  • When can you trust a flood model? Accuracy, calibration, and uncertainty explained.

    Flood models are used to make important decisions: That’s why one of the most common questions in hydraulic modelling is: How accurate is the model? It’s a reasonable question. Engineers spend significant time calibrating models against observed water levels, flow rates, and flood extents. A model that cannot reproduce reality has limited value for planning,…

  • Why integrated hydraulic modeling is becoming essential for Middle East water infrastructure

    Across the GCC and wider MENA region, utilities, municipalities, and engineering consultancies are accelerating investment in hydraulic modeling, stormwater management, flood resilience, and wastewater infrastructure modernization. From Dubai and Riyadh to Doha and Jeddah, large-scale urban expansion and climate-driven rainfall events are increasing pressure on drainage networks, sewer systems, and water infrastructure. Integrated approaches can…

  • How our open-source GitHub repository grew from a simple idea into a global engineering community

    Engineers working in hydraulic modeling are increasingly turning to GitHub, scripting, and AI tools to automate workflows and extend their models – including our customers. GitHub has become the world’s largest platform for sharing open-source code. Engineers, researchers, and developers use it to publish everything from small scripts to full software projects. Many widely used…

  • Integrated catchment modeling explained: How rivers, sewers and surface water interact

    Integrated catchment modeling is the simulation of how water moves across an entire catchment by combining rivers, drainage networks, and surface flow within a single model. It allows engineers to understand how different parts of a water system interact during events such as flooding by performing complex hydraulic modeling. This approach combines 1D and 2D…

  • Hydraulic modeling explained: a guide to 1D, 2D and integrated catchment modeling

    Hydraulic modelling is the simulation of how water flows through systems such as pipes, rivers, and surface floodplains. Engineers use it to predict water levels, flow rates, and flood risk, helping design and manage water infrastructure under different conditions. Hydraulic modeling often combines 1D and 2D approaches to represent both network flows and surface behavior…

  • Aguas de Alicante’s digital twin water transformation

    Aguas de Alicante is one of Spain’s oldest water utilities, with roots dating back to 1898 when potable water was first brought to the city of Alicante. It operates under a public-private model and manages the integrated water cycle — including water capture, treatment, distribution, sewerage, and wastewater purification — for Alicante and surrounding municipalities.…

  • Jacobs: How 1D + 2D modeling in InfoWorks ICM is controlling stormwater in Toronto (and saving $$$)

    The Woodborough Park neighborhood in Toronto is part of the Fairbank-Silverthorn area, which experiences significant flooding challenges, especially during heavy rainfall events. Their two big problems are a long history of basement flooding and sewer system overloads. Like many North American cities without separate sewer and water systems, they struggle with CSOs (Combined Sewer Overflows),…

  • Houston’s Stormwater Master Plan: a modern approach to citywide modeling

    Houston’s relationship with water has always been complex. Sometimes called the “Bayou City”, Houston has been flooding since it was founded in 1836. Flat terrain, lots of concrete, expansive development, its position near the coast, and increasingly intense rainfall events have made stormwater management one of the city’s most critical infrastructure challenges. But they’ve been…

  • InfoWorks ICM 2026.3: Raster workflows, expanded subgrid meshing, 2D boundaries, and a more polished interface

    As urban drainage and flood modeling challenges continue to grow in complexity, modelers need tools that can scale with larger datasets, richer terrain detail, and increasingly global data sources, without adding friction to everyday workflows. In InfoWorks ICM 2026.3, we’ve focused on strengthening some of the most heavily used parts of the platform: raster-based workflows,…

  • Implementing the updated Australian Rainfall and Runoff guidelines to account for climate change

    With heavy short-term rainfall events becoming more intense, it’s critical that Australia’s flood maps are dynamically altered to include the most up-to-date ARR guidelines. Because our software offers customizable rainfall calculations, you can adjust equations to go beyond standard calculations – to account for climate change or to apply specific details that affect your location. Australia is…
