Abstract

South Korea is a maritime nation, surrounded by water on three sides; hence, it is important to preserve in a
sustainable manner. Most areas, especially those bordering the East Sea, have been suffering from severe coastal
erosion. Information on the sediment yield of a river basin is an important requirement for water resources
development and management. In Korea, data on suspended sediment yield are limited owing to a lack of logistic
support for systematic sediment sampling activities. This paper presents an integrated approach to estimate the
sediment yield for ungauged coastal basins by using a soil erosion model and a sediment delivery rate model in a
geographic information system (GIS)-based platform. For applying the sediment yield model, a basin specific
parameter was validated on the basis of field data, that, ranging from 0.6 to 1.2 for the 19 gauging stations. The
calculated specific sediment yield ranged from 17 to 181 t/km2.yr in the various basin sizes of Korea. We obtained
reasonable sediment yield values when comparing the measured data trends around the world with those in Korean
basins.
