The aim of this research is to investigate the terrain deformation in the metropolitan area of Sydney using multiple satellite radar imagery. The persistent scatterer interferometry (PSI) strategy developed at Geodesy and Earth Observing Systems Group (GEOS) of the University of New South Wales (UNSW) is used to map the land deformation in Sydney with C-band ENVISAT radar images in this study. ...

Groundwater is an important source of drinking water in coastal regions with predominantly unconsolidated sediments. To protect and manage extraction wells these regions, reliable estimates groundwater flow velocities around well fields are paramount importance. Such measurements help to identify the dynamics its response stresses, optimize resources management, calibrate models. In this articl...

A quantitative understanding of the transport of pollutants in groundwater is of great importance from the environmental perspective. Some environmental pollution scenarios involving groundwater contamination are very real. For example, one may encounter a situation where an underground storage tank is leaking hydrocarbons into an aquifer at a constant rate. Similarly, an overturned oil tanker ...

Curium was produced for experimental programs for use as a heat source for isotopic electrical power generators and by 1968 approximately 5 kg had been produced at the Savannah River Site (SRS). Size fractionated groundwater samples were collected near a disposal basin in F-Area at SRS in 1998 and in 2004. Separation of Cm via extraction chromatographic methods was followed by alpha spectrometr...

Traditionally, surface and ground water resources have been managed as separate resources in Australia, with the result that interactions between the two components have not been duly considered in the development of management strategies. A more integrated approach is required to evaluate the impacts of groundwater extraction on streamflow regime, and eliminate the potential for over-allocatio...

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...

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...

Abstract In the early 1800s, a water conflict occurred in community named Fukuzuka Ring Levee on Noubi Plain, Japan. Upper villages required artesian wells for irrigation and domestic uses, but lower did not welcome them because drainage from caused impoundment damage to their paddy fields. The Kabu-ido system was set of rules, including regulation number per village, introduced de-escalate con...
