Reverification of the Chesapeake Bay Model.

Abstract

The Chesapeake Bay hydraulic model, an 8.6-acre fixed-bed model, constructed to a horizontal scale ratio of 1:1000 and a vertical ratio of 1:100, reproduces the entire Chesapeake Bay estuarine system from the offshore Atlantic Ocean to the head of tide for all tributaries. The model is equipped with the necessary appurtenances to accurately reproduce and measure tidal heights, tidal currents, salinity distributions, and freshwater inflows. It is the largest and one of the most sophisticated estuarine models of its kind. Complete computer control and data acquisition capabilities ensure accurate and precise monitoring and control throughout the 14-acre shelter. During the summer of 1980, unusual concrete expansion on the model resulted in compression and unequal vertical concrete movement. Damaged areas were remolded and all existing and new expansion joints were widened and filled with a closed cell expansion material. Reverification of the model was required following this rehabilitation effort. This report provides all the necessary information to adequately assess model reverification and model operating capabilities. Keywords: Lunar monthly tide; Fortnightly salinity response.
