Abstract
In this study, a two-layer box model was constructed for the estimation of nutrient budgets in Inohana Lake Estuary, and the reliability of the model was evaluated by comparing the model-based ΔDIP and the average chlorophyll-a concentration measured in the surface. The surface chlorophyll-a was very significantly related to ΔDIP (R2 = 0.95). This result suggests that the model based on the mass balances of water, salt and nutrients can provide a good estimate of the seasonal nutrient behavior in Inohana Lake Estuary.
