Engineers' conference, Hobart, March, 1959; with special reference to hydro-electric works

I attended the Annual Conference of the Institution of Engineers, Australia, at Hobart, from the 16th - 20th March,
and took part in one of the post-sessional excursions to HydroElectric Works and to Bell Bay Aluminium Plant from the 21st - 23rd. Sessions devoted to technical papers were well organised and occupied in all two full days in the week; technical sessions alternated with visits to laboratories and hydro-electric installations etc., which occupied another two days of the conference week.
Technical papers were given in two concurrent sessions dealing with different branches of engineering. In each session
two papers, printed and circulated to members before the conference, occupied a morning or afternoon period; the speaker had threequarters to one hour to explain his paper followed by discussion lasting some forty minutes. In each case, discussion was opened by an appointed discussion leader whose associations or experience made his contribution particularly well worthwhile. This pattern for the presentation of technical papers might well be followed in some of the sessions in science congresses; it provides full development of both paper and discussion; the only valid criticism of the Hobart sessions is that some of the discussion leaders spoke for fifteen minutes or more and thus restricted general  discussion.
Local engineers and engineering organisations, particularly the Hydro-Electric Commission of Tasmania, were most generous and hospitable, but in general the excursions were not well run on the technical side; much more information could have been presented in summary or by local engineers had such been allocated to individual buses.
The value of this conference to the engineering geologist was derived from technical papers, as those on penstocks,
pre-stressed dams and the Great Lake development; from many unofficial discussions with engineers and H.E.C. geologists on foundation problems, seismic hazards, materials for dams and tunnelling costs and problems; and from observations in the field as to how problems have been tackled. Of considerable importance are the new contacts made in the field of engineering from which assistance or opinions may be obtained in future work. The most important of the contacts made in Hobart are listed in Appendix I. All of these men are most approachable and co-operative and would be happy to help in our work.
The following summary of the Conference is restricted to information likely to be of use or interest to the Geological
Section; it has been gleaned from technical papers, unofficial discussion and from observations at hydro-electric installations.

Australian Ordovician pelecypod molluscs

Pelecypod molluscs are widespread and reasonably abundant in the Ordovician rocks of Tasmania and the Amadeus and Georgina Basins of northern Australia. Because the mollusc faunas of these areas are not well known, this study concentrates on their systematics. We deal with 47 species of pelecypods, which are placed in 31 genera; 38 species are named and nine are treated within open nomenclature. Twenty-seven of the named species and 20 of the genera are newly named herein: Ctenodonta youngi sp. nov., C. macalesteri sp. nov., Alococoncha gen. nov., Fidera maryae gen. novo et sp. nov., Deceptrix banksi sp. nov., Eritropis gen. nov., Inaequidens davisi gen. novo et sp. nov., I. campbelli sp. nov., lohnmartinia cordata gen. novo et sp. nov., Lophoconcha gen. nov., Palaeoneilo smithi sp. nov., Sthenodonta jelli gen. novo et sp. nov., S. passmoreae sp. nov., Zeehania jacksoni gen. novo et sp. nov., Cyrtodonta carberryi sp. nov., C. hazeli sp. nov., C. stafJordae sp. nov., Cyrtodontula hadzeli sp. nov., C. sohli sp. nov., Pharcidoconcha raupi gen. novo et sp. nov., Leconychia doylei gen. novo et sp. nov., Glyptonychia wilsoni gen. novo et sp. nov., Pteronychia haupti gen. novo et sp. nov., Denticelox gen. nov., Runnegaria cuneata gen. novo et sp. nov., Colpantyx woolleyi gen. novo et sp. nov., Xestoconcha kraciukae gen. novo et sp. nov., Copidens browni gen. novo et sp. nov., Brachilyrodesma radkei gen. novo et sp. nov., Noradonta shergoldi gen. novo et sp. nov., and Sphenosolen draperi gen. novo et sp. novo The eleven species named by Tate (1896) and Iohnston (1888) are considered, and their generic-level assignments are updated. The species 'Pteronites' micans Tate is based on the genal spine of a trilobite and is not a pinnid pelecypod. A new family Colpomyidae is erected within the superfamily Mytilacea. Twenty-six of the species are at present known only from the Amadeus Basin, nine only from the Georgina Basin, and two (possibly three) are common to both basins. Ten species are known from Tasmania, none of which are in common with mainland Australian spocies. The specimens were collected from 91 localities. The age of the pelecypods ranges from Early Ordovician (Arenigian) to Late Ordovician (Richmondian); most species occur in lower Middle Ordovician rocks. Most of the Tasmanian species are found in limestones, whereas most of those from the mainland are in coarse clastic rocks. In addition to the pelecypods, we comment briefly on six species of rostroconch molluscs, two of which are newly named: Tolmachovia corbetti sp. novo and Bransonia townleyi sp. Novo.

