Flow Patterns & Velocity

Coastal waters and estuaries, as well as rivers and dams, are environments with significant impact on the regional economic and recreation activities as well as bio-diversity.

Challenges with Flow Patterns & Velocity

Coastal waters and estuaries, as well as rivers and dams, are environments with significant impact on the regional economic and recreation activities as well as bio-diversity. These systems can have a great range of shore-ocean and river-ocean interactions. Quantitative estimates of water levels, surface velocities and deeper circulation and mixing are needed to assess restorative projects or new infrastructure developments.

EEMS Capabilities

EEMS provides proven tools for simulation of hydrodynamics, including detailed analysis of flow patterns and velocity. These are also full linked to sediment transport and water quality to provide a comprehensive analysis. EFDC+ has been used in hundreds of riverine and coastal circulation models and in conjunction with EE provides you with powerful tools to assess environmental issues and solutions. Features of EFDC+ which assist coastal studies include:

  • Internally coupled wind wave module.
  • External coupling with any third party wave model.
  • Enhanced external coupling with the freely available third-generation wave model,
  • Pre-defined harmonic constants that are available for building site specific tide series.
