Application of Interpolation Methods in ArcGIS for Groundwater Flow Problems

These maps illustrate the application of ArcGIS deterministic and statistical interpolation methods in practical problems of groundwater flow. The methods are used in specific procedures of data preprocessing as well as postprocessing of data calculated by numerical models of groundwater flow. The basic principle in applying interpolation methods rests in creating a continuous distribution of examined variables (e.g., groundwater surface, impermeable layer) based on values of discrete data (e.g., boreholes, nodes of calculation grid) measured in the area of interest. The project addresses mainly interpolation methods included in the ArcGIS 3D Analyst, ArcGIS Spatial Analyst, and ArcGIS Geostatistical Analyst extensions. The project acknowledges the study Analysis of Risks Associated with Groundwater Regime Changes in Extreme Hydrological Situations (Grant Agency of Czech Republic No.103/06/0595).
