Understanding ecologically sensitive wetlands often requires non-invasive methods to characterize their complex structure (e.g., deposit heterogeneity) and hydrogeological parameters porosity hydraulic conductivity). Here, electrical conductivities of a riparian wetland were obtained using frequency domain electromagnetic induction (EMI) methods. The was previously characterized by extensive in...

With the growing population and adverse effects of climate change, pressure on coastal aquifers is increasing, leading to a larger risk saltwater intrusion (SI). SI often complex difficult characterize from well data only. In this context, electrical resistivity tomography (ERT) can provide high-resolution qualitative information lateral vertical distribution salinity. However, quantitative int...

Abstract A denudation-dissolution hilly area about 20km southeast of Jinan city, Shandong Province, China is characterized by karst features. The upper part the covered quaternary Holocene flood and slope deposits, lower bedrock Ordovician limestone, which a moderately weathered massive structure with developed joints fissured fractures, solution grooves can be seen locally. local government to...

This work aims at figuring out the spatial relationships between the geophysical and geological models in a case study pertaining to copper-sulfide mineralization through an integrated 3D analysis of favorable target. The Ghalandar Skarn-Porphyry Cu Deposit, which is located in NW Iran, is selected for this research work. Three geophysical surveys of direct current electrical resistivity and in...

The hyporheic zone (HZ) is a critical area of all river ecosystems. It the beneath stream and adjacent to stream, where surface water groundwater are mixed. HZ extends both vertically laterally depending on sediment configuration, namely their porosity permeability. This influences communities’ structural pattern active dispersal among distinct rivers compartments alluvial aquifers. still diffi...

Renewable energy resources can indisputably minimize the threat of global warming and climate change. However, they are intermittent and need buffer storage to bridge the time-gap between production (off peak) and demand peaks. Based on geologic and geochemical reasons, the North German Basin has a very large capacity for compressed air/gas energy storage CAES in porous saltwater aquifers and s...

Abstract. The warming and subsequent degradation of mountain permafrost within alpine areas represent an important process influencing the stability steep slopes rock faces. unstable monitored Mannen (Møre Romsdal county, southern Norway) Gámanjunni-3 (Troms Finnmark northern were classified as high-risk sites by Norwegian Geological Survey (NGU). Failure initiation has been suggested to be lin...

Monitoring the flow behaviour on the micro-scale is very important in many industrial and biochemical process, the multiphase coexistence in microchannel provides many attractive characteristics compared to a single-phase flow. The precise flow rate control and well-defined channel geometries make it possible for us to make detailed investigation on multiphase flow phenomena on micro scale. Thi...
