Abstract

A difficulty has risen in estimation of non-point source load of large-or medium-scale watershed in China owing to shortage of observation data. Aiming at this issue, this paper presents a new method based on the in-situ data available from hydrological stations and a calculation model. This model considers various factors of land use and hydrological geographical conditions, etc. and adopts hydrograph division and mathematical optimization methods for model calibration. It was applied to the Tieling reach of Liao river and achieved an accuracy of 15% in comparison with the pollution data surveyed in 2009. As a method based on abundant hydrological data, it is easy to implement on computer for a quick calculation and analysis of nonpoint pollution.
