Resistivity Modeling of Sinkholes Effects Caused by Karst and Suffosion

Sinkholes caused by two different processes of karst and suffosion have some similarity and both create damages in cities, settlements and single houses in rural areas. Not once the problem was set to give forecast of sinkholes before their output on the earth surface. The authors with the help of mathematical modeling of anomalous effect above vertical cylinder and similar models tried to estimate possibilities of resistivity methods for forecast of dangerous underground sinkholes before their collapse.
