Land Subsidence Monitoring and Analysis in Louisiana Using GNSS Daily Solutionsem (NSRS) has been initiated by the National Geodetic Survey (NGS) to enhance the vertical component of the NSRS in the USA. In addition to the positional coordinates, NSRS combines scale, gravity, orientation, and their variation with time. In this study, we estimate and analyze the land subsidence

Geoelectric Study of the Plio-Quaternary Groundwater in the Tfal Area (Southern Gafsa, Southwestern nisia depends on the captured formations and the nature of the water resources of the aquifers (renewable or ancient). In general, salinity could exceed 4 g/l. These high salinities are mainly due to the dissolution of evaporates and the lithological nature of the aquifers. However, salinities below

3D Seismic Attribute Expression of Subsurface Geological Features: Reefs and Channel Systemslineating the subsurface geological features that were hardly comprehensible using conventional 3D seismic amplitude volumes. This study shows how the subtle patch-reefs and the complex meandering channel system, which were not initially well-defined in conventional seismic volumes, appear on differ
