Groundwater preservation comprises a major problem in water policy. The comprehension of the groundwater/hydraulic systems
can provide the means to approach this problem. Generally, drilling is expensive and time-consuming. On the other hand, new
techniques have been applied during the last few decades that provide useful information on the depth and quality of aquifers.
Among them, transient electromagnetic method (TEM) is an appealing method that provides fast results with minimum field crew
and solves several hydrogeological problems. Many portable systems for single-site measurements are commercially available.
The TEM-Fast 48HPC was used for acquiring 106 soundings in the northwestern Crete in Greece for defining the hydrogeological
characteristics of the study area, since there were no available data from boreholes. Detailed geological, hydrolithological
and tectonic survey was applied prior to the geophysical measurements. All the data were integrated to produce a secure and
reliable hydrogeological model for the study area prior to any future hydrowell. Specifically, geometrical and hydraulic data
of the study area groundwater were acquired. Two unconnected aquifers were detected and their possible contamination due to
saltwater intrusion was analyzed and eliminated. Moreover, a location for borehole construction and groundwater pumping based
on the potential of the aquifer system was proposed. Finally, the contribution of TEM (and electrical resistivity tomography)
geophysical methods in studying complex coastal aquifers is shown by this work. 相似文献

Effective management of groundwater resources is a well-known problem in several areas around the world. It is especially important to areas suffering from an intrinsic lack of fresh water, such as islands. Detailed study of available aquifers is of particular interest in the highly touristic Greek island of Crete. The increasing water demand makes water resources management extremely important for sustainable development. This is the case in the prefecture of Chania in Western Crete, where there has been a lack of success of many different groundwater management plans that have been produced over the years and submitted for application to water management authority. The inefficiency of the management plans is verified by the continuous water shortage reported every year which forces the public authorities to transfer water from far away sources and wells. Until today there are only geological data as well as information from the borehole logs; therefore, the current work is focused to study in detail the tectonic and hydrogeological characteristics of the Keritis watershed to make a correlation of the available geoenvironmental information with the geophysical data of the study aquifer. Transient electromagnetic soundings were conducted to obtain detailed information about: the tectonic, hydrogeological, hydrolithological, and geometrical characteristics of the aquifer under investigation. In addition, optimum areas of water well drilling were identified to minimize the uncertainty and the total cost (economical, managerial, etc.) of future groundwater surveys. 相似文献
