AB: Study on extreme flood events has critical limitation of shortage of historical data because modern systematic data don't implement long time series. The historical documentary records hence can be one of the important sources to contribute additional information on extreme flood events which had occurred before the instrumental observations began. For the proper data mining, documentary records satisfying following four conditions are preferred. 1. Long enough time series, 2. Official archives covering over all Korean peninsular, 3. Abundant enough record number, and 4. Detailed damage description. The Annals of Choson Dynasty includes about 500 years and 511 number of flood records during Choson Dynasty in ancient Korea. According to the annals, there were highly dense flood damage records in the middle of 17th century and the largest human damage and residence damage occurred in 1739 and 1856 respectively. Another source is Jeungbo-Munheonbigo. Jeungbo-Munheonbigo is a taxonomic document categorized by the themes such as cultures, social systems, and climates as well as contains 79 number of flood damage records. An effective way to analyze those historical floods without water level data is to classify and categorize the flood damage records because all records are written in descriptive way. Consequently, 556 records are categorized into 10 items by flood damage types and each categorized record is classified into three grades by numerical level that is how much the record is expressed in numerical way. These grouping results are applied to decide reasonable period range to get detailed information from entire inspection period. In addition, Historical Flood Evaluation Index (HFEI) thereby can be derived from the processes in quantitative and statistical ways to evaluate the magnitude of each ancient flood. In this research, flood damage evaluation is mainly focused on the damage of human beings and residences. Also degree ranges based on cumulative probability are induced with two damage inventory. HFEI by conditional weighted factors is applied to every flood record and to analysis for flood distribution in annual series.
