Figure 4. Two examples of the output from a simple, organic waste dispersion model. In both examples the shaded area represents the net-cages. Example A: water depth 21 m; maximum current speed 31.3 cm s^-1; constancy factor (an estimate of the persistence of the direction of flow) 97.3%; the long axis of the cage group represents 54 m. Example B: water depth 20 m; maximum current speed 15.6 cm s^-1; constancy factor 35.4%; the long axis of the cage group is 30 m. (From Gowen et al., 1988)
