Blue Coast staff have over 35 years of combined experience conducting numerical modeling studies of waves, tidal and riverine hydrodynamics, coastal and upland flooding, and sediment transport. We have a fundamental understanding of how the models we use were developed and their capabilities and uncertainties. Blue Coast uses our expertise to judiciously develop successful, cost effective modeling strategies to inform project design and support project permitting. Our modeling work capabilities include one-, two- and three- dimensional hydrodynamic and water quality modeling, wave transformation modeling, and sediment transport and shoreline change modeling.

Blue Coast staff led the modeling team on the project to develop and implement a three-dimensional unsteady tidal hydrodynamic and salinity model for the Big Quilcene River and Estuary to inform design and selection of proposed restoration alternatives to reconnect portions of the floodplain at the estuary mouth. The primary purpose of the modeling was to address concerns about impacts to extensive shellfish beds within the estuary. Work included review of oceanographic data collected for the model calibration, model grid development, model calibration (water levels, salinity, and currents), development of model boundary conditions, completion of model simulations, and synthesis and reporting of model results. Blue Coast staff assisted HCSEG with presenting results of the modeling work to project stakeholders. Blue Coast is currently in the scoping phase (as a subconsultant) to complete additional hydrodynamic modeling and provide design support for 30% design.

Blue Coast has developed a 1-dimensional (1-d) HEC-RAS model of Martha Creek to estimate velocities and, water surface elevations and water depths in the existing creek channel, then used the model to design a new open channel which is optimized for low
Blue Coast are the design engineers for this stream and habitat restoration project. Blue Coast has developed a 1-dimensional (1-d) HEC-RAS model of Martha Creek to estimate velocities and, water surface elevations and water depths in the existing creek channel, then used the model to design a new open channel which is optimized for low and high flows. Blue Coast also calculated wind-waves and longshore drift at the outlet of Martha Creek to determine the design elements required for the creek to maintain the tidal channel into Port Susan Bay. Blue Coast used ArcGIS to develop a 2-dimensional (2-d) design conditions model which incorporates the 1-d hydraulic model output and 2-d water level mapping to illustrate tidal inundation of the project design and that there is no additional flood risk to upstream or adjacent properties being created by the project. In addition, the 2-d design conditions model is being used to incorporate habitat features such as large wood, tidal pools, and vegetation. The project was constructed in August 2020.
