    Hi,

    This is kaustubh lawekar from mumbai, India. Have read about you a lot and about your techniques which are successful in finding underground water. Here in India there are so many villages that need this kind of technology to locate underground water tables and use them for making borewells for drinking purposes. Hence have approached you if you could hepl me out regarding this. Awaiting a favourable response…

    Thanks for contacting us. More the details of that work currently resides in a thesis (http://www.geo.mtu.edu/rs4hazards/Project%20resources/theses/JNBruning_Thesis_ETD.pdf) or you can view a shorter version as a powerpoint presentation (http://www.geo.mtu.edu/rs4hazards/Project%20resources/Conference%20presentations/Bruning_ASPRS.pdf).

    The focus of this work has been to identify fracture zones using satellite imagery with the hopes that these fracture zones are more likely to produce water at sustainable rates for communities. This approach is aimed at hard-rock terrains, where groundwater flows tend to concentrate in subsurface discontinuities that occur with faulting and bedding and changes in rock types, etc.

    A major challenge we had with our work in central Nicaragua was the human influence on the landscape, which falsely suggested geological faults, and the extent of weathering of the surface, which tended to disguise the presence of the faulting.

    We have been enhancing and testing our approaches at in areas less weathered and affected by humans around Quito, Ecuador, and that work is ongoing. Here is a brief presentation of this work at: http://mtu.na4.acrobat.com/p79407098/ and an overview of our study plans at: http://www.geo.mtu.edu/rs4hazards/Project%20resources/PIRE%20student%20presentations/rios_sanchez_pire_mtng_11_13_09.pdf

    If you have questions, you might send me more information on the geology of the areas of your interest.