The Creation of High Resolution Bathymetry Grids for Christmas Island

Christmas Island is located approximately 2,600 North West of Perth. It is the surface expression of an emergent seamount uplifted by tectonics. Bathymetry data are required in this area to help identify major seabed processes and habitats. The data are also required to enable modelling of tsunami as they interact with the shelf around the island and the coast. This report describes the methodology employed in creating detailed bathymetry data grids of the Christmas Island region. It covers data collection, quality control and gridding. Descriptions are provided of each dataset employed, the methods used to integrate the different datasets and the attributes of the new bathymetric models. Five new bathymetry grids are presented, including grids that integrate bathymetry with the island's topography.This dataset is not to be used for navigational purposes.

Reliable assessment of flood impact: an urban stormwater case study of a City of Sydney catchment

The flood risk in many urban catchments is poorly understood. Legacy stormwater infrastructure is often substandard and anticipated climate change induced sea level rise and increased rainfall intensity will typically exacerbate present risk. In a Department of Climate Change and Energy Efficiency (DCCEE) funded collaboration between Geoscience Australia (GA) and the City of Sydney (CoS), the impacts on the Alexandra Canal catchment have been studied. This work has built upon detailed flood hazard analyses by Cardno commissioned by the CoS and has entailed the development of exposure and vulnerability information. Significantly, the case study has highlighted the value of robust exposure attributes and vulnerability models in the development of flood risk knowledge.
The paper describes how vulnerability knowledge developed following the 2011 Brisbane floods to include key building types found in the inner suburb of Sydney. It also describes the systematic field capture of building exposure information in the catchment area and its categorisation into 19 generic building types. The assessment of ground floor heights using the Field Data Analysis Tool (FiDAT) developed at Geoscience Australia is also presented.
The selected hazard scenario was a 100 year ARI event with 20% increased rainfall intensity accompanied by a 0.55m sea level rise in Botany Bay. The impact from the selected scenario was assessed in terms of monetary loss for four combinations of vulnerability model suite (GA and NSW Government) and floor height attribution method (assumed 0.15m uniformly and evaluated from LiDAR and street view imagery).
It was observed that the total loss is higher in the case of assumed floor heights compared to FiDAT processed floor heights as the former failed to capture increased floor heights for newer construction. However, the loss is lower when only two vulnerability models developed by NSW Government are applied for the entire building stock in the region as two models could not reliably represent the whole building stock.

Tanami - The Granites Infill (P199908), gravity point data

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
 This Tanami - The Granites Infill (P199908) contains a total of 3870 point data values acquired at a spacing between 1000 and 4000 metres. The data is located in NT and were acquired in 1999, under project No. 199908 for Australian Geological Survey Organisation (AGSO); Northern Territory of Australia (Northern Territory Geological Survey).

Lissadell total count grid geodetic

The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose. The terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to this grid to generate the filtered terrestrial dose rate grid.
This Lissadell total count grid geodetic has a cell size of 0.00083 degrees (approximately 91m) and shows the terrestrial dose rate of the Lissadell, WA, 1994. The data used to produce this grid was acquired in 1994 by the WA Government, and consisted of 50670 line-kilometres of data at 400m line spacing and 100m terrain clearance.

