Abstract:
In this study, a database based on the geo-information system (GIS) was developed for the debris flow hazard assessment of expressways in South Korea. The debris flow assessment method developed by the Korea Expressway Corporation (KEC) was used for estimating the debris flow hazard grade and for building the database schema. PostgreSQL was selected as a database management system, and PostGIS was used to process the spatial data. The primary information (e.g., expressway, rainfall, digital numerical map, processed information) assess using the KEC method can be standardized and stored in the constructed database. So far, the database was established based on the expressway and debris flow hazard information of 4,478 points along the 22 expressways in South Korea.
