Abstract:
Buried paleochannels are of significant interest for understanding hydrological mechanisms and their potential as alluvial gold deposits. Seismic tomographic methods are a suitable solution for resolving the vertical and horizontal structure of such features. We assess a method for seismic 3‐D tomographic inversion from refraction arrivals with reflection control over a suspected paleochannel adjacent to the Wyalong gold fields in the Lachlan fold belt of central New South Wales, Australia. A standard multichannel engineering seismic recording and cable–receiver system was used on a 3‐D field geometry of multiple linear arrays. More than 3000 P‐wave first‐arrival traveltime values were inverted using a regularized inversion scheme for which simplified 2‐D models served as initial velocity–depth models for the complete 3‐D inversion. Seismic reflection arrivals provided additional depth estimates to the bedrock and compensated for a lack of refraction phases at that depth. Correlating the 3‐D seismic velocity–depth data with existing drillhole and nonseismic geophysical data resulted in a detailed structural and compositional interpretation of the paleochannel and the incised regolith. The model suggests the presence of a system of deposits from meandering channels overlying a metasedimentary bedrock formation. The general paleodrainage deposit is relatively conductive in electromagnetic surveys, indicating a potential saline storage or transport mechanism.

Abstract:
Laboratory measurements are described on Permian coals from Wollongong, New South Wales, Australia related to the dependence of ultrasonic P‐ and S‐wave velocities, attenuation, anisotropy and the dynamic elastic moduli on confining pressure, water saturation, and pore pressure. Five independent stiffness constants are used to represent the elastic anisotropy of the specimens as a function of confining pressure and water saturation. The anisotropy is believed to be controlled mainly by the internal structure of the coals, while the pressure dependence of the constants is controlled mainly by randomly oriented cracks. P‐ and S‐wave dispersions were measured on water‐saturated specimens as confining pressures increased from 2 MPa to 40 MPa. The samples represented cores taken both parallel and perpendicular to bedding planes. Velocities along bedding planes are marginally higher than those across bedding planes. This anisotropy is insensitive to confining pressure. Attenuation was also measured, both normal and parallel to bedding planes, on dry and water‐saturated specimens from 2 MPa to 40 MPa confining pressures. The experimental results show that dynamic elastic properties are potential indicators of the states of stress and saturation in coal seams, and provide necessary information for computer modeling and interpreting seismic surveys carried out to assist mine development.

Abstract:
In coastal-estuarine agricultural landscapes that are inherently rich in sulfidic sediments and saline water-tables, natural resource management data need to be collected to describe the heterogeneous nature of the soil, underlying regolith, and interactions with groundwater. Geophysical methods, such as electromagnetic (EM) induction instruments, are increasingly being used. This is because they measure apparent soil electrical conductivity [Formula: see text], which has previously been successfully used to map the areal distribution of soil (e.g., salinity) and hydrological (e.g., water-table depth) properties. We explored the potential of a next-generation DUALEM-421 and EM34 to be used independently and in conjunction with each other to provide information we can use to represent the pedological and hydrogeological setting of alluvial and estuarine sediments. A 1D laterally constrained joint-inversion algorithm can account for the nonlinearity of large [Formula: see text] (i.e., [Formula: see text]). We applied this algorithm to develop 2D cross sections of electrical conductivity ([Formula: see text]) from DUALEM-421 and EM34 [Formula: see text] data acquired across an estuarine landscape and situated within Quaternary fluvial sediments adjacent to Rocky Mouth Creek on the far north coast of New South Wales, Australia. We compared this joint-inversion model with inversions of the DUALEM-421 and EM34 [Formula: see text] data independently of each other. For the most part, the general patterns of the inverted models of [Formula: see text] compare favorably with existing pedological and hydrogeological interpretations, based on results achieved during a previous geoelectrical survey. However, the joint-inversion provides a more realistic model of the location and extent of a saline water-table and associated with the location of sulfidic sediments.

Abstract:
Two large-scale, long-term biodiversity monitoring programs examining vertebrate responses to habitat fragmentation and landscape change in agricultural landscapes are taking place in the Murray Catchment Management Area of New South Wales, south-eastern Australia. Field surveys involve counting reptiles under a range of management conditions and across a broad range of vegetation types in two bioregions, the South-western Slopes of New South Wales and the Riverina. We list reptiles recorded during surveys conducted between 2002 and 2009. We include additional species recorded between 1997 and 2009 from a conservation reserve. Thirty-nine species from nine families were recorded. The list will be useful for workers interested in reptile zoogeographical distributions and habitat associations as well as those interested in the biodiversity value of remnant vegetation and tree plantings in fragmented agricultural landscapes.

