Our Technologies

Using state of the art flood prediction technology and the latest data, we can provide the highest possible accuracy for our clients

Ambiental have a core specialism in flood mapping and modelling. We undertake modelling at all scales and for all use-cases all around the world – but with a particular focus in the UK.

Not only are Ambiental Environmental Assessment experienced with working with a wide range of commercial mapping and modelling tools, we have also developed our own proprietary suite of flood modelling tools – the Flowroute suite. These models are owned by Ambiental and have been used in the industry for over 10 years.

Ambiental’s Flowroute-i in a nutshell


  • It's a highly versatile tool with a range of features used in any combination to asses flood risk
  • Precision 2D+ hydraulic multisource modelling
  • Models pluvial (surface), fluvial (river), and tidal water sources
  • Accurately handles high-density urban environments
  • Accounts for drainage and flood defences
  • Accounts for ground roughness and infiltration
  • Can predict to individual property level

About Flowroute-i

Flowroute-i has also been validated by the EA as part of the “Benchmarking the latest generation of 2D hydraulic modelling packages” (Report – SC120002). The entire suite is highly compatible with common GIS platforms and scripting approaches (e.g. python/GDAL) which provides a clear and concise way of setting up batches of simulations.

Flowroute-I is aimed towards providing an in-house modelling tool with a wide range of applications. The advantage in using this software is that simulations can be specifically defined by the user according to their needs, allowing runs to be conducted for as many scenarios and iterations as required without the need for laborious repetitive tasks. This provides considerable cost-savings for large modelling projects.

What can Flowroute-i do?

Flowroute-i 100 year flood map

Flowroute-i was designed specifically to simulate river and floodplain dynamics in complex urban and rural areas, as well as in mountainous regions. It models the complex interaction of pluvial (surface), fluvial (river), and tidal water sources. It also considers drainage, infiltration, and groundwater levels.

Using Flowroute-i we can also model what might happen if flood defences are breached, pipes burst or sewers overflow, and what could happen if water is pumped out of the area or escapes at a watershed point. This makes our modelling exceptionally flexible and realistic, giving our clients a far more precise and detailed understanding of the risks.

Flowroute-i treats a floodplain as a grid of cells, with flow occurring between edge-connected cells at each time step. This offers an excellent dynamic picture of a flooding event, as well as highly accurate maximum depth and velocity at all points within the study area.

We continually optimise Flowroute-i to reduce processing times and make the most of modern computing power. Today it can be run in a distributed or cloud computing environment and can simulate flood flows across hundreds of millions of cell domains in parallel.

Other technical solutions we can provide

As well as our own independent modelling software, we also use a range of industry-leading applications, including TuFlow, Flood Modeller, and MicroDrainage (XP Solutions). With these key solutions, our experts can support our clients’ needs from flood risk through to engineered solutions for surface water drainage.
