Abstract. The current state of research about ancient settlements within the Nile Delta allows hypothesizing fluvial connections to all over Delta. Previous studies suggest a larger branch close Kom el-Gir, an settlement hill in northwestern To contribute new knowledge this little-known site and prove hypothesis, study aims at using small-scale paleogeographic investigations reconstruct channel...

Dam leakage is a major problem in earth-filled reservoir dams. The present research aimed at detecting the seepage zones an dam vicinity of Sarobi village, North Waziristan, Pakistan. objective was achieved by integrating geological, geotechnical, and geophysical datasets. Geological survey carried out area to identify surface exposures. Geotechnical data involved used estimation permeability L...

Abstract. Sea level rise and coastal erosion have inundated large areas of Arctic permafrost. Submergence by warm saline waters increases the rate permafrost thaw compared to sub-aerial thawing on land. Studying contact between unfrozen frozen sediments below seabed, also known as ice-bearing table (IBPT), provides valuable information understand evolution sub-aquatic permafrost, which is key i...

Recent cases of dam failures indicate that the safe operation and proactive maintenance critical infrastructure is significant importance considering growing number ageing dams increase in intensity frequency extreme climatic events. The current procedures to assess performance infrastructure, usually based on geodetic geotechnical instrumentation, do not provide repeatable reliable information...

Topusko is the second warmest natural thermal water spring area in Croatia, located at southwest edge of Pannonian Basin System. Due to favourable geothermal properties, these waters have been used for heating and health recreational tourism since 1980s. Thermal springs with temperatures up 50 °C are final part an intermediate-scale hydrothermal system. However, systematic research on has not c...

S U M M A R Y The solution appraisal component of the inverse problem involves investigation of the relationship between our estimated model and the actual model. However, full appraisal is difficult for large 3-D problems such as electrical resistivity tomography (ERT). We tackle the appraisal problem for 3-D ERT via the point-spread functions (PSFs) of the linearized resolution matrix. The PS...

An integrated geophysical survey using both the electrical resistivity tomography (ERT) and groundpenetrating radar (GPR) methods was undertaken over a cave of great archaeological interest in southern Italy. The survey was performed to assess the stability of the carbonate rock roof of the cave. A geophysical survey was preferred to boreholes and geotechnical tests, in order to avoid the risk ...

Purpose. The research purpose is to apply an original combined approach the study of landslide occurrence in Tarzoust region, based on geophysical approaches. This extremely important because landslides damage roads and buildings many parts North Africa, especially city Tarzoust, NE Algeria. Significant slope failures have resulted serious disasters region. Methods. In this we use Vertical Elec...
