Abstract
Tides in the Delaware Bay (USA) have been modeled from 7000 years before present (7 ka) to the present day and for selected future sea-level rise scenarios (100 years, 300 years). Historic bathymetries were constructed through use of glacial isostatic adjustment models and a very high spatial resolution (< 100 m)="" was="" used="" at="" the="" shoreline.="" future="" bathymetries="" were="" obtained="" by="" extrapolating="" these="" glacial="" isostatic="" adjustment="" models="" and="" applying="" an="" additional="" eustatic="" sea-level="" rise.="" it="" was="" found="" that="" tides="" in="" the="" lower="" bay="" have="" remained="" fairly="" constant="" through="" time="" but="" that="" tides="" in="" the="" upper="" bay="" have="" increased="" steadily="" from="" about="" 4 ka="" to="" the="" present="" day;="" a="" nearly="" 100%="" increase="" in="" total.="" the="" future="" runs="" demonstrated="" spatially="" complex="" behavior="" with="" tidal-range="" changes="" of="" up="" to="">
