Abstract
Tank model, one of simple water quantity models, is developed based on the
concept of prototype model in order to simulate water quantity and water quality
in Chikugo River basin. Chikugo River basin, the biggest one in Kyushu Island,
is very famous in Japan for complicate water problems especially between
irrigation water and drinking water etc. Though tank model for water quality
analysis is rarely used in whole watershed, the developed tank model in this
study can effectively simulate COD concentration of Chikugo River as well as
its flow rate. And at the same time, unit COD loading of the existing pollutant
sources is estimated. After calibrating the parameters of the water quantity and
water quality, simulation results revea
