Development of GIS-Based Database and Vulnerability Analysis Tools for Mississippi Groundwater, Surface Water, and Dams
The development of a GIS-based database, or geodatabase, for the purposes of creating a state-wide inventory of groundwater, surface water and dam resources in Mississippi has been undertaken. The database supports the development of vulnerability assessments for these resources based on their susceptibility to natural and anthropogenic threats. This investigation requires the integration of a variety of datasets (e.g., elevation, hydrology, dams, geology, soils, population, transportation, etc.), made available by federal and state government agencies, into a SQL Server enterprise geodatabase. The project data model leverages from existing ArcGIS data models, including ArcHydro and NHDinGeo, for the development of a scale-independent geodatabase to support vulnerability assessment tools. ArcGIS ModelBuilder is used in conjunction with custom designed Graphical User Interfaces (GUIs) in the construction of an ArcGIS Desktop toolbox. The custom tools automate the development and manipulation of model inputs, evaluation of outputs, maintenance of the project geodatabase, the development and evaluation of models and model scenarios, and the implementation of vulnerability assessments. The geodatabase data model and tools are flexible and scaleable, allowing for the user to update, define and refine models and model input parameters.
