Seeking to analyse the groundwater potential of an area, but the resistivity survey is not possible there. Will anybody tell some alternate instrument?
I do not understand exactly: Why it is not possible to do a resistivity research. Is the terrain inaccessible? Or makes the method no sense? Maybe you can use Electromagnetic conductivity (EM) or ground penetrating radar (not very deep), but you also need accessibility.
You can use satellite images and topography in text format. Then use Rivertool software for basin analysis. Use subsurface data and integrate them. More you can find from my papers:
do you mean only surface based measurements or also including borehole tests? Best you would describe your aquifer - lithology, depth, area, climate, etc. It really depends on these factors which approaches are promising. Shallow alluvium and deep karst are almost incomparable...
I have used cross-well seismic and 2D reflection seismic for delineate flow units in a proposed aquifer storage and recovery horizon. It is a carbonate aquifer in southern FLorida. I have several publications that you can access on my page assigned by ResearchGate
