South Coast Engineers provided the coastal engineering expertise to this research project by the National Cooperative Highway Research Program of the National Academies of Sciences, Engineering and Medicine. The objective of the research was to develop a design guide of national scope to provide hydraulic engineers with the tools needed to amend practice to account for climate change. The approach originally developed in this research project for incorporating future sea level rise into coastal infrastructure design has subsequently been adopted by FHWA and is under consideration for adoption by coastal state Departments of Transportation.
