The Runoff Analysis of Total Nitrogen and Phosphorus in a Storm Event in a Forested Basin Using a Tank Model

Abstract

This study focused on the runoff characteristic of total nitrogen and phosphorusduring a storm event in a forested basin. The stream water was separated into four runoff components using a tank model, and the correlation between those components and the temporal changes of stream water concentration of total nitrogen and phosphorus was investigated. It is clarified that stream water concentration of total nitrogen and phosphorus are formed by the temporal change of runoff components. Then, the modeling of runoff of total nitrogen and phosphorus from a forested basin is employed using a tank model.
