Standalone desktop application for analysis, visualization and interpretation of hydro chemical data
Abstract : Integrating advanced simulation techniques and data analysis tools in a freeware Geographic Information System (GIS) provides a valuable contribution to the management of conjunctive use of groundwater (the world's largest freshwater resource) and surface-water. To this aim, we describe here the FREEWAT (FREE and open source software tools for WATer resource management) platform. FREEWAT is a free and open source, QGIS- integrated interface for planning and management of water resources, with specific attention to groundwater. The FREEWAT platform couples the power of GIS geo-processing and post-processing tools in spatial data analysis with that of process-based simulation models. The FREEWAT environment allows storage of large spatial datasets, data management and visualization, and running of several distributed modelling codes (mainly belonging to the MODFLOW family). It simulates hydrologic and transport processes, and provides a database framework and visualization capabilities for hydrochemical analysis. Examples of real case study applications are provided.
? There likely exists alternative RDBMSs which are faster at reading and writing data.
? The maximum value of the ID column is calculated and a column containing a sequence of ID values greater than the maximum existing values are added to the raw data.
? An effort is being made to store all new data and move all existing data into relational database management systems (RDBMS), commonly referred to as “databases”.
? Modelers may take advantage of integrating advanced hydrological modelling codes within a GIS environment, thus reducing model setup and analysis time, and avoiding data isolation, data integrity problems and broken data flows between model implementation and pre- and post-processing step.
? A synthetic problem was designed to show the application of FMP in FREEWAT as a tool to address water management issues in urban and rural areas.
? In FREEWAT, MODFLOW-OWHM is used to deal with the con-junctive use of ground- and surface-water for water management issues.
• It was not possible to foresee the exact direction that WAVE was going take when the idea was first proposed.
• The DCR also handled the organization of these data files and databases within the DCR’s network. UMass proposed multiple test versions of the application which received feedback from the DCR.
• GitHub is used for many purposes related to WAVE and WAVE development and system processes. The application code is stored on GitHub which offers advanced version control and collaboration features during development.
? There is the opportunity to take advantage of this large mass of data and information to develop dynamically growing and efficient ground water management plans.
? Geographic Information Systems (GISs) have been applied to sup-port environmental modelling and, being able to store, manage/analyse and visualize large temporal, spatial and non-spatial datasets, they are the most efficient tools to deal with geometric and alphanumerical data.
? The interface allows non software programming Users to take advantage of the library features and manage temporal data in the modelling environment.