MH370 Phase 1 150m Bathymetry datasets (GA-4421,GA-4422 & GA-4430)

On behalf of Australia, the Australian Transport Safety Bureau (ATSB) is leading search operations for missing Malaysian airlines flight MH370 in the Southern Indian Ocean. Geoscience Australia provided advice, expertise and support to the ATSB to facilitate bathymetric surveys, which were undertaken to provide a detailed map of the sea floor topography to aid navigation during the underwater search. Bathymetric data was acquired by multibeam sonar mounted on the hull of multiple vessels (GA survey reference: GA-4421, GA-4422 &amp; GA-4430). Bathymetric surveys were conducted from June 2014 to February 2017, collecting over 710,000 square kilometres of data in the search area and along transit lines (to and from the search area). This dataset allows exploration of the seafloor topography of bathymetry data at a resolution of 150 m across the search and transit areas of the Southern Indian Ocean. The dataset is overlain on a hillshade created from the 150m resolution bathymetry data. The hillshade was created with the parameters of point illumination azimuth at 45 degrees and altitude of 45 degrees.This dataset is not to be used for navigational purposes.

Towards real-time earthquake impact alerting in Indonesia

The Government of Indonesia has committed to deploying a network of 500 strong-motion sensors throughout the nation. The data from these sensors have the potential to provide critical near-real-time information on the level of ground shaking and potential impact from Indonesian earthquakes near communities. We describe the implementation of real-time ‘ShakeMaps’ within Indonesia's Agency of Meteorology, Climatology and Geophysics (BMKG). These ShakeMaps are intended to underpin real-time earthquake situational awareness tools.
The use of the new strong-motion network is demonstrated for two recent earthquakes in northern Sumatra: the 2 July 2013 Mw 6.1 Bener Meriah, Sumatra and the 10 October 2013 Mw 5.4 Aceh Besar earthquakes. The former earthquake resulted in 35 fatalities, with a further 2400 reported injuries. The recently integrated ShakeMap system automatically generated shaking estimates calibrated by BMKG's strong-motion network within 7 min of the Bener Meriah earthquake's origin, which assisted the emergency response efforts. Recorded ground motions are generally consistent with theoretical models. However, more analysis is required to fully characterize the attenuation of strong ground motion in Indonesia.

A national-scale assessment of carbonatite-related rare earth element mineral system potential in Australia

The production of rare earth elements (REEs) is critical to the global transition to a low carbon economy. Carbonatites represent a significant source of REEs, both domestically within Australia, as well as globally. Given their strategic importance for the Australian economy, a national mineral potential assessment has been undertaken as part of the Exploring for the Future program at Geoscience Australia to evaluate the potential for carbonatite-related REE (CREE) mineral systems. Rather than aiming to identify individual carbonatites and/or CREE deposits, the focus of the mineral potential assessment is to delineate prospective belts or districts within Australia that indicate the presence of favourable criteria, particularly in terms of lithospheric architecture, that may lead to the formation of a CREE mineral system.

This study demonstrates how national-scale multidisciplinary precompetitive geoscience datasets can be integrated using a hybrid methodology that incorporates robust statistical analysis with mineral systems expertise to predictively map areas that have a higher geological potential for the formation of CREE mineral systems and effectively reduce the exploration search space. Statistical evaluation of the relationship between different mappable criteria that represent spatial proxies for mineral system processes and known carbonatites and CREE deposits has been undertaken to test previously published hypotheses on how to target CREE mineral systems at a broad-scale. The results confirm the relevance of most criteria in the Australian context, while several new criteria such as distance to large igneous province margins and distance to magnetic worms have also been shown to have a strong correlation with known carbonatites and CREE deposits. Using a hybrid knowledge- and data-driven mineral potential mapping approach, the mineral potential map predicts the location of known carbonatite and CREE deposits, while also demonstrating additional areas of high prospectivity in regions with no previously identified carbonatites or CREE mineralisation.
Presented at the AusIMM Critical Minerals Conference 2023.
