Integrated catchment modelling is the most high-resolution, inclusive modelling technique. It takes into account subsurface and overland flow routes and pathways and integrates the hydraulics and hydrology of natural and man-made environments into a single model.
Our team has supported many projects with varying complexities and development scales.
We’re experts in ESTRY/TUFLOW and Infoworks ICM to deliver high-quality studies.
Benefits Of Integrated Catchment Modelling
Using the latest software, such as Infoworks ICM, Aegaea can support the delivery of complex modelling for surface water management plans and drainage area plans.
‘Integrated Catchment Modelling’ means incorporating all sources and receptors, typically in an urban environment, to develop a complete picture of the causes of flooding.
Flow pathways and interactions between the surface (roads, greenspace, urban features) and the subsurface (sewer networks, surface water sewers) are complex and need to be modelled discretely and carefully.
The interaction between the two can substantially affect the outcomes and impacts of the modelling study, so it is important to represent them all at the same time. Surface flooding could be caused by overland flow, blocked drains, or recharge from the sewer network.
Detailed modelling of surface water systems and combined systems underground, as well as detailed representation of the surface, highlights flooding problems holistically and helps to identify solutions to flood issues. An integrated model can show under-capacity pipe networks, pinch points in drainage systems, and the impact of interventions.
As such, an integrated catchment model is the only way to ensure that you understand all the risks and opportunities in an urban area. They are relied upon across the UK and internationally to deliver integrated urban solutions to flooding.
Urban Flooding
Increasingly, leading local flood authorities are requesting integrated modelling to assess urban sites.
They appreciate that the subsurface sewer systems impact storage potential and flow conveyance, and they request that these models be used to assess the pre- and post-development situations.
Aegaea can develop these models using appropriate software, offering you confidence in the delivery of urban regeneration.
High Specification Software
Infoworks ICM enables above-ground and below-ground simulation simultaneously, meaning the transition of water in the urban area is simultaneous, accurate, and appropriate.
This unified approach is the gold standard of urban flood modelling, delivering high-quality results for any development or area strategy.
That’s why ICM is trusted to deliver surface water management plans, drainage area plans, and integrated assessments across the urban space.
ICM software is the leading industry modelling package for developing integrated sewer and watercourse models. By integrating existing sewer assets with watercourses, ICM provides the most comprehensive method for modelling urban and river catchments within a single model in both 1D and 2D.
ICM software provides a solution for sewer and river issues or a combination of both in one package across various design rainfall durations and return periods.
How Our Team Can Support You
Our experience developing integrated catchment models covers urban developments, surface water sewers, overland flow, and fluvial and tidal boundaries.
Using the latest software (Infoworks ICM and TUFLOW) can offer high-resolution, high-impact results across broad strategic levels and site-specific assessments.
