The application of the MODHMS in contaminant transport simulation

With the development of the economy and rapid population growth, the range of contaminated groundwater is getting bigger and bigger. Groundwater pollution has a slow process, and it is not easy to find and difficult to control. Once polluted, it takes more than ten years, sometimes even decades to recover. Groundwater pollution has a close relationship with people´s health. This paper mainly discusses the range of contaminant transport in different time of groundwater in the MODHMS model. MODHMS is a fully integrated surface/groundwater flow code. The Guishui River is selected as the study area, and the major involved research methods and key technologies are discussed briefly. Analysis shows that the MODHMS is an effective tool to simulate the contaminant transport of groundwater; it provides a more feasible idea to predict and control the groundwater quality.
