A research group at Okayama University conducted a questionnaire survey of households in Mabi-cho, Kurashiki City, who experienced flooding due to heavy rains in July 30, and analyzed the discharge behavior of cleanup waste after the disaster.
In recent years, in the case of floods that occur frequently in various places, the garbage is discharged all at once immediately after the inundation, and as a result, garbage is piled up in various parts of the town, and long lines of trucks are seen to be carried into the temporary storage area.In order for the local government to formulate an appropriate initial response to disaster waste, it is necessary to know what kind of waste is discharged from the disaster-stricken house at what timing, but such basic information is lacking. rice field.
Therefore, in this study, we conducted a questionnaire survey of 30 households that experienced flooding in Mabi-cho, which was damaged by the heavy rain in July 7. We obtained and analyzed responses such as recognition and reasons for emission.As a result, discharge patterns were found for 800 types of waste according to the inundation depth of the damaged houses, and the behavior patterns of the dischargers after the disaster were clarified.In addition, illegal storage will occur because the discharge rules are not well known, and even if the discharge rules are known, collection is delayed and it takes time to bring them into the temporary storage site. I also understood that.
From this research, it is possible to predict changes in the amount of waste discharged from the maximum inundation depth in the disaster area. It will be useful in considering the collection plan.
In addition, the researchers say that by conducting similar surveys in other disaster-stricken areas, the discharge behavior of disaster victims will become clearer and the accuracy of flood waste emission prediction will improve, and flood damage in local governments will be improved. It is expected to contribute to the planning of waste measures.
