Soil piping is a complex mechanism of subsurface soil erosion, which results underground conduits (cave/tunnel) varying dimensions. associates with severe consequences, such as land subsidence and slide. Therefore, the investigation pipe crucial. However, study challenging unless characteristic surficial evidences are available. Based on evidences, can be configured geophysical techniques in-tu...
The east Delta horizontal expansion reclamation project is one of the Egyptian reclamation projects which was implemented in 1981. The project area is approximately equal to 366,500 Feddans. It's located in Ismalia Governorate at kilo 96.5 Cairo-Ismalia road. The irrigation system in this project depends on pumping stations at the right bank of Ismalia Canal through pipelines. The pipelines wer...
This study provides an example of fault structure delineation using both geophysical measurements and soil-gas surveys. Seismic refraction and electrical resistivity tomography investigations were performed in com-bination with Direct Push (DP) soil gas concentration measurements, with the main objective being the char-acterization of an assumed permeable fault structure which is covered by sed...
