Cutting Edge Overland Flooding Analysis

Efficiently analyse a site to show how water will run over the ground surface and determine the position of the blue/green corridors.

  • Instantly define problem areas with definable depth bands ranges and velocity or hazard rating arrows to the flooded area

  • Visualise results by displaying as solids or contours or as a 3D animation

  • Get a detailed analysis of flood levels within defined areas of the site.

  • Generate graphs to show the flooded depths and either the hazard rating or velocity.

  • Apply land use settings to the road surface, permeable areas or user defined zones.

  • Define water transition and recharge rate values, ensuring you model surface water flow accurately.

Drainage design: Feasibility design in Sketch with Causeway Flow

Quick, Simple Feasibility Design

Quickly produce feasibility designs with Causeway Sketch to assess the viability of a project.

  • Intuitive outline design at the pre-planning stage of a development
  • Outline designs can be converted to detailed designs within Flow seamlessly, without the need to double handle design data.

Advanced intuitive tools for efficient and optimal design

Empower engineers, consultants, developers and approving authorities to deliver an optimal and compliant design.

  • Intuitively model more accurate SUDS components such as flow-through pond and permeable paving with perforated pipe. 
  • Get results closer to the real-world by using the state-of-the-art hydraulic SWMM5 engine.
  • Better visualise designs with live 3D visualisation synchronised with the longsection, graphs and the hydrograph.

Real time, fully integrated design

Our drainage design tools integrate to complement the way you work. For complete live design use within the Causeway Live Design platform or utilise standalone using Causeway PDS or with AutoCAD and Civil 3D integration.

  • Make huge productivity improvements by streamlining the drainage design process.
  • If using on Causeway Live Design, drainage networks are designed hydraulically as you lay them out without any need to switch between design packages.
  • Add flow controls and storage devices as you design.
  • Save hours with real time amendments to designs in one environment ensuring iterations are reflected throughout the design.
  • Reduce the risk of out-of-date designs and clashes. Lock drainage networks to the road design for better control.
  • Get better visualisation of the whole site by switching on the 3D view at the same time as the plan, showing you live impact of changes in both views simultaneously.