Abstract:
A large-scale, long-term study of the impacts on vertebrates of landscape change and habitat fragmentation is taking place at Tumut in southern New South Wales, south-eastern Australia. Field surveys focus on counting birds within three broad kinds of sites in the study region. These are: (1) A randomized and replicated set of 85 sites in remnants or fragments of native Eucalyptus forest located within the boundaries of the Radiata Pine plantation. (2) Sites dominated by Radiata Pine plantation trees (N = 40 sites). (3) Sites in the large areas of continuous Eucalyptus forest adjacent to the plantation that act as “controls” (N = 40 sites). We list of birds recorded during 1996 and 1997. A total of 92 species from 34 families was recorded. The list will be useful for workers examining bird responses to fragmented landscapes as well as those interested in the biodiversity values of plantation landscapes.

Abstract:
Dryland salinity occurs extensively throughout the Spicers Creek Catchment in central west New South Wales, Australia. The extent of dryland salinity in the Spicers Creek Catchment has severely altered the landscape, having major environmental implication. Large area of the catchments has experienced soil erosion resulting from the saline groundwater in the surface soil causing the destruction of clay and soil structure. The objective of this study was to use seismic refraction methods to map in detail a shear zone, which was associated with an area of major dryland salination. In particular, both the width of shear zone and the rock fabric within it were to be mapped with two both compressional (P) and shear (S) waves using a three-dimensional (3D) array of three- component (3C) receivers. The seismic data was recorded across a shear zone which is associated with salination in the Spicers Creek Catchment using the Australian National Seismic Imaging Resources (ANSIR) 360-trace system. Three-component (3C) geophones were used to record shear waves as well as compressional wave. An IVI minivibrator T-15000 was used as the main source of energy for the seismic survey. The results of the three-dimensional three-component seismic refraction surveys at the Spicers Creek Catchment show that the shear zone exhibit the seismic geophysical anomaly of a shear zone, existing as a narrow region with low seismic velocities and increased depth of weathering. A detailed analysis of the refractor seismic velocities and amplitude show a number of linear features parallel to and cross-cutting the shear zone. Linear features cut the shear zones at each site. They have been interpreted as a series of recent faults which act as discharge zone bringing saline groundwater to the surface.

Abstract:
AbstractThis paper presents and discusses the mechanisms of rainfall-induced shallow landslides that commonly occur in South East Queensland (SEQ) and northern New South Wales (NSW), Australia. The major factors causing the formation of landslide mass such as geology, weathering, and rainfall patterns were discussed. Results from field surveys and laboratory testing of rock/soil material from landslide masses were presented, and relationships between the material strength and landslide occurrence were drawn. It was found that most of shallow slides were related to sandstone deposits. Those failures occurred on natural slopes and road cuts with the inclination of the failure plane being in the range of 35–45°. For natural slopes where the landslide mass mostly consisted of coarse-grained soil, the relationship between the soil strength and water content was established. In addition, the relationship between rainfall patterns such as intensity and duration, and the landslide occurrence was presented. Based on the data from field work and laboratory results including a series of flume tests, the mechanism of shallow landslides triggered by rainfall events was identified and discussed.

Abstract:
The Australian Fire Danger Rating System (AFDRS) was launched on 1 September 2022, bringing a generational change to the way that Australia calculates and communicates fire danger. Its focus is improved public safety and reduced impacts of bushfires though: • Improving the science behind fire danger predictions. • Improving the way that fire danger is communicated. • Providing government and industry with better decision-making tools. • Reducing future costs associated with bushfire impacts. The previous fire danger rating system was introduced in the 1960’s by Australia’s first full-time bushfire researcher, Alan McArthur, based on extensive experimental fires. While useful, the system included only two fire behaviour models (dry sclerophyll forest and grassland), was not easily updateable and fires were being experienced that increasingly exceeded its design parameters. In July 2014, Senior Officers and Ministers agreed that the development of a new system was a national priority. The new system was developed by the New South Wales Rural Fire Service in collaboration with the Bureau of Meteorology, all Australian states and territories and the Commonwealth government. Program management and system implementation were coordinated by AFAC (Australia’s National Council for Fire and Emergency Services). The new AFDRS uses contemporary fire behaviour science, makes better use of available data and uses software infrastructure that can be continuously improved. The AFDRS starts with eight fire behaviour models representing a representative range of Australian vegetation types, it captures current fuel information, uses satellite data, integrates weather from the Bureau of Meteorology and calculates fire danger down to a 1.5km by 1.5-kilometer grid. These calculations are linked to tools that assist fire operational decision-making via a Fire Behaviour Index that is calibrated to operational implications for fire management. A separate arm of the project developed a public-facing Fire Danger Rating framework, guided by one of Australia’s largest social research projects. The research found that, while fire danger signage was well recognised, few acted on fire danger ratings to plan their activities. Focus groups and subsequent surveys found that the community preferred a simplified public-facing system where each fire danger rating had a distinct call to action. The implementation of the new system required an enormous effort from all levels of government across all States and Territories as well as the Commonwealth. It required updates to legislation, policy, procedures, web pages and other IT infrastructure, as well as replacement of physical signage. However, as a result, Australia has a significantly new way of calculating and communicating fire danger, that is continuously improvable and which will bring benefits for decades to come.
