Use of Nonofficial Intermittent Waterfall Occurrence Data for the Validation of an Infiltration Model for Volcanic Jeju Island, Korea

This study attempts to validate an infiltration model, the Soil Conservation Service–Curve Number (SCS–CN) method, using nonofficial intermittent occurrence data of Eongtto Falls on Jeju Island, Korea. Simply due limited official continuous runoff concerning validation a newly set SCS-CN method for Island was practically impossible. Instead, this tries use purpose. focuses Falls, which is one most famous tourist attractions island. Various records can be collected from newspapers, personal homepages, and various social networking services. The is, in study, used check if effective rainfall occurs or not. In fact, approach quite as streams are fully dry during non-rain periods. Evaluation based analysis contingency table, measures consistency events waterfall records. Additionally, quantify results some such accuracy, hit ratio, false alarm ratio used. carried out all 2011 2019, derived confirm that far better than conventional thus far.
