Abstract: Remote sensing data can be integrated with
analyses of topography, structural geology, hydrogeology
and geophysics. The integration gives premises for the
delineation of zones of potential groundwater resources in
strongly fractured and karstified deep aquifers in the
uplifted Meo Vac Highland, northern Vietnam. Remote
sensing analysis outlines geological faults with hydrogeological
significance. These faults are combined with a
derived lineament density map, interpreted analysis of
surface flow direction and existing hydrogeological data,
resulting in indications of groundwater flow direction. An
analysis of the SPOT 5 band ratio 4/1, together with
indications of surface-flow direction in low terrains,
results in a determination of underground cavern passages.
The delineated zones of potential groundwater resources
are verified by detailed hydrogeological field surveys and
geophysical measurements. Remote sensing analysis is
shown to effectively contribute to the investigation of
groundwater resources for a hydrogeologically complex
