“…An electrical resistivity survey can map three potential targets in the geoectric nature which can be interpreted in the analogues hydrogeological parameters which are porosity, pore uid conductivity and clay contents, all of which are relevant in characterizing streambeds or lake beds [Toran, 2019]. Surveys on stream or lake bottoms help reveal heterogeneity of uvial and lacustrine sediments and the impact on groundwatersurface water interaction [Mitchell et al, 2008]. Distinguished.…”

Groundwater interaction with the surface topological features are interactive based on the internal flow movement and the directions. Parameters such as transmissivities conducti vies and permittivity’s govern the near surface point seepages which leads the near surface topological features in the form of the sharp vegetations and creeks. The movement of the water may be dictated by the slopes, soil porosity, soil drainage and the membrane of the rocks that lie within the aquifer and the adjacent zones. The inner water movement draws vegetation features which may be visible and significant on the satellite imagery in the form of the sharp boundaries, geological areas and the dikes. Ground water exploration works has been carried out in the Village of Nubutautau within Fiji through the detection of underground aquifers with the usage of the Geophysical techniques. An interesting feature of the water zones with the near surface topological feature has been observed.

Rock glaciers are slowly flowing mixtures of debris and ice occurring in mountains. They can represent a reservoir of water, and melting ice inside them can affect surface water hydrochemistry. Investigating the interactions between rock glaciers and water bodies is therefore necessary to better understand these mechanisms. With this goal, we elucidate the hydrology and structural setting of a rock glacier–marginal pond system, providing new insights into the mechanisms linking active rock glaciers and impounded surface waters. This was achieved through the integration of waterborne geophysical techniques (ground penetrating radar, electrical resistivity tomography and self‐potentials) and heat tracing. Results of these surveys showed that rock glacier advance has progressively filled the valley depression where the pond is located, creating a dam that could have modified the level of impounded water. A sub‐surface hydrological window connecting the rock glacier to the pond was also detected, where an inflow of cold and mineralised underground waters from the rock glacier was observed. Here, greater water contribution from the rock glacier occurred following intense precipitation events during the ice‐free season, with concomitant increasing electrical conductivity values. The outflowing dynamic of the pond is dominated by a sub‐surface seepage where a minor fault zone in bedrock was found, characterised by altered and highly‐fractured rocks. The applied approach is evaluated here as a suitable technique for investigating logistically‐complex hydrological settings which could be possibly transferred to wider scales of investigation.
