Centrifugal multi-stage pumps for harsh downhole environments

The IAH invite all members and interested parties to attend a presentation designed to provide a high level introduction to  centrifugal pumping technologies, detailing a number of specific case studies where deployment of such systems in Australia, New Zealand and Papua New Guinea has provided enhanced performance, improved reliability and extended runlife in some of the most challenging applications.

New Australian groundwater modelling guidelines

In a subject near to my heart, new Australian groundwater modelling guidelines have been released.  They were prepared by Sinclair Knight Merz and a committee from the National Centre for Groundwater Research and Training — most of the committee are IAH members.

The Waterlines report comments:

“[The guidelines] highlight the development of updated guidelines that promote a consistent and sound approach to groundwater flow and solute transport models in Australia. The guidelines are a point of reference, not a rigid standard and seek to provide direction and the scope and approaches common to modelling projects. Continue Reading →

National Water Commission warns of stressed groundwater systems

Cover page of NWC water stress report
A new report by the National Water Commission defines the concept of ‘water stress’ in groundwater or surface water system.  It describes a nationally consistent method for measuring water stress, as an indicator of potentially overused surface water and groundwater system.  Catchments and aquifers with high levels of stress are identified, and the report discusses whether these systems have water management mechanisms in place to potentially reduce the stress.

The report shows that “despite public focus on the Murray-Darling Basin, the causes of water stress are not confined to the impacts of irrigated agriculture.” Continue Reading →

Groundwater Issues Associated with Coal Seam Gas Development

A forum exploring groundwater issues associated with CSG development and ways that they can be managed.

Tuesday 21 August 2012

5.30pm meet and greet for 6pm start (refreshments provided)

Fritz Loewe Theatre, University of Melbourne, cnr Swanston and Elgin St, Carlton

Coal Seam Gas developments involve the drilling and installation of numerous wells and extraction of large volumes of groundwater.  Please join us as we discuss various issues and risks to groundwater posed by CSG development and the preferred regulatory framework for management.

Sustainability of groundwater usage in northern China – insights from hydrogeochemistry

Northern China is one of the most densely populated and agriculturally productive regions of the world, but also one of its driest and most water-stressed. The productivity of this region and the livelihoods of its people over recent decades have been critically dependent upon high rates of groundwater extraction from a range of major aquifer systems, which provide water for irrigation, industry and domestic consumption. Geochemical tools such as stable and radiogenic isotope tracers offer important insights into the sustainability of groundwater usage from both quantity and quality viewpoints. Continue Reading →

IAH Australia newsletter: Q4 2011 to Q1 2012

The latest edition of the IAH Australia newsletter is now available for download… somewhat late! We’ve been ironing out a couple issues with the new website, and have just increased the file size upload limit so we could post the newsletter. The content may be a little out of date as a result, but we’re getting back on track for the forthcoming newsletters.

The event is a highlight on the WA event calendar and represents a fantastic networking opportunity for members and industry counterparts alike. Continue Reading →

Groundwater catchment characterisation; Bundaberg integrated hydrogeology/ hydrogeophysics investigation

The Australian Society of Exploration Geophysics together with the IAH invite all members to attend a presentation of the findings from a catchment characterisation investigation into the Bundaberg Irrigation Area. More specifically, Geoff Pettifer will discuss how well can we characterise an alluvial / lacustrine / coastal aeolian groundwater system by a fully integrated hydrogeology and geophysics effort.

Geostatistics and water table mapping/time series analysis

This presentation will detail two new statistical tools for shallow hydrogeology, both of which will soon be freely available. The first tool is for time-series modelling of unconfined groundwater hydrographs. It allows the decomposition of a hydrograph to individual drivers, such as pumping and climate, under non-stationary climate conditions while also providing insights into observed trends. General aspects of time-series modelling will be presented, followed by results from the application of the toolto the Great Western paired catchment. The second tool is for probabilistic water table mapping. Continue Reading →
