3-18. Detachment planners can better determine the optimum conditions if they can visualize the tide (and tidal current) during their proposed infiltration window. They can determine tide height at any point during the tidal cycle using the matrix (Table 3-1) or graphical methods (Figure 3-5). How-to instructions for each method are explained in the charts. Tide and current predictions are affected by meteorological conditions, and therefore may not be 100-percent accurate. Local knowledge is also important.
