    Description: Diese Arbeit beschäftigt sich mit der Verknüpfung von manuellen und automatischen Inversionmethoden für die Interpretation gravimetrischer Anomalien. Eine neue Software mit dem Namen 3GRAINS wird vorgestellt. Sie wurde für das manuelle Modellieren entwickelt und benutzt rechteckförmige Prismen zur Berechnung des gravimetrischen Effekts eines Modells. Die Software bietet eine graphische Benutzeroberfläche, um eine komfortable Arbeit mit einer modellierten Struktur zu ermöglichen. Ein automatischer Inversionsalgorithmus basiert auf der Idee der evolutionären Berechnung. Die dargestellten Methoden werden auf die Interpretation der gravimetrischen Anomalien der Hellenischen Subduktionszone angewendet. Die tektonische Situation dieser Region und seismische Beobachtungen werden vorgestellt. Der Prozess der Datengewinnung und der Datenbearbeitung wird beschrieben. Schließlich werden die Ergebnisse der Interpretation der gravimetrischen Anomalien präsentiert.

    Description: The Resource Assessment Branch of the Department of Water Land and Biodiversity Conservation (DWLBC) is currently undertaking the ‘Northern Adelaide Plains Prescribed Wells Area Well Investigation Project’ for the Northern Adelaide and Barossa Catchment Water Management Board (NABCWMB). This report provides an overview of the issues, results to date and future directions for the project. Stage 1 of the Leaky Wells Project is designed to audit and compile an accurate list of licensed irrigation wells within the Northern Adelaide Plains (NAP) Prescribed Wells Area (PWA). Of these licensed wells pumped salinity samples were to be collected by the licence holder and submitted for analysis. From a review of these wells and recorded salinity information all wells determined to be contaminating the major production aquifers were to be identified, investigated and remedial action undertaken. Stage 2 of the Leaky Wells Project aimed to assess the condition of the 2868 abandoned and disused wells throughout the NAP. As mentioned in the Administrative Agreement, it was expected that this phase of the project would be the most intensive, requiring considerable field investigations to determine the locations and current condition of these wells.

    Description: Paläoseismologische Daten lassen vermuten, dass viele aktive Störungen in unterschiedlichen tektonischen Settings eine Veränderung in der Bewegungsrate auf der Störung kurz nach dem Ende des letzten glazialen Maximums erfahren haben. Als Beispiel seien die postglazial entstandenen oder reaktivierten Pärve Überschiebung oder die Stuoragurra Überschiebung in Nord Skandinavien (Lappland Fault Province), aber auch die über Millionen Jahre aktive Wasatch Abschiebung in der Basin and Range Province oder die Tote Mehr Transform Störung genannt. In dieser Arbeit werden dreidimensionale Finite Elemente Modelle benutzt um den Einfluss von Lastwechseln auf der Erdoberfläche auf das Verhalten einzelner Störungen zu untersuchen. Die Resultate dieser Arbeit zeigen, dass klimabedingte Volumenänderungen von Gletschern und Seen auf der Erdoberfläche das Spannungsfeld der Kruste beeinflussen. Generell gilt: Lastzunahme führt zu verringerten, Entlastung zu erhöhten Bewegungsraten auf der Störung.

    Description: Anhand des Modellfalls der Sesia Zone in den West-Alpen werden mikrostrukturelle Kriterien für syn- und postseismische Deformation in der oberen Plastosphäre in Folge eines großen Erdbebens in der überlagernden Schizosphäre ausgearbeitet. Die Orientierungsverteilung von mechanisch verzwillingten Jadeiten liefert Hinweise auf Spitzten-Spannungen 〉0,5 GPa. Die Vielfalt unterschiedlicher Quarz-Mikrostrukturen spiegelt progressive Deformation bei relaxierenden Spannungen in einem Temperaturbereich von 300-350 ʿC wider. Ein dazu konsistentes Bild liefert die kataklastische Deformation von Granat. Verheilte Mikrorisse in Quarz, verfüllte Risse in Granat sowie mesoskopische, diskordante Quarz-Gänge mit rekristallisierter Füllung geben Hinweise auf einen fluktuierenden Porenfluiddruck. Dieses Beispiel aus der Sesia Zone veranschaulicht die Bedeutung nicht-stationärer Deformation in der oberen Plastosphäre, entgegen konventionellen Vorstellungen von dominierend stationärem Fließen.

    Description: The Barossa Basin is a complex hydrogeological environment containing a sedimentary aquifer system surrounded and underlain by a dual porosity fractured rock aquifer. The hydraulic relationship between the fractured rock aquifer and the sedimentary aquifers is poorly understood. The difficulties in describing the movement of groundwater through dual porosity media such as a fractured rock aquifer are well documented. While groundwater flow in the sedimentary aquifers can be adequately described using porous media flow techniques in the Barossa Basin, our understanding of interconnectivity between individual sedimentary aquifers is again poor. The Basin itself is narrow and, immediately adjacent to the Stockwell Fault on the eastern side of the valley, relatively deep (~200 m). Sediments deposited into the trough consisted of mainly discontinuous sequences of overlapping sands and carbonaceous clays. This was followed by the deposition of gravels, sands and clays that form the Barossa Valley as it is today. Various authors have sub-divided the geology into individual hydrostratigraphical units. However, a review of the literature highlighted inconsistencies in the number of aquifers recognised, their exact spatial distribution within the Basin, and that there have been changes in nomenclature that are not satisfactorily described. This has resulted in some confusion that requires clarification ...

