Tides

9. Tides#

Using the method described by Flather and Davies [1976], CROCO is able to propagate the different tidal constituents from its lateral boundaries.

To do so, you will need to add the tidal components to the forcing file.

  1. Edit crocotools_param.m section 5

    %%%%%%%%%%%%%%%%%%%%%

    % TPXO file name (TPXO7)

    tidename=[CROCOTOOLS_dir,'TPXO7/TPXO7.nc'];
    %
    % Number of tides component to process
    %
    Ntides=10;
    %
    % Chose order from the rank in the TPXO file :
    % "M2 S2 N2 K2 K1 O1 P1 Q1 Mf Mm"
    % " 1 2 3 4 5 6 7 8 9 10"
    %
    tidalrank=[1 2 3 4 5 6 7 8 9 10];
    %
    % Compare with tidegauge observations
    %
    lon0=18.37;
    lat0=-33.91; % Cape Town location
    Z0=1; % Mean depth of the tidegauge in Cape Town
