The Study Of The Pollutant Transport Process For Accidental Mass Release In Huaihe River

Water quality numerical simulation as an effective way to understand thesituation and development of the water environment plays an important role in rivermanagement and protection. Due to its time-consuming short, save money andresources, and repeatable calculation condition is easy to control, etc, the numericalsimulation technology in environmental protection and management of river watercan be widely used.This article,which is so as to study the pollutant transport process forAccidental Mass Release in Huaihe River, Taking Huaihe River from Lu Taizi toFeng Tai for example,has introduced the two-dimensional hydrodynamic moduleRMA2and water quality module RMA4,rates the parameters of models to get theappropriate parameters of the hydrodynamic models and the water qualitymodels.On this basis,this paper mainly studies the pollutant transport process forAccidental Mass Release,Which Mainly Includes:(1) analysises the crosswisePollutant Transport process under different time;(2) studys the crosswise PollutantTransport process under different selected sections;(3)analysises the crosswisePollutant Transport law Based on different flow and pollutant concentrationratio;(4)studys the longitudinal Pollutant Transport process for the mainstream ofHuaihe River.In addition,the water environment capacity is calculated in thispape.This can laid the foundation for the pollution simulation and prediction ofHuaihe River.
