Abstract : This Coastal and Hydraulics Engineering Technical Note (CHETN) describes the mathematical formulation and numerical implementation of a culvert in the Coastal Modeling System (CMS) operated through the Surface-water Modeling System (SMS). A coastal application is provided to illustrate the implementation procedure at Poplar Island, MD. Culverts are a common coastal engineering structure typically used in coastal wetlands to control waste and storm water discharges, act as salinity barriers, optimally distribute freshwater, and manage sediment transport (Figure 1). In coastal applications, the culverts often connect open water bodies of similar water surface elevation to enhance flushing or conduct flow through levees or causeways. Since culverts are a significant component of hydrodynamic and sediment transport controls in the coastal zone, it is important that the CMS simulates their effects. The implementation of culverts in the CMS is based on equations developed by Bodhaine (1982). As a validation, the culverts are applied for the hydrodynamic calculations in a wetland application in Chesapeake Bay, Maryland. The CMS, developed by the Coastal Inlets Research Program (CIRP), is an integrated suite of numerical models for simulating water surface elevation, current, waves, sediment transport, and morphology change in coastal and inlet applications. It consists of a hydrodynamic and sediment transport model, CMS-Flow, and a spectral wave model, CMS-Wave (Buttolph et al. 2006; Sanchez et al. 2011a; Sanchez et al. 2011b; Lin et al. 2008). Both are described in Part I of this series (Li et al. 2013).
