ABSTRACT An underground structure called a siphon allows irrigation of water canals and channels to pass underneath water drains. Three groups of loads that may have an impact on the siphon’s Geotechnical stability are: (1) loads brought about by traffic and truck duties on bridges; (2) loads brought about by drain water on the siphon’s body; and (3) loads brought about by irrigation channels and the dynamic movement of sandals and bots. To address the problem, surveying was done to see if the body of the submerged Syphon had any deformations. A ground penetrating radar study of the research area will be used to pinpoint the exact location of the damaged parts and the areas of deformation in the body of the submerged Syphon. On the southwesterly side (the exit), three GPR profiles were made, and on the northeastern side (the mouth), five. To display the covered drainage body’s infrastructure, the measured GPR data were processed differently. Deformities and distortion areas in the body of the submerged siphon were discovered at various places and depths on the two sides of the siphon after the processed data were analyzed.

ABSTRACT Egypt’s southern region has significant economic and historical importance. However, due to the lack of data, this area has not gotten sufficient geodynamic research. Minor, to moderate earthquake activity along tectonic structures originating in the region from several faults is felt in southern Egypt. The study’s geographical scope includes the Red Sea coast, the Eastern Desert, the Western Desert, Aswan, and Nasser Lake, and it lies between 22° and 27° 30 N and 25° to 34° E. In this paper, the crustal deformation and earthquake events in the southern part of Egypt have been studied. The Global Navigation Satellite System (GNSS) observations taken by Egyptian Permanent Geodetic Network (EPGN) have been processed and adjusted for the period 2010–2019 using Bernese v.5.2 software. In addition, we investigate the source mechanism of the significant earthquakes ≥3 magnitudes using the waveform data recorded by the Egyptian National Seismic Network (ENSN) during the period 2012–2019. The focal mechanisms of these earthquakes were constructed with high reliability based on the P-wave first motion polarities. The results show that the average residual velocity concerning Nubian fixed is about 0.5 ± 0.25 mm in the east direction and 1 ± 0.3 mm in the north direction.