    Description: Aquifer Storage and Recovery (ASR) has the potential to utilise surface water resources, including urban stormwater runoff and treated wastewater that is largely wasted; thereby relieving the pressure on groundwater resources. In the broader sense, opportunities exist to use ASR to rethink our traditional water management and distribution policies, and to provide cost-effective and innovative alternatives to current methods of water supply. In South Australia, an increasing amount of stress is being placed on surface and groundwater resources to meet demands from expanding irrigated horticultural areas and urban populations. ASR can be used to reduce some of the pressure on traditional supplies of water, especially in metropolitan areas. But the sources of water for ASR must be carefully considered especially in rural areas so as not to shift the burden from one water supply source to another. A number of issues surround the use of ASR as a water management solution and these relate principally to water quality and water quantity. In rural areas, for example, the 'harvesting' of water from creeks and streams may result in extra pressure on an already stressed resource by further reducing the amount of water available to the environment. In urban areas the expanse of paved surfaces provides an ideal medium to capture large volumes of stormwater runoff. However, the volumes are often well in excess of any potential local demand. Understanding ASR technology ensures success in almost all situations ...

    Description: Groundwater is Eyre Peninsula's most precious resource and has become the sole source of reticulated water to meet potable and industrial demand. Water resources on Eyre Peninsula are scarce and fragile, particularly in the low rainfall regions, with few reliable freshwater streams and the groundwater availability is highly variable. The groundwater recharge and hence the security of the resource, is highly dependent upon local rainfall, landcover and landuse. Surface water is scarce and unreliable, and reticulated water is limited. Difficulty in accessing water resources has placed both a social and economic burden on the rural community throughout the region. The information contained on the CD will provide a vital framework for the future management planning of the available resources in the region.

    Description: Lincoln on Eyre Peninsula. It covers an area of ~70 km2 and comprises all or parts of the Hundreds of Lincoln, Wanilla, Lake Wangary, Uley, Sleaford and Flinders. The boundaries of the area are presented on Figure 1. In general water resources are limited in occurrence throughout the Eyre Peninsula. In the Southern Basins there is very little available surface water with one permanent and two ephemeral saline lakes, and two brackish lakes that feed ephemeral watercourses. However, there are moderately good supplies of groundwater resources, which provide a large part of the reticulated water supply for the Eyre Peninsula. The area is generally characterised by undulating topographic relief typical of an ancient dunal system with dramatic coastal cliffs and large internal drainage catchments. Ground level elevations range from 140 m coastal cliffs to inland depressions reaching near sea level to bedrock highs exceeding 200 m. The area incorporates the Kellidie Bay and Sleaford Mere Conservation Parks and parts of the Lincoln and Coffin Bay National Parks, which are managed under the National Parks and Wildlife Act 1972. Pursuant to this Act, park management plans have been prepared for the Lincoln and Coffin Bay National Parks and Kellidie Bay Conservation Park ...

    Description: The Saunders Creek is a tributary catchment for the River Murray which generates ephemeral flows in very wet years. Concerns have been expressed at the construction of large dams in the headwaters of the catchment, and their impacts on streamflow, and consequently recharge to aquifers. The catchment can be divided into two distinct groundwater regions: the Hills Zone and the Plains Zone. The Hills Zone comprises the consolidated basement rocks of the Mount Lofty Ranges, which form fractured rock aquifers. Borehole yields are generally low and salinities vary, apart from the western portion of the catchment where better quality water is drawn. The Plains Zone is underlain by unconsolidated sediments of the Murray Basin. The main aquifer is the Murray Group Limestone, which is utilised for domestic and stock purposes and is recharged mainly by infiltration of streamflow.

    Description: The Noora Prescribed Wells Area (PWA) lies over the deepest part of the Murray Basin in the far eastern boundary of South Australia (Fig. 1). It is bordered to the north by the River Murray, to the east by the South Australia Victoria border, to the south by the southern border of the Hundred of Bookpurnong and the west by a line parallel to and 20 km west from the South Australia Victoria border. Two aquifers are monitored in the Noora PWA: the Pliocene Sands Aquifer (topmost and unconfined) and the confined Murray Group Limestone Aquifer. Both aquifers contain mostly poor quality water with current limited use only for stock, but with potential uses for mining and industry. Groundwater flows in a westerly direction in each aquifer towards the River Murray. A third aquifer underlies the Murray Group Limestone Aquifer: the Renmark Group Aquifer. No current water level data is available for this aquifer system in the Noora PWA and it was therefore omitted from this monitoring report. There have been three main impacts of human settlement on the Noora PWA: land clearance, irrigation and the construction of the Noora Disposal Basin. All three have altered the hydrogeological balance in the Noora PWA by causing a rise in the watertable.
