| Outline of Final Research Achievements |
The main objective of this study is to develop and validate the basin scale simulation model to simulate and evaluate the behavior of rice pesticides in the watershed containing paddy rice field in order to be used in the environmental impact assessment and registration/regulations of pesticides. In studies performed in 2012 fiscal year and the 2013 fiscal year , the construction of the model system for simulating pesticide behavior in rice paddy for the basin scale (PCPF-1 @ SWAT) was first carried out. A basin scale material circulation model (SWAT model) developed by the United States, Department of Agriculture, Agricultural Research Service were used as a base model to plug in the pesticide fate and transport model (PCPF-1), previously developed by the principal investigator. The new model (PCPF-1@SWAT) was first verified using a monitoring survey data in Ibaraki Prefecture, Sakuragawa basin and then with the data set obtained in the Sacramento River basin in California.
