Before about 20 years, there was no design consideration for climate change, specifically for rising sea levels due to global warming. Based on sea level measurements, there was clear evidence that the mean sea level increases based on which several RFPs requested to consider the sea level rise in the design of coastal structures and flooding. Since there are many uncertainties in the projected models where several emission scenarios produce different sea level rise. Designers choose the worst-case emission scenario when determining the design water level. This would, in turn, result in a relatively pricy solution.

Subject: Are we properly considering sea level rise effects in our work?
A recent ASCE Civil Engineering Source article by Scott Douglass asked, "What future sea-level rise should we design for today?" It's an important question for designers, planners, and those who write and review environmental assessments in most areas.
Sea level issues arise in obvious ways such as tidal flooding, increased wave penetration, and submergence of structures, but also in less obvious ways such as decreased land drainage slope, increased salinity intrusion, and contamination of groundwater supplies.
Are we properly considering sea level rise effects in our work? What should we be doing differently?
