Estimating Exchange Rates of Water in Embayments using Simple Budget Equations.
Keith Sverdrup, University of Wisconsin-Milwaukee
Simple budgets may be used to estimate the exchange of water in embayments that capitalize on the concept of steady state and conservation principals. This is especially true for bays that experience a significant exchange of freshwater. This exchange of freshwater may reduce the average salt concentration in the bay compared to seawater if it involves addition of freshwater from rivers, R, and/or precipitation, P. Alternatively, it may increase the average salt concentration in the bay compared to seawater if there is relatively little river input and high evaporation, E. Since freshwater input changes the salt concentration in the bay, and salt is a conservative material, it is possible to combine two steady state budgets for a bay, one for salt and one for water, to solve for the magnitude of the water flows that enter and exit the bay mouth. Students will make actual calculations for the inflow and outflow of water to Puget Sound, Washington and the Mediterranean Sea and compare them to actual measured values.

Barb Tewksbury, Hamilton College
Barbara and David Tewksbury, Hamilton College Summary In this eight-part exercise, students download NOAA high resolution bathy/topo DEMs and TIGER census data to predict the location of shorelines, the extent of ...
Coastal Erosion Online Discussion
Sheila Roberts, Bowling Green State University-Main Campus
This assignment is designed to get students to see the application of geology to a local problem, coastal erosion along the Lake Erie shoreline. I think the strength of this assignment is that many of the students ...
