Detection of Water Accumulation in Weathering Zone Based on Shallow Seismic Methods

Urban expansion entail building roads on a slope of hills where natural drainage path are cut. It may be the reason of natural hazards like subsidence or in drastic cases, slipping whole embankment with the road. Main aim of investigation was to detect average depth of water table in a place where road embankment cut a natural slop of the hill what causes water retention for migrating ground waters from top of the hill. Detection of local saturation zones by seismic imaging is possible when refraction and MASW method are used simultaneously. Water-detectable properties of refraction waves supported by continuous model from MASW seems to be a future of effective water-content zones detection.
