In the recent decade Poland was repeatedly affected with severe droughts that caused significant losses in the agricultural sector. To minimize the effects of hydrological drought and rationalize the management of water for agricultural purposes, a continuous monitoring of ground water should be implemented country-wide. Such a monitoring network already exists in Poland – State Groundwater Monitoring, based upon direct measurements, however its density and temporal resolution is too coarse to effectively inform about the levels of groundwater and its availability for agriculture. The existing monitoring network can be supplemented with various remote geophysical methods, allowing wide-area estimations on groundwater availability. This publication aims at screening available geophysical methods and their suitability for assessing groundwater levels and stocks.
