Abstract
This study aimed to develop a prediction model for water quality (concentration of total nitrogen, total phosphorous, and chemical oxygen demand) , which is applicable to wide range of scenarios, and has a simple framework for using municipal administration persons without requiring excessively high mathematical precision. The model was developed for 26 watersheds that flow into the Seto Inland Sea in Kagawa Prefecture. Developing the model, border of watersheds obtained from GIS, public water quality data for 6 years, and data of land use ratio (paddy, upland, forest, urban, and inland water) were used. As a result, the model was developed which predicts water quality in estuaries with ±20% of difference with measurement values, and has data of land use ratio as variables, and parameters for the model was obtained.
