Morphostatic Long-Term Hypsometric Analysis Of Coastal Bay Environments: Hog Island Bay, Virginia, Kathleen Marie Overman Apr 2001

Morphostatic Long-Term Hypsometric Analysis Of Coastal Bay Environments: Hog Island Bay, Virginia, Kathleen Marie Overman

OES Theses and Dissertations

Sea level has been rising at a variable rate since the end of the last glaciation approximately 18,000 years ago. As the transgressing sea inundates the shore areas a series of landform state changes occur in coastal regions. One such change of state in a coastal paleo-river channel is from an estuary into a coastal lagoon. At large temporal intervals (thousands of years) the hypsometry of a coastal lagoon varies as a result of sea level rise due to these changes of state. Using a morphostatic technique, the time period in which an estuary transforms into a coastal lagoon can …


Comparison Of Statistical And Model-Based Hindcasts Of Subtidal Water Levels In Chesapeake Bay, Kathryn Thompson Bosley, Kurt W. Hess Jan 2001

Comparison Of Statistical And Model-Based Hindcasts Of Subtidal Water Levels In Chesapeake Bay, Kathryn Thompson Bosley, Kurt W. Hess

CCPO Publications

Subtidal water levels in Chesapeake Bay, which can have amplitudes as large as 1 m at Baltimore, are an important component of total water levels. The most importance forcing mechanisms for these variations are surface winds over the Bay and coastal subtidal water levels. Two methods for hindcasting subtidal water levels in the Bay were developed: statistical prediction (based on multiple linear regression) and a barotropic numerical circulation model-based prediction. The hindcast water levels were compared with the observed values at three key locations (Chesapeake Bay Bridge Tunnel (CBBT) in the lower bay near the mouth, Solomons Island at midbay, …


Can Long-Term Variability In The Gulf Stream Transport Be Inferred From Sea Level?, Tal Ezer Jan 2001

Can Long-Term Variability In The Gulf Stream Transport Be Inferred From Sea Level?, Tal Ezer

CCPO Publications

Recent studies by Sturges and collaborators suggest a simple, but powerful, technique to estimate climatic changes in the transport of the Gulf Stream from the difference between the oceanic sea level calculated with a simple wind-driven Rossby wave model and the observed coastal sea level. The hypothesis behind this technique is tested, using 40 years of data (1950 to 1989) obtained from a three-dimensional Atlantic Ocean model forced by observed surface data. The analysis shows that variations in sea level difference between the ocean and the coast are indeed coherent with variations of the Gulf Stream transport for periods shorter …
