Abstract

ABSTRACT Lakes Frome, Callabonna, Blanche and Gregory are playa lakes on the eastern and northern sides of the Flinders Ranges, South Australia. Between 2007 and 2019 we surveyed key topographic features of the lakes, including shorelines, lake floors and the alluvial sills that separate the lakes with differential GPS (DGPS). We combine these observations with the analysis of a hybrid DEM that blends data from multiple sources. The lowest elevation of the Frome-Callabonna system based on the hybrid DEM is −8.33 m Australian Height Datum (AHD) at Lake Callabonna but −5.42 m AHD based on DGPS field data. Both values are considerably lower than previous estimates based on spot heights and contours. The DGPS data for Lake Callabonna support the Shuttle Radar Terrestrial Mission (SRTM) estimates of lake-floor elevations but with a mean difference of 1.7 m in elevation. There are larger differences in elevation between the hybrid DEM and the DGPS data for the floor of Lake Frome (mean difference of 4.25 m). We also report on a newly topographically surveyed high shoreline at Lake Callabonna between 20.1 and 20.8 m AHD, the highest to date.

Frome-Callabonna系统的地形洞察和新测量的高地海岸线的海拔
Frome湖、Callabonna湖、Blanche湖和Gregory湖是位于南澳大利亚弗林德斯山脉东侧和北侧的playa湖。在2007年至2019年期间,我们用差分GPS (DGPS)调查了湖泊的主要地形特征,包括海岸线、湖底和将湖泊分开的冲积层。我们将这些观测结果与混合了多个来源数据的混合DEM分析相结合。基于混合DEM的from -Callabonna系统在Callabonna湖的最低海拔为- 8.33 m Australian Height Datum (AHD),而基于DGPS野外数据的最低海拔为- 5.42 m。这两个值都比以前根据斑点高度和等高线估计的值低得多。卡拉博纳湖的DGPS数据支持航天飞机雷达地面任务(SRTM)对湖底海拔的估计,但平均海拔差为1.7米。在混合DEM和DGPS数据之间,Frome湖底的高程差异较大(平均差异为4.25 m)。我们还报道了Callabonna湖新地形调查的高岸线在海拔20.1 - 20.8 m之间,这是迄今为止最高的。

期刊介绍: Published since 1880, the Transactions of the Royal Society of South Australia is a multidisciplinary journal that aims to publish high quality, peer-reviewed papers of particular relevance to Australasia. There is a particular focus on natural history topics such as: botany, zoology, geology, geomorphology, palaeontology, meteorology, geophysics, biophysics, soil science and environmental science, and environmental health. However, the journal is not restricted to these fields, with papers concerning epidemiology, ethnology, anthropology, linguistics, and the history of science and exploration also welcomed. Submissions are welcome from all authors, and membership of the Royal Society of South Australia is not required. The following types of manuscripts are welcome: Reviews, Original Research Papers, History of Science and Exploration, Brief Communications, Obituaries.
