Description
Summary:The artificial eutrophication of lakes and reservoirs is recognized worldwide as a serious problem of water quality management. Lake Kasumigaura, the largest shallow lake in Japan, showed the typical signs of eutrophication over the last decades. This is due to the increased nutrient loadings of urbanization, agricultural development and fishing culture. A lot of countermeasures are now being planned and undertaken by local and central governments. In order to accomplish these plans effectively, it is inevitable to comprehend and summarize the total figure of nutrient dynamics in the lake as well as in the surrounding region. In this study, a mathematical model of nutrient dynamics, which is composed of four segments and 14 compartments in each segment, is presented in order to figure out the roles and relations of each compartment to the nutrient cycles. After the fidelity of the model to field and experimental informations was thoroughly checked, the calibrated model was used to get the future status of water quality of Lake Kasumigaura.
