1D Urban Solver

Model the urban drainage system and how it interacts with surface flows

Flood Modeller allows you to combine surface and subsurface flow to obtain a detailed and integrated understanding of flood risk in urban areas, using the powerful user interface. Based on the U.S. Environmental Protection Agency's Storm Water Management Model (SWMM), it enables you to develop integrated catchment and system-based solutions within a single modelling solution.

Key facts

  • Easily build, run and visualise your drainage and pipe networks directly within the GIS user interface

  • Up to 49% faster than other benchmarked software

  • Use the fully integrated capabilities to model the river, urban drainage and surface water flood mechanisms across an entire catchment

  • Benefit from the advanced features of Flood Modeller, including the extensive range of hydrological approaches, advanced structures, productivity tools and more

  • Build on your existing drainage models by importing them directly into Flood Modeller

  • Run your models using the Flood Cloud service

Modelling river systems, surface water or urban drainage networks separately can provide important insights. However, using “separate” models to represent the different systems can often make it very difficult to represent the combined flood risk accurately. 


With Flood Modeller, you can use the 1D river solver to model river channels, or its 2D solver to model surface water flow, whilst linking to the 1D urban solver to model the interaction with and the impact on the drainage network.

Where pipe or drainage networks overflow in the 1D urban solver, links to Flood Modeller's 1D river or 2D solvers can be incorporated to model the resulting surface flows and possible flood scenarios for the area of interest. 

 

When fully integrated modelling is not required, the software excels at the modelling of sewer networks and other drainage systems. It is extremely powerful for modelling inflow and infiltration as well as combined sewer overflows, for evaluating the impact of extreme events on sewer systems.​

The GIS interface allows you to view time series results by plotting multiple variables, from multiple nodes and links, over a specified time range. Long section plots are also available and show the water level along the most direct “route” between any two specified nodes. These plots can be animated to show the water level adjust over time.

​When users have many models to run, they can utilise the Flood Modeller batch runner tool to setup a suite of simulations and leave the software to efficiently manage the running of all Flood Modeller models. ​

Users of the 1D urban solver benefit from the GIS user interface and visualisation tools within Flood Modeller to quickly undertake their integrated modelling studies. They also have the option of utilising the Flood Cloud service.

Benchmarking

Using a real-world case study, we have benchmarked Flood Modeller’s 1D urban and 2D ADI solvers (linked) against two other widely available software products.

✔️Up to 49% faster than other tools

✔️Results were not sensitive to the timestep selection

✔️Outputs reflected the flood mechanisms

✔️Numerically stable throughout the simulation
