Over the past five years, concern regarding probable changes in eustatic 

 sea- level in response to global warming- greenhouse effect has given rise to a 

 flurry of attempts to integrate varied geophysical data into a solid 

 predicative framework. Recent predictions of global sea- level rise by year 

 2100 have ranged between 0.5 - 3.5, with 1.5m being a good working estimate 

 for scientists and coastal managers, even though this is bound to be revised 

 in light of new data. A rise in sea- level of this magnitude would greatly 

 impact the current coastal zone through erosion and breaching of barrier 

 islands, salt intrusion, wetland destruction and vegetative displacement, 

 topsoil erosion and sediment translocation offshore, changes in weather 

 patterns and hydrologic cycle, and increased inland range of tides and marine 

 storms. Although the social, legal, and environmental implications of such 

 events have yet to be grasped fully, attempts have been made to construct 

 conceptual models that consider these large scale effects as well as 

 "regional" concerns ranging from the necessity of exhuming the dead in 

 threatened coastal areas to the human health implications of increasing 

 temperature and water cover in temperate regions. Much of this work is of 

 great value, however, the effects of sea- level rise on containment of 

 hazardous wastes in coastal dumpsites, landfills, and subsurface containers 

 has received very little attention in the technical literature. A review of 

 the models and recommendations of this literature indicates that the magnitude 

 and scope of hazardous wastes in the coastal zone have not been appreciated or 

 thought through. The U.S. generates approximately 170 million tons (MT) of 

 solid and 275 - 1000 MT of hazardous waste annually. Of the nearly 800 final 

 sites on the U.S. Environmental Protection Agency (USEPA) National Priority 

 List (NPL) for Superfund cleanup, which were selected from a proposed list of 

 29,000, approximately 75% are in coastal states. A random sampling of coastal 

 plain states indicates that 25 - 60% of the NPL sites occur in or near 

 estuarine, riparian, or coastal lowland ecosystems. These estimates do not 

 include private or unauthorized. (Authors) .

Tidal fluctuations of inshore ponds separated from the ocean by a sand 

 bar are investigated. The pond fluctuations are reduced in amplitude and 

 delayed in time relative to the ocean oscillations. The aquifer configuration 

 and the shape of the pond produces asymmetric oscillations in the pond whereby 

 the average pond level differs somewhat from the average sea-level. 



Mathematical models are used to describe the flow of water in an uncon- 

 fined aquifer between the ocean and the tidal pond. These models assume
