GIS-based assessment and mapping of groundwater source potential in selected aquifers of the Western Carpathians

geospatial assessment tool to calculate the probabilistic relationship
between dependent and independent variables, including
constructing multiple classification maps in a geographic information
system (GIS) environment. A total of 10,465 springs were identified
and mapped in the GIS environment during the research, including
5,302 in the Flysch Belt, 2,832 in the Crystalline complex, 351 in the
Paleogene, and 1,980 in the Older Paleozoic. The effective factors -
slope, aspect, plan curvature, elevation, topographic wetness index
(TWI), stream power index (SPI), slope length (LS), lithology,
distance to rivers, distance to ridge-lines, distance to faults, and
distance to lithological borders - were derived from a spatial
database. Using these effective factors, groundwater spring potential
was calculated using a single model, and the results were plotted in
ArcGIS. The final result indicated that the bivariate statistical index
model (like FR) could be used as a simple tool in the assessment of
groundwater spring potential.
