Membership fees for 2016

Membership in the International Association of Hydrogeologists runs by the calendar year (January to December).

IAH Australia will be opening the online portal for 2016 registrations in early January. Another notice will be sent out in January once the portal is up and running.

After much deliberation, the National Committee has voted to freeze registration fees for the 2016 year. As the obligatory remittance to the central IAH office in the UK is the major expenditure for IAH Australia, the National Committee will continue to monitor fluctuations in the Australian dollar exchange rate. Should any changes to the membership fees be required for the 2017 membership year, members will be notified ahead of the next annual general meeting.


2015 IAH Membership Renewal Now open!

IAH Australia wishes to advise that membership registration for the 2015 calendar year is now open.

IAH is pleased to announce that we have in place a new automated membership registration system. We would like to thank members for their patience during the development process. The new system will accept all major credit cards and generate a tax invoice/receipt on payment. Please note renewals through EFT and cheques are not encouraged now that we have the new membership system in place.

IAH Membership is your chance to support us and to receive a great range of benefits, including the Hydrogeology Journal, book and meeting discounts and more. You will also be able to participate in groups, events and schemes, sharing knowledge and experience with others.

IAH memberships run from January 1 to December 31. All memberships will be back-dated to January 1 to ensure you receive the full benefits of your IAH membership.

Membership Fees

We are pleased to announce that the IAH National Committee has unanimously voted to lower student membership fees, effective immediately. And, despite recent increases in fees by IAH International, IAH Australia has frozen all membership fees for the 2015 membership year.

We have a variety of membership types for individuals and companies/organisations, and run a sponsorship scheme for those unable to join the association for financial or practical reasons.

Corporate Membership Renewals

If you are renewing or signing up for Corporate membership or have recently been affiliated with a corporate membership please contact us via the membership email to renew.

IAH VIC – 2013 Darcy Lecture: Managing Groundwater Beneath the Agricultural Landscape

Agricultural land use represents the largest nonpoint source threat to groundwater quality on a global scale. As a result of decades of fertilizer application and surface spreading of animal manure, chronic increases in nutrient concentrations have been documented in both private and municipal well systems. The occurrence of pathogenic microbes in groundwater supply wells has also been associated with agricultural practices at the land surface. Beneficial management practices (BMPs) designed to reduce the risk of groundwater quality impacts in agricultural environments are being implemented worldwide, yet very little data are available to assess the performance of these BMPs.

The complexities associated with variable mass loading to the water table will be explored, considering regional recharge distributions. The role of the vadose zone in controlling subsurface redistribution, and as an archive of past land-use activities, will also be considered relative to the legacy of agricultural impacts on groundwater quality. The performance of a regional-scale BMP program designed to reduce nutrient loading to the subsurface in the vicinity of an impacted municipal groundwater supply system will be evaluated based on more than a decade of field monitoring evidence. The utility of a targeted in situ denitrification approach designed as a remedial strategy to temporarily augment the BMP program in the vicinity of the municipal wells will be addressed based on the results of field experiments.

Finally, the potential influence of extreme climatic variability on the mobility of nutrients and microbial species in agricultural environments will be explored relative to aquifer and well vulnerability.

About the speaker

David L. Rudolph, Ph.D.,PE, a geological engineer, is the 2013 Darcy Lecturer. He is a professor in the Department of Earth and Environmental Sciences and cross-appointed to the Department of Civil and Environmental Engineering at the University of Waterloo. He specializes and teaches in the areas of regional hydrogeology and groundwater protection and management.

The use and abuse of the precautionary principle

The NSW Protection of the Environment Administration Act (PEAA) 1991, provides the following definition of the Precautionary Principle (PP): “If there are threats of serious or irreversible environmental damage, lack of full scientific certainty should not be used as a reasoning for postponing measures to prevent environmental degradation.”

The PP is routinely applied in Groundwater Management. In this context, implementation of the PP typically involves a conservative approach to large-scale management of the resource in which sustainable diversion limits (SDLs) are more likely to be underestimated than overestimated.  For example, in the Murray Darling Basin (MDB), extraction limits for confined aquifers have been based on output from models which simulate the impacts of future groundwater extraction and which have uncertainty associated with them. The sustainable extraction rate derived from the model is scaled down based on model uncertainty to provide an extraction limit that incorporates a “factor of safety”.

On a more local scale, the PP is often applied in decisions about individual groundwater licence applications to account for uncertainty in characterisation of the local hydrogeology. However, there is always some uncertainty. Thus, the decision as to whether the PP should be applied for any particular licence application is somewhat subjective.

It is important not only to manage groundwater resources both regionally and locally in a sustainable manner but in a manner that also ensures they are not unnecessarily locked up. This is recognised in the recently published Sustainable Water Strategies (SWS) in Victoria.

The NSW (PEAA) 1991 also states “In the application of the principle… decisions should be guided by: (i) careful evaluation to avoid, wherever practicable, serious or irreversible damage to the environment; and (ii) an assessment of risk-weighted consequence of various options”.

Rather than routinely applying the PP to conservatively estimate sustainable extraction limits on a whole-aquifer scale or to account for uncertainty in local licence applications, it is important to assess the consequences/risks of both underallocation and overallocation and to facilitate adaptability in management of the resource. In the MDB example above, the consequences would be quite different.
