　View Summary

In the Kinokawa river basin, as same as other watersheds around the world, excess runoff of nutrients to the ocean mainly due to human activities has become an environmental issue. This study conducted high-frequency total nitrogen (TN) and total phosphorus (TP) monitoring at several monitoring posts set downstream of the Kinokawa river in the Kii peninsula, Japan in order to evaluate water pollutant load from the basin quantitatively. The water sampling has been conducted about 90 times for over a year from May in 2018 at the monitoring posts. In the calm or the drought periods, TN and TP concentrations at Kinokawa river mouth were basically about 0.8 similar to 1.1 mg/L and under 0.05 mg/L, respectively. However, TN concentrations was exceeded 5.0 mg/L after one of the most intense storms, it was shown the TN concentration had a tendency extremely to rise rapidly in flooding condition. This tendency was similar in TP. The result of pollutant load analysis showed that 65% of the nitrogen load and 80 % of the phosphorus load from the basin was generated during a few and heavy flooding which were included in 5 % flow exceedance probability. These results imply it is essential that to understand and to predict how nutrients runoff in short-term during flooding events in order to accurately grasp long-term nutrient runoff amount.

　View Summary

 In order to support planning of disaster waste disposal, a numerical model simulating disaster waste transportation and disposal was developed. The proposed model tracks the movement of disaster waste between originating region, temporary storage areas and final disposal site. A crushing/classification process at temporary storage areas, Number of vehicle as a carrier, transit route, a capacity of temporary storage areas and final disposal site are freely settable in the model. The model was applied for a city in Mie prefecture aiming at evaluating of actual disaster waste disposal plan at the time of the occurrence of Nankai Trough earthquake. The result of simulation indicated that a number of crushing/classification equipment and workers were required in order to execute disaster waste disposal.

　View Summary

 HYPE(hydrological predictions for the environment) model was applied for Kinokawa river basin in order to evaluate an applicability of HYPE for Japanese watershed. Firstly, a fundamental HYPE in Kinokawa was constructed by using landuse, soil, topology information based on Swedish HYPE. Secondly, a calibration based on Markov Chain Monte Carlo method was performed in order to improve prediction accuracy of Kinokawa river flow rate. Then, point and non-point sources of nitrogen and phosphorus were implemented aming at runoff analysis. According to the comparison of simulated and observed nutrient load, it was shown that the accuracy of nutrient load predicted by HYPE was reasonable. In conclusion, it was suggested that HYPE was available for Japanese watershed aiming at water and nutrient runoff analysis.

　View Summary

Throughout Japan, disaster-preparedness maps have been made by the method of town-walk. This method improves disaster-preparedness and allows for a greater understanding of the area. The making of disaster-preparedness maps increases the disaster awareness of the participants. Further, the involvement improves participants' ability of self-help and increases cooperation in local communities. Currently, there is a system to support the making of conventional disaster-preparedness maps, but no support system for maps made using the town-walk method. Therefore, we have proposed and developed an integrated support system for the making of disaster-preparedness maps by gathering information from the town-walk. We conducted a comparison experiment between the proposed system and the conventional system (using paper maps). This experiment demonstrated that a consistent support function would be effective in developing disaster-preparedness maps using the town-walk method. We also confirmed that the proposed system influences the improvement of disaster-preparedness awareness, the understanding of the area, and the conventional system.

　View Summary

The off-flavor taste of tap water due to 2-methylisoborneol (2-MIB) is caused by blue-green algae. This is one of the water quality problems associated with high nutrient loads, such as those found in the Kinokawa River, with drains the southwestern part of the Kii peninsula in Japan. Water quality monitoring data showed that 2-MIB tended to increase when total phosphorus (TP) concentration exceeded 0.02 mg/L. This study employed mass load and river water quality analyses coupled with water runoff analyses to examine ways of mitigating TP load in river water. In this study, it was revealed following things. (1) TP mass load could be reduced by approximately half if the industrial drainage volume standards defined in the Water Pollution Control Law were more stringent. (2) TP concentration could be decreased by 41% in response to TP mass load reduction and by 5% in response to an increase in river flow rate. (3) TP mass load reduction combined with an increase in river flow rate could reduce TP concentration to less than 0.015 mg/L and prevent increases in 2-MIB in tap water.
