| Outline of Final Research Achievements |
I carried out the river water sampling and chemical analysis in the Sea of Harima-Nada river basin every month and was able to clarify the nutrient characteristics. In addition, I made a generation load analysis using Geographic Information System (GIS) and was able to calculate the generation loads from household and land. Using this result, I showed a reduction effect of the generation load in consideration of a sewerage development area and clarified necessary sewerage treatment efficiency to return the load to the quantity of load in around 1985 when fishery production was the largest. In addition, using an economic evaluation model, I was able to calculate the most suitable risk to evade red tide outbreak and bleach of Nori by comparison of the long-term change of fishery production with the number of outbreak of the red tide.
