Model and simulate extreme events using accurate and reliable flood risk analysis data

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).

Mitigate urban flooding

Urban flooding poses risks to residents, damages property and infrastructure, and disrupts urban services. Create efficient solutions that increase the resilience of urban drainage systems and implement mitigation measures, such as low-impact development and green initiatives. Mitigate these issues by producing detailed simulations to identify bottlenecks and hotspots that hinder the capacity of stormwater drainage systems.

Prevent riverine flooding

Calculate river flow to understand, evaluate, and optimize reservoir operations to minimize and prevent damages from riverine floods. Design and improve emergency structures and outline flood-resilient land use strategies, all within a climate change context. Simulate the exchange of water between the river flow and (sub)surface flow based on hydraulic gradients. Produce inundation maps, flood risk maps, and hazard maps that address riverine flows, river defense capacity, and large-scale land use changes. Estimate the drainage network from topographic maps and to interpolate cross sections in space.

Model coastal flooding

Coastal flooding can be caused by high tides, storm surges, and tsunamis, sometimes in combination with insufficient urban drainage capacity or high upstream river flows. Dynamically model complex array of processes related to coastal flooding to find accurate solutions for defining and improving storm surge and tsunami protection plans. 

Analyze flood inundation areas

Calculate the extent of flooded areas and estimate the flood hazard based on water column heights and peak flow velocities. Easily integrate models generated with OpenFlows SewerGEMS to simulate surface and stormwater flow. Create scenarios and make comparisons among different alternatives to rapidly find the best solution for flood risk mitigation.

Add real-world context, animation, and visualization

Explore and present model results using a wide range of integrated visualization capabilities, including the option to make smooth, continuous animations of the obtained results. Help stakeholders better understand the risks and impacts of flooding events and potential mitigation actions with integrated 3D reality models. Bring simulations to life by generating realistic visualizations of flood events using LumenRT.

Build and manage hydraulic models

Leverage and import many well-known external data formats to maximize ROI on geospatial and engineering data. Jumpstart the model building process and manage models effectively to keep focus on making the best engineering decisions.
