High-Resolution Pluvial Flood Modelling
Understand heavy rainfall risk precisely. Plan protection measures effectively.
Bespoke flood simulations down to 1 m resolution, for current and future climate-intensified heavy rainfall events.
Sustainaccount combines terrain, 3D building models, soil characteristics and climate projections to create customised pluvial flood simulations. We model flood depths, flow paths and flow velocities, and can incorporate planned protection measures directly into the analysis.
High-resolution modelling for site-specific flood decisions
Spatial resolution down to 1 metre
Pluvial flood risk is often determined at building and property level. High-resolution modelling reveals critical features such as access roads, loading ramps, building edges, depressions and local flow paths.
Buildings, terrain and soil included
The simulation reflects the actual spatial environment. 3D buildings, terrain and soil characteristics influence where water flows and accumulates.
Future climate conditions
The model can incorporate climate-intensified heavy rainfall events, allowing users to assess how today’s exposure may change under future climate conditions.
Protection measures can be simulated
Planned public or private flood protection measures can be incorporated directly into the model. This allows a simple comparison, so the effectiveness of a measure can be assessed before implementation.
From flood hazard to climate resilience
Pluvial flood modelling integrates directly into Sustainaccount’s Climate Resilience Suite.
Hazard
Where can flooding occur and at what intensity?
Vulnerability
What does the flooding mean for the specific building, infrastructure or process?
Financial risk
What damage, losses or financial exposure could result?
Adaptation
Which measures reduce the risk and what residual risk remains?
Who benefits?
Municipalities and Public Authorities
For pluvial flood management, climate adaptation planning, neighbourhood development and the assessment of public protection measures.
Planners and Engineering Firms
For testing planning alternatives, terrain modifications, retention solutions and resilient site design.
Developers and Building Owners
To identify flood risks early in the planning process and avoid expensive retrofits later.
Property Owners and Asset Managers
For existing-asset assessments, CAPEX planning, due diligence and adaptation prioritisation.
Investors, Banks and Insurers
For more detailed physical risk assessment where conventional portfolio screening or hazard scores are not sufficient.
Auditors and Certifiers
As technical evidence for climate risk and vulnerability assessments, for example in the context of the EU Taxonomy, DGNB or BREEAM.
Industrial and Infrastructure Operators
For identifying critical areas across production, logistics, energy and infrastructure sites.
One model. Different decisions
Existing assets
Where does water accumulate today?
Future climate
How does more intense rainfall change the situation?
Development
How do buildings or terrain modifications affect water flows?
Adaptation
How effective is a planned protection measure?
Asset risk
What are the consequences for buildings and operations?
Turn heavy rainfall risk into a decision.
Whether you are assessing a single building, corporate facility, industrial site, development project or municipal area, we tailor the modelling to your specific question and can integrate the results into a broader climate risk and adaptation assessment.
