Abstract
The main aim of the work was the efficiency evaluation of several water area geophysical survey techniques intended for shallow studies in different geological conditions. The results are based on synthetic data obtained for more than twenty geoelectrical models, typical for rivers of Central and North-Western regions of Russia. During the work, we have considered following survey techniques, where the moving measurement array is supposed to be implemented: high-resolution seismic, electrical resistivity imaging with towed multi-electrode array, controlled source radiomagnetotelluric sounding. Obtained results are important at the stage of planning of real geophysical surveys and can help one to select the measurement technique appropriate for geological structure under investigation.
