The tidal forecasting model is a harmonic analysis tidal forecasting system based on the Foreman (1992) with model-predicted tidal parameters. Five tidal constituents M2, N2, S2, K1, and O1 are included in this system.

Two choices are available in this system:

  • 1. Forecasting the snapshot of the distribution of water level and tidal currents over the entire Ogeechee River Estuary for a selected time.


    To view the tidal chart at a selected time, 2 steps must be followed:

    • Step 1: Select year, month, day, hours and minutes with a format as YYYY/MM/DD/hh/mm. For example, the user wants to view the tidal chart at 13: 20 PM on November 2,1999, he or she should type “1999/11/02/13/20.” The model will use the eastern time of USA (now still use GMT)

    • Step 2: Send the job by click “submit" button. It should take about a few minutes for the model to calculate the amplitude and phase of tidal elevation and currents. Sometimes, it might be very slow due to internet connection.

  • 2. Forecasting tidal elevation and current at a selected site for a selected period.

  • To view the time series of tidal elevation and current at a selected location for a selected period, 4 steps must be followed:

    • Step 1: Select a site on the map by click the mouse at that point. After that, longitude and latitude at that selected site will automatically appear on the screen. The user also could modify the location by modifying the values of longitude and latitude.

    • Step 2: Select year, month, day, hours and minutes for starting time with a format as YYYY/MM/DD/hh/mm. For example, the user wants to view the tidal chart at 13: 20 PM on November 2, 1999, he or she should type “1999/11/02/13/20.” The model will use the eastern time of USA (now still use GMT).

    • Step 3: Select a depth within the water column and the period (days) for time series. The depth at a selected site must be in the range of the total water depth at that point. The total water depth will appear on screen for user’s reference.

    • Step 4: Send the job by click "submit" button
