This study aims to determine the modulus of elasticity for surface soilin Al-Hilla city in two modes (dynamic and static) using two methods, namely the engineering method and the geophysical method. Theengineering method included conducting well survey in two ways that arecross-hole and down hole, while the geophysical method includedconducting some geotechnical tests in the studied area to calculate thevelocity of seismic waves and some geotechnical properties.Six wells have used in the study area; four of them were used forengineering purposes at a depth of more than 10 meters. While, theremaining two wells utilized for well seismic survey, where longitudinaland transverse wave velocities calculated between these two wells, one ofthem considered a source and the other is at a distance 6.7 m away forreceiving at the same depth, an ABEM Terralloc Mark6 recorder was usedto record data in the field.The first time down captured to interpret all the recorded informationof the two methods and for all depths. In addition, the speeds of thelongitudinal and transverse waves calculated up to a depth of 10 meters.
