Figure 4 &wa the result produced by the model for day l21 (the end of April) in 1976. It indicates tbat there are appreciably fewer algae in the EIollmds Diep at the Volkerak sluice6 than in the river channels upstream, and thac very high levels of chlorophyl wcur near che Earingvliet slgices . The picture is different: fer 1982 (see Fig. 5). In the Bollasds Rdep the chlotuphpl levels are lower than is the river ehwnela, but towards the Hafiupliet sluices they decresse even furLher. mia is fully in agreement With the picture of measured chloropliyl levels in that year.
