P017 Evaluation of Peat layer using geoelectrical methods at Nile Delta Egypt. Gad El-Qady 1 3 Mohamed Metwaly 1 Ahmed El-Galladi 2 and Keisuke Ushijima 3 Abstract 1 A peat layer has been encountered in the subsurface Holocene sediments of eastern part of the Nile delta at depth ranging from 5 to 13 meters and the maximum thickness of 3m. This study aims to investigate the credibility of the available surface geophysical tools in detecting the vertical and lateral extensions of peat layer at two locations in Mansoura city where a considerable thickness of peat is recorded by borings.
