A review of coupled groundwater and heat transfer theory is followed by an introduction to geothermal measurement techniques. Thereafter, temperaturedepth profiles (geotherms) and heat discharge at springs to infer hydraulic parameters and processes are discussed. Several studies included in this review state that minimum permeabilities of approximately 5×10<kmin <10 m are required to observe a...

During in situ remediation of contaminated groundwater, a treatment solution is often injected into the contaminated region to initiate reactions that degrade the contaminant. Degradation reactions only occur where the treatment solution and the contaminated groundwater are close enough that mixing will bring them together. Degradation is enhanced when the treatment solution is spread into the ...

It is suggested that in a localized remnant of Kalahari sand at Dufuya, central Zimbabwe, groundwater flows in an integrated pattern inherited from the paleochannel network of the underlying gneiss. Contact springs occur at discrete localities along the Kalahari sand/gneiss boundary and are associated with spring sapping and land surface subsidence. Subsidence is presumed to be due to preferent...

Land reclamation has played a significant role in the urban development process in coastal areas in many countries. Over the last 20 years, land reclamation has gained much popularity especially along coastal areas of the south and east China due to rapid development of industry and urbanization. While reclamation provides valuable land, it also creates various engineering, environmental and ec...

[1] Based on a literature overview, this paper summarizes the impact and legacy of the contributions of Wilfried Brutsaert and Jean-Yves Parlange (Cornell University) with respect to the current state-of-the-art understanding in hydraulic groundwater theory. Forming the basis of many applications in catchment hydrology, ranging from drought flow analysis to surface water-groundwater interaction...

The consumption of groundwater polluted by arsenic (As) has a severe and adverse effect on human health, particularly where, as happens in parts of SE Asia, groundwater is supplied largely from fluvial/deltaic aquifers. The lateral distribution of the As-pollution in such aquifers is heterogeneous. The cause of the heterogeneity is obscure. The location and severity of the As-pollution is there...

Surface and groundwater dynamic interaction in the Upper Great Chaophraya Plain of Thailand is explored. The surface-soil water model SWAT and the groundwater model MODFLOW are semi-coupled to determine the various hydrological components and their relevant flow behaviour. The coupled models are executed by running the simulations individually using the monthly river-groundwater interactions an...

This paper describes an application of EnSym (Environmental SystemsModelling Platform) to assess the impacts of climate change on the groundwater levels in Victoria. EnSym is a modular and user-friendly software platform to facilitate the use of environmental modelling tools. It enables easy and rapid evaluation of environmental outcomes due to changes in land management and climatic conditions...
