FAQS

OpenFlows FLOOD is flood modeling software for analyzing and mitigating flood risk in urban, riverine, and coastal areas. Using spatially distributed numerical models, users can quickly simulate all hydrological and hydraulic processes to support emergency planning and green-initiative design. Apply a multi-scale 1D/2D approach to support flood early warning systems (FEWS). 

Flood simulation software helps model and predict the behavior of floods. It uses data about terrain, rainfall, and infrastructure to create a virtual representation of a flood event. This enables engineers, planners, and emergency managers to understand where flooding will occur, how deep it will be, and how quickly it will spread. By simulating different scenarios, flood simulation software helps to assess flood risk, design effective mitigation strategies, and improve overall preparedness for flood events. 

OpenFlows FLOOD is a critical tool for enhancing flood preparedness in several key ways: 

Comprehensive risk assessment: It allows you to simulate any type of flood—from intense rainfall in urban areas to coastal storm surges and river flooding. This enables the creation of detailed flood hazard, vulnerability, and risk maps that identify the people and infrastructure most at risk. 

Improved infrastructure design: By modeling how different mitigation measures will perform, you can design more resilient infrastructure. This includes everything from optimizing the design of flood defenses like levees and seawalls to improving the capacity of stormwater drainage networks. 

Effective emergency planning: The software's outputs are essential for developing robust emergency action plans. This includes defining evacuation routes, positioning emergency resources, and establishing effective communication strategies for at-risk communities. 

Flood early warning systems (FEWS): OpenFlows FLOOD provides the core modeling engine for flood forecasting and early warning systems. By integrating with real-time data, it can predict flooding hours or even days in advance, giving authorities crucial time to warn the public and prepare a response. 

OpenFlows FLOOD is a single, integrated 2D flood modeling tool, while HEC-RAS requires HEC-HMS for hydrology. Based on an open-source engine, OpenFlows FLOOD's source code is accessible, unlike the closed-source HEC-RAS. OpenFlows FLOOD uses the digital surface model to automatically calculate runoff, removing the need for manual catchment data. It also features a full GIS-enabled interface for visualization, whereas HEC-RAS relies on third-party tools like ArcGIS for advanced mapping. 

As part of Bentley's ecosystem, OpenFlows FLOOD offers powerful interoperability. Generate models from iTwin Capture reality meshes, create stunning 4D visualizations in Bentley LumenRT, and integrate with OpenCities Planner's digital twins. Seamlessly couple 1D networks from OpenFlows Sewer for a complete modeling cycle. This integration, combined with full GIS capabilities, ensures an efficient workflow and compatibility across a broad portfolio of products, from design to analysis and visualization. 

OpenFlows FLOOD differs from OpenFlows Storm or OpenFlows Sewer by using a 2D surface model for more realistic runoff analysis. It automatically calculates factors like time of concentration and surface depressions from terrain data, removing the need for manual input required by other tools. While products like OpenFlows Sewer use simplified, conservative methods like SCS CN, OpenFlows FLOOD generates more realistic hydrographs and can perform advanced water quality and pollutant dispersion modeling.
