Modelling

Overview

ABP Marine Environmental Research Ltd (ABPmer), has a long established Modelling team which provides a comprehensive service to support hydraulic investigations of river, estuary and coastal systems, offering descriptions of:

  • Flows
  • Waves
  • Sediment transport
  • Water quality

To ensure appropriate representation of such processes, the properties and complexities of each system need to be examined and understood. Therefore, good site information is a fundamental requirement for model selection, design, construction and proving. Our in-house Data team provides this through field survey, data collation, processing, analysis, mapping and presentation capabilities.


The Modelling team aims to offer the best available solution to meet the individual project requirements. We maintain a range of sophisticated numerical modelling software and recognise the importance of understanding the limitations inherent in all modelling approaches. A correct problem definition and appreciation of the properties driving each system identifies which model or combination of models is suitable to the task.

Numerical Modelling

The primary suite of models which are supported by the team include:

  • MIKE 11 - 1D modelling tool from Danish Hydraulics Institute (DHI) to examine hydraulic flows in open channel systems. Modules: Hydrodynamics, Structures, Advection - Dispersion, Cohesive Sediment, Sediment Transport and Water Quality.
  • MIKE 21 - 2D modelling tool from DHI to examine complex free surface flow regimes in estuaries and coasts. Modules: Hydrodynamics, Nested Hydrodynamics, Advection- Dispersion, Nearshore Spectral Wind-Waves, Mud Transport, Sand Transport, Boussinesq Waves, Particle Transport and Tidal Analyses.
  • MIKE 3 - 3D modelling tool from DHI for complex free surface flow regimes based on a rectilinear grid arrangement with a fixed grid spacing through the water column. The ability to allow for a non-hydrostatic pressure distribution allows the model to resolve vertical flow structures resulting from steep gradients in bathymerty associated with submerged channels or mounds. Modules: Hydrodynamics, Advection-Dispersion, Mud Transport.
  • MIKE FM - 2-D & 3-D flexible mesh modelling tool from DHI used to examine complex free surface flow regimes where the limitations of rectilinear or curvilinear grids require an unstructured grid approach. Modules: Hydrodynamics, Advection-dispersion, Spectral Waves, Mud Transport and Sand Transport.
  • LITPACK -1D modelling tool from DHI to examine nearshore littoral processes and coastal evolution.
  • DELFT 3D - 2D & 3D modelling tool from Delft Hydraulics to examine complex free surface flow regimes in estuaries and coasts. Modules: Regular and Curvilinear Grids, Waves, Hydrodynamics, Sediment Transport, Structures and Oil Spill.
