Aquanuity Unveils AquaTwin Sewer 2D for Overland Flow and Quality Modeling

Key Highlights

• Automated highly efficient and robust unstructured 2D triangular mesh generation.
• Overland flow, quality and infiltration (surface system) are modeled using the conservative formulation of the 2D Shallow Water Equations and advanced finite volume scheme.
• Fully integrated with the AquaTwin Sewer 1D sewer collection network modeling engine (sub-surface system) with no duplication of data.
• Powerful tool for simulating flood extent and flood inundation in urban areas.

Aquanuity, Inc., the leader in strategy-led simulation-powered water infrastructure digital twin software, today announced the first quarter 2024 release of AquaTwin Sewer 2D for ArcGIS Pro. The product extends the powerful sewer network modeling capabilities (sub-surface system) of AquaTwin Sewer by giving users the ability to accurately model overland runoff (surface system). It further substantiates Aquanuity’s steadfast commitment to delivering value-driven geocentric innovation to its customers.

Pluvial flooding in urban areas is characterized by a gradually varying inundation process caused by surcharge of the sewer manholes. AquaTwin Sewer 2D efficiently simulates the dynamic interaction between the sewer network (sub-surface system) and the overland flow (surface system) in order to accurately predict the flood inundation extents. The hydrodynamic simulation of the sub-surface system is solved using the 1D Saint-Venant equations and the hydrodynamic simulation of the surface system inundation is solved using the 2D shallow water equations. The resulting fully integrated 1D-2D model is a very useful and powerful tool in simulating flood extent and flood inundation in urban areas.

“AquaTwin Sewer 2D continues our strategy of raising the bar and setting new standards in ArcGIS Pro-centric water infrastructure digital twin innovation,” said Paul F. Boulos, Aquanuity Chairman and CEO. “It combines unprecedented 1D and 2D hydrodynamic simulation speed and reliability with highest performance geospatial functionality to help users to plan, design, operate and sustain better, safer, more resilient, and more efficient urban drainage infrastructure systems. We are thrilled to introduce this breakthrough digital solution to help utilities better meet the needs of their growing customer base and best serve and protect their communities and the ecological health of our waterways.”
