AB: This study presents an application of GIS-based hydrological modeling and spatial analysis to a coal mining site to effectively control the contaminated surface runoff for mine reclamation. A reliable DEM (Digital Elevation Model) was generated at the study area by detailed topographical surveys. Hydrological analyses were performed to extract the characteristics of drainage system such as flow direction, flow accumulation and catchment area from DEM. The results of spatial analysis showed that some runoff drained through waste dump can flow in the river without any purification. Consequently, several practical actions were suggested to optimize the design of drainage system in the study area for mine reclamation.
