The Delaware Geological Survey will review recent scientific literature and assessments of sea-level change in Delaware and identify appropriate scenarios to use for planning purposes throughout the state. This project will also develop new inundation maps along Delaware's coast that correspond to the identified scenarios.
Open-File Report 50 presents and describes a database of geochronological information for coastal deposits of the US Atlantic and Pacific coasts, as well as for sites from the Pacific coast of South America. This database represents a synthesis of nearly forty years of study conducted by John F. Wehmiller and students in the Department of Geological Sciences, University of Delaware, as well as many collaborating colleagues.
DGS is building a database and web distribution system to collect, manage, and display high water marks (HWMs) that are observed throughout Delaware as a result of flooding events. Historical peak water levels can be extracted for past storms or for a selected geographic area. Development is being done in partnership with the Office of the Delaware State Climatologist, the Delaware Environmental Observing System (DEOS) and the Delaware Environmental Monitoring and Analysis Center (DEMAC).
