Abstract
Accidents in agricultural reservoirs continue to occur due to heavy rain caused by abnormal weather conditions. To prevent reservoir accidents, it is necessary to identify factors affecting collapse and manage them safely through prior inspection and repair. For reservoirs with a total storage capacity of less than 50,000㎥, which accounts for 81% of reservoirs nationwide, regular inspections conducted at least once a quarter are the only safety inspection procedures, and the conduct of regular inspections can be seen as a measure of safety inspections. As a result of the survey, it was determined that the implementation status of regular inspection was low at 46%, and problems were analyzed and improvement measures were proposed. Additionally, if the factor affecting collapse is a member with a low score, it is difficult to reflect the results of regular inspection in the safety grade. In this study, we analyzed the problems with the regular inspection grading system and proposed an improvement plan by borrowing and applying the condition evaluation method of precise safety diagnosis, assessing overflow risk, and considering downstream impacts.
