban resilience, planning
Project results are expected to contribute to one of the following outcomes:
- Enhanced protection of citizens from the natural hazard of flooding by facilitating proactive decision-making and effective disaster management through open AI-driven models for urban resilience strategies and planning that can help predict, respond to, and mitigate impacts before a disaster occurs.
- Improved modelling and prediction of urban and riverine flooding by expanding the capabilities of Local Digital Twins with sophisticated AI algorithms and relevant data detailing hydrological and hydraulic processes.
- Strengthened integration of diverse and essential datasets including detailed terrain, land cover, urban features, soil data, and real-time meteorological information (rainfall and temperature, river geometry, and flow) sourced from national hydrometric networks, urban drainage infrastructure, and flood protection assets. This integration aims to enhance flood analysis, simulation, and preparedness particularly in response to climate change and flood scenarios like heavy rainfall impacting nearby river basins.
The projects will leverage high-resolution climatic and meteorological models to assess extreme weather, while also drawing on relevant initiatives such as the Global Flood Awareness System and Destination Earth.
Scope:
In line with the Apply AI Strategy, proposals should develop and implement projects that advance innovative AI algorithms and models from concept to large-scale testing and validation. These solutions will be applied to the creation of Local Digital Twins for flood preparedness, enabling the simulation of flood scenarios, identification of areas at risk, and estimation of potential damage.
- Proposals should focus on the development of innovative AI algorithms that move beyond rigid functions, employing instead a dynamic set of descriptive building features derived from digital models (e.g., geometrical parameters, urban morphology, socio-economic indicators). These algorithms should be integrated with advanced, high-resolution hazard models — including hydrological and hydraulic models — tailored to the specific characteristics of the local area.
- The Local Digital Twins will enable:
- Flood damage models capable of calculating building-scale impacts, forming the basis for damage hotspot maps.
- Interactive user interfaces that allow components to be exchanged, modified, and reconfigured to estimate flood damage under various urban planning and risk management scenarios — for example, assessing the feasibility of proposed or existing constructions in flood-prone zones and recommending targeted mitigation strategies.
The scope of this topic includes a strong research and innovation component aimed at the prototyping, testing, and large-scale validation of tailored AI algorithms designed to model multiple disaster types, with a focus on operational deployment in real-world contexts. .It is recommended to prioritise the use of frugal (and local) AI as much as possible. This approach will both reduce greenhouse emissions -an indirect driver of climate-related disasters- and ensure that the tools remain functional in environments with limited connectivity.
Proposals should take into account the expertise of the European Commission's Joint Research Centre (JRC)[1], particularly its experience in developing global systems for disaster and risk management and analyse the potential uptake of the project outcomes by the Copernicus Emergency Management Service. In addition, proposals should align with for the 2025 Mission call on Local Digital Twin for urban planning, ensuring interoperability and complementarity with related European initiatives.
The project results should be modular for reuse in locations outside Europe considering constraints on deployment of AI solutions in low- and middle-income countries. Therefore, the project results shall be open source as much as possible and transferable through open platforms.

Summary of observer report:
The two independent observers were tasked by the EC services to follow the evaluation processes of call HORIZON-CL4-2026-04 with respect to their conduct, transparency, and fairness, and to provide recommendations for process improvement. This Observers’ Report consolidates their observations and recommendations. Based on the observed Consensus Meetings and Panel Meetings, the evaluation procedures for all topics were carried with transparency, efficiency, fairness, consistency, impartiality with homogenous criteria in compliance with the applicable evaluation rules for each stage of the selection exercise (Individual Evaluation, Consensus Meetings, Quality Check, Cross-reading, Panel Meeting and Final Ranking for funding). The evaluation processes were carried out in full accordance with the Horizon Europe evaluation rules and the provided Digital Europe Programme evaluation briefings. The Call with 12 topics received 312 proposals, where 5 were inadmissible, 17 ineligible and 0 withdrawn. The number of proposals per topic varied from 1 to 105. Proposals were evaluated by 218 experts, with a satisfactory gender balance (44,5% female; 55,5% male). The majority of experts were from EU Member States and a small number from associated countries. Sixteen invited experts declined due to conflict of interest or other reasons. In conclusion, the overall assessment of all submitted proposals were executed in full transparency and compliance with the Horizon Europe applicable rules in a fair and impartial manner to select the best proposals for funding according to the topics’ specifications and expected results. The observers’ conclusion is that the scientific evaluations have been carried out in a just, transparent, and unbiased manner based on the Horizon Europe evaluation rules.
We recently informed the applicants about the evaluation results for their proposals.

Evaluation results are expected to be communicated in July 2026.
If your lump sum budget contains any cost items in cost category C and/or D, please make sure to justify these items in the ‘Any comments’ sheet of the Excel detailed lump sum budget table.
The reason is that we simplified the proposal template, removing this information from Part B and bringing it closer to the relevant budget items.
Specifically, you must include justification in the ‘Any comments’ sheet if you are in any of the following situations:
- If the sum of the costs for ’travel and subsistence’, ‘equipment’, and ‘other goods, works and services’ (i.e. the purchase costs) exceeds 15% of the personnel costs for a participant. If this is the case, justify the most expensive cost item(s) up to the level that the remaining costs are below 15% of personnel costs.
- If other cost categories (e.g. internally invoiced goods and services) are used.
- If in-kind contributions are used (non-financial resources made available free of charge by third parties, which must be included as direct costs in the corresponding cost category, e.g. personnel costs or purchase costs for equipment).
