AWRA Lake Eyre Basin Assessment 2010

This assessment and related data examines water resources in the Lake Eyre Basin region in 2009–10 and over recent decades. Seasonal variability and trends in modelled water flows, stores and levels are considered at the regional level. Details for selected rivers, wetlands, groundwater, urban areas and agriculture are not addressed. At the time of writing, suitable quality controlled and assured information was not identified in the Australian Water Resources Information System (Bureau of Meteorology 2011a). It begins with an overview of key data and information on water flows in the region in recent times followed by a description of the region.
 Key data and information
The assessment presents the 2009–10 annual landscape water flows in the Lake Eyre Basin region (no information is available for major storages in the region). The region experienced very much higher than average rainfall in 2009–10 and this high level of water availability also resulted in very much above average levels of evapotranspiration and landscape water yield1.

本评估及相关数据针对2009-2010年及近数十年的艾尔湖盆地（Lake Eyre Basin）区域水资源状况展开研究。本次研究从区域尺度出发，分析了模拟水流、储水量及水位的季节变异性与变化趋势。本研究未针对选定的河流、湿地、地下水、城市区域及农业领域的细节展开阐述。在本报告撰写之时，澳大利亚水资源信息系统（Australian Water Resources Information System，澳大利亚气象局，2011a）中未获取到经过质量控制且可信度有保障的相关数据。本评估首先概述近期该区域水流相关的核心数据与信息，随后对该区域进行介绍。
核心数据与信息
本评估展示了艾尔湖盆地区域2009-2010年年度地表水流情况（该区域主要蓄水设施暂无相关数据）。该区域在2009-2010年的降雨量远高于平均水平，而充足的水资源供给同时使得蒸散发量与地表产水量¹均远高于平均水平。
