    Verification of the Chesapeake Bay Model: Chesapeake Bay Hydraulic Model Investigation

    Freier Zugriff

    The Chesapeake Bay model, a fixed-bed model constructed to a horizontal scale ratio of 1:1000 and a vertical scale ratio of 1:100, reproduced the Chesapeake Bay from the ocean to the head of tides for each tributary. Reproduction extended to the +20 ft contour. The model was equipped with the necessary appurtenances to accurately reproduce and measure tidal heights, tidal currents, salinity distributions, and freshwater inflows. Due to the innnense size of the model (8.6-acre model housed in a 14-acre building), complete computer control and data aquisition capabilities were provided. Severe limitations in prototype data in addition to substantial wind contamination of those data necessitated a detailed data analysis program which resulted in a modified approach to physical model verification. This was accomplished in the following two separate modes of operation: (a) verification for tidal heights and tidal velocities using an M?constituent tide and a constant long-term freshwater inflow and (b) verification for salinities using a typical 28-day tidal cycle (with long-period wind energy filtered out) and inflow hydrographs reproduced in 2-week time-steps. A bubbler system was incorporated in the model to statistically reproduce the vertical mixing caused by wind fields acting on the prototype. Excellent verification of the model was achieved._x000D_ _x000D_ NOTE: This file is large. Allow your browser several minutes to download the file.
