Spatial decision support system for abandoned coal mine reclamation.Abandoned coal mines and mining activities typically cause severe environmental problems related to erosion and pollutant transportation.Because of the lack of data integration,traditional methods and procedures of reclamation plan design must go through a time-consuming process.As new technologies from a variety of fields have been revolutionizing the way in which planning is conducted,it is practical to find a more efficient approach to deal with complex reclamation planning.In this research,a Geographic Information System(GIS),remotely sensed data,erosion modeling,and Multi-Criteria Decision Making(MCDM)methods were integrated to implement a Spatial Decision Support System(SDSS)for better reclamation planning.The newly developed Open Development Environment(ODE)and GIS componentware technology were adopted to provide GIS functions and to build the interface.The system was designed to facilitate the prioritizing of specific areas for reclamation within a region of abandoned coal mines.
Urban Flash Flood Risk Assessment and Inundation Model Utilizing GIS for Terre Haute, IndianaUse of ArcGIS to examine flash flooding variables and produce a flash flood risk assessment and inundation model for Terre Haute, Indiana. Risk assessment, produced within ArcGIS, indicates that an increase in developed area leads to an increase in very high flash flood risk area and majority of very high risk area resides in developed areas of Terre Haute. Inundation model, produced using ArcGIS and Python, indicates that the proposed model can determine locations of flash flooding, but spatial extent of model predicted flooding is not reliable based on field validation.
