The long-term settlement of calcareous sand foundations caused by daily periodic fluctuations has become a significant geological hazard, but effective monitoring tools to capture the deformation profiles are still rarely reported. In this study, laboratory model test and an in situ were conducted. An optical frequency domain reflectometer (OFDR) with high spatial resolution (1 mm) accuracy (±1...

Groundwater irrigation has been instrumental in enhancing food security and, arguably, in mitigating poverty in developing countries. Groundwater provides timely irrigation, leading to an increase in crop intensity and productivity (Food and Agriculture Organization 2003). But groundwater irrigation also contributes the most to the depletion of groundwater reserves. Countries with significant g...

Observations of summer microthermal temperature variations suggest, next to hydrological factors, a significant influence plant activity on groundwater flow in fractured claystone materials. Variations microtemperature were compared meteorological parameters and electrical potential plants. With an increase surface temperature, relative air humidity decreases tree potential, measured as the dif...

Groundwater from the coastal aquifers north of Chennai is being pumped since 1981 to meet the increasing demand. Huge groundwater extracting in the coastal aquifers groundwater causes lowering of groundwater table which led to seawater intrusion. The objective of this study is to assess the behavior of this aquifer to seawater intrusion under different hydrological stresses by groundwater model...
