Application of MapGIS in Groundwater Solute Transport of Power Plants

This paper analyses the impact of unexpected diesel tank leak in the non-normal conditions on groundwater, on the basis of a detailed analysis of hydrogeological conditions of a power plant, using the analytical method of solute transport in groundwater,combining with the DTM module of MapGIS spatial analysis. The results show that if leakage of diesel tank lasts 5 years, the maximum influence range of pollution halo is 0.204 km2 and the farthest impact distance is 660m.
