OCEN 683
Estuary Hydrodynamics
Fall Semester 2003
Instructor: Dr. Billy L. Edge
Office: 236A WERC, Phone: 845-4515
Homework 1
1. Develop a graph that shows the theoretical tide one would expect to observe traveling around
the earth at latitudes 0, 30, 60 and 90 degrees. Assume that the moon is at its maximum
declination. Show what the ideal water surface would be.
2. Using the software XTIDE, develop a lunar month and a 6 month plot from July 1, 2000 for
the following sites, Panama Canal (Atlantic Ocean), Charleston, South Carolina, and Boston,
Massachusetts.
3. Consider that the theoretical tides are created by both the moon and sun and that there is no
declination of the earth moon-sun system. Develop a graph of the tides at 30 degrees north for
(a) moon and sun in alignment, and (b) moon and sun 90 degrees out of phase.
4. What is the minimum period of installation of a tide gage that you would recommend and why.
5. Select an estuary in the United States that you think it would be interesting to model. Do this
in conjunction with some available bathymetric data. Examples could be San Francisco Bay,
Galveston Bay, Charleston Harbor, Grays Harbor, Noyo Bay, James River, Indian River,
Delaware Bay, Corpus Christi Bay, St. Johns River, Mason Inlet, Cape Fear River, etc.
