Coldwater Consulting has extensive experience in the development and application of numerical models for the simulation of hydrodynamics and sediment transport processes in complex environments. Our expertise includes wakes, circulation and sediment transport processes under combined waves and currents, and two-dimensional wave transformation modelling.


We have developed several in-house models that have been successfully applied to solve problems within river, coastal, and estuarine environments.
| PTM is a particle-based sediment transport model. Developed for the US Army Corps of Engineers, this model is capable of accurately simulating the fate of sediments disturbed by waves, currents and/or dredging activities. |
| The ship-generated hydrodynamics model (SGH) allows simulation of the effects of commercial shipping in waterways including the generation of drawdown and wakes and their impacts on the shore. |
| For high-speed vessels, LSV is a Lagrangian model that can simulate the wakes generated by both sub- and super-critical boats and predict the transformation of those wakes as they propagate to the shoreline. |
| The phase-resolving refraction-diffraction model, Hyper, can be used for areas where wave reflections are important such as harbours and marinas. This model can also handle floating structures, wave fences and partially-reflecting surfaces. |
| The CoastL model is a nearshore wave and wave-induced current model that includes full wave-current interaction, combined refraction-diffraction, a two-equation turbulent kinetic energy viscosity closure, and an advanced wave-current bottom friction closure. |
