Groundwater discharge is associated with salinity and pollution problems. The widespread presence of millions of saline lakes in North America, Africa and Australia, shows that across the geological record, most salinity and desertification problems have been caused by saline groundwater discharge. In recent times, dryland salinity has spread widely in southern Australia, resulting in the loss of more than 50% of the fresh streams in Western Australia and causing major salinity problems in the Murray River in South Australia.

Surface And Groundwater

Clearing of agricultural land has resulted in significant changes to the surface and groundwater hydrology. Currently about 10% of agricultural land in Western Australia is affected by dryland salinity and between a quarter and a third of the area is predicted to be lost to salinity before a new hydrological equilibrium is reached. This paper develops a general statement describing the changes to the surface and groundwater hydrology of the wheatbelt of Western Australia between preclearing, the year 2000 and into the future. For typical catchments in the wheatbelt it is estimated that average groundwater recharge and surface runoff have increased about tenfold when comparing the current hydrology to that preclearing. Saline groundwater discharge and flood volumes have also increased significantly. Saline groundwater discharge and associated salt load will probably double in the future in line with the predicted increase in the area of dryland salinity. In addition, future increases in the area of dryland salinity/permanent waterlogging will probably double the volumes in flood events and further increase surface runoff in average years. The outcomes of surface and groundwater management trials have been briefly described to estimate how the hydrology would be modified if the trials were implemented at a catchment scale. These results have been used to formulate possible integrated revegetation and drainage management strategies. The future hydrology and impacts with and without integrated management strategies have been compared.

Abstract A description is provided for Geoglossum cookeanum. Some information on its associated organisms and substrata, habitats, dispersal and transmission and conservation status is given, along with details of its geographical distribution (North America (Mexico and USA (Kentucky, Michigan, New Hampshire and Tenesse)), Asia (Georgia, India (Uttarakhand) and China (Guizhou, Heilongjiang, Jilin and Yunnan)), Australasia (Australia (South Australia, Tasmania, Victoria and Western Australia) and New Zealand), Europe (Austria, Belgium, Czech Republic, Denmark, Estonia, Finland, France, Germany, Ireland, Italy, Luxembourg, Netherlands, Norway, Poland, Russia, Slovakia, Spain, Sweden, Switzerland and UK)). No reports of negative economic impacts of this fungus have been found.

History Of

Christian missionaries played an important role in the Australian nation building that started in the nineteenth century. This essay explores the multifaceted and complex cultural encounters in the context of two aboriginal missions in Australia in the nineteenth century. More specifically, the essay explores the New Norcia mission in Western Australia in 1846-1900 and the Lutheran mission in South Australia in 1838-1853. The essay begins with an overview of the history of the two missions followed by a discussion of the key faces of the cultural encounters that occurred in the course of the missions. This is followed by theological reflections on the encounters in dialogue with contemporary theology, particularly the works of Robert Schreiter.

Balance Analysis

<p>Area studi terletak di bagian tenggara Dataran Tinggi Blackwood, Australia Barat mencakup 71 km<sup>2</sup>. Akifer Yarragadee di daerah studi utamanya tersusun oleh batu pasir yang mengandung lapisan-lapisan batu lempung dan liat. Akifer ini merupakan akifer tak-tertekan karena muncul dipermukaan sepanjang alur Sungai Blackwood pada daerah hilir di Nannup dan merupakan sumber airtanah yang keluar ke sungai. Sungai Blackwood mengalir melintasi Dataran Tinggi Blackwood. Selama musim kering, aliran permukaan ke dalam Sungai Blackwood dapat diabaikan, namun aliran dasar dari airtanah menjadi sumber utama bagi aliran sungai. Neraca air pada daerah studi dilakukan dengan menggunakan analisa jaring-aliran dan kesetimbangan air guna mengevaluasi masukan airtanah dari akifer Yarragadee ke dalam Sungai Blackwood. Mayoritas sel-sel jaring-aliran adalah sel-sel keluaran dan kebanyakan aliran airtanah masuk ke dalam Sungai Blackwood di daerah studi. Curah hujan rata-rata tahunan area studi sekitar 6.7 x 10<sup>7</sup> m<sup>3</sup> a<sup>-1</sup>. Sekitar 9 % dari total curah hujan rata-rata tahunan ini masuk ke dalam tanah sebagai sumber bagi air tanah dan 91 % hilang melalui proses evapotranspirasi. Volume total airtanah yang masuk ke dalam Sungai Blackwood antara stasiun Darradup dan Layman Flat yang dihitung menggunakan analisis jarring-aliran dan kesetimbangan air sekitar 8.1 GL a<sup>-1</sup>.  </p>

In A Fix: Fixed-Term Parliaments in the Australian States

Constitutional systems of Westminster heritage are increasingly moving towards fixed-term parliaments to, amongst other things, prevent the Premier or Prime Minister opportunistically calling a ‘snap election’. Amongst the Australian states, qualified fixed-term parliaments currently exist in New South Wales, South Australia and Victoria. Queensland, Tasmania and Western Australia have also deliberated over whether to establish similar fixed-term parliaments. However, manner and form provisions in those states' constitutions entrench the Parliament's duration, Governor's Office and dissolution power. In Western Australia and Queensland, unlike Tasmania, such provisions are doubly entrenched. This article considers whether these entrenching provisions present legal obstacles to constitutional amendments establishing fixed-term parliaments in those two states. This involves examining whether laws fixing parliamentary terms fall within section 6 of the Australia Acts 1986 (Cth) & (UK). The article concludes by examining recent amendments to the Electoral Act 1907 (WA) designed to enable fixed election dates in Western Australia without requiring a successful referendum.
