Sustainable Expansion of Irrigated Agriculture and Horticulture in Northern Adelaide Corridor ED-17-01

充分释放南澳大利亚州资源、能源和可再生资产的潜力已成为南澳大利亚州政府的经济优先事项。政府和机构认为，沿着北阿德莱德走廊扩大园艺种植，有可能为南澳大利亚州实现显著的经济发展。阿德莱德北部走廊(包括阿德莱德平原北部)园艺和农业做法的可持续性和推广受到现有供水的可持续性以及这些水资源和潜在新水资源的水质的强烈影响。<br/> <br/> 该项目(ED.17.01项目)由戈伊德水研究所资助。该项目分为五个不同的任务，具体如下：<br/> <br/> 发展和优化模型域和灌溉扩展对接收环境的影响评估<br/> <br/> 模拟营养和化学命运，包括盐度/碱度风险，以此作为确定当前和未来气候下再生水利用寿命和缓解策略的基础<br/> <br/> 水源选项/水的可用性、质量、处理和存储考虑<br/> <br/> 地下水深度评估(概念验证)和<br/> <br/> 将以前的四项任务合并成一份综合报告，并建议制定指导方针。<br/> <br/> 任务3数据集及其衍生的子模型被集成到名为“覆盖作物灌溉水质和数量模型”(或“IW-QC2”)的Microsoft Excel业务模型中，通过野外样本采集、气候模拟、历史和预测降雨量数据、从政府机构、自来水公司、行业和协会等各种来源获得的可用水质数据，以及通过土地所有者调查获得。任务3的主要目的是更好地了解国家行动方案已有的和潜在的新水资源(包括混合和/或处理)的质量和数量，以及进一步向北延伸到莱特河、园艺实践，并提供其他项目任务所需的数据。对供水选择的考虑是基于季节性供应、各种作物类型的适宜用途水质和实践需要，通过混合现有的和潜在的(包括通过处理过程)新的水资源(例如各种盐碱度的地下水和雨水收集)。开发IW-QC2模型是为了能够根据选定的作物类型、气候预测模型和当前的园艺实践，随时确定和/或预测水资源可获得性、水质和处理需求。该模型在Excel中形成了一个平台，在该平台上可以扩展作物类型，以及包含和应用替代气候预测模型。

Unlocking the full potential of South Australia's resources, energy and renewable assets has become an economic priority for the South Australian Government. Expansion of horticulture along the Northern Adelaide Corridor is viewed by governments and agencies as having potential to achieve significant economic development for the state of South Australia. Sustainability and expansion of horticultural and agricultural practices in the Northern Adelaide Corridor (including the Northern Adelaide Plains, NAP) is strongly influenced by the sustainability of existing water supplies and water qualities of these and potential new water resources. <br /> <br /> This project (Project ED.17.01) was funded through the Goyder Institute for Water Research. The project was structured into five distinct tasks, as follows: <br /> <br /> Development and optimisation of modelling domain and impact assessment of irrigation expansion on the receiving environment <br /> <br /> Modelling nutrient and chemical fate, including salinity/sodicity risk, as the basis for identifying longevity of recycled water utilization and mitigation strategies under current and future climate <br /> <br /> Source water options / water availability, quality, treatment and storage considerations <br /> <br /> Assessment of Depth to Groundwater (Proof of Concept) and <br /> <br /> Integration of the four previous tasks into a consolidated report and suggested guideline development. <br /> <br /> The Task 3 dataset and derived sub-models integrated into a Microsoft Excel operational model called 'Irrigation water quality and quantity for covered crops model' (or 'IW-QC2') were acquired through field sample collections, climate modelling, historic and predicted rainfall data, available water quality data accessed from various sources such as government agencies, water corporation, industry and associations, and through a landholder survey. The key aim of Task 3, was to develop an improved understanding of the qualities and quantities of established and potential new water resources (with blending and/or treatment) for the NAP and further north to the Light River, horticultural practices, and provide data needed for the other project tasks. Consideration of water supply options were based on seasonal availability, fit-for-purpose water quality for various crop types and practice needs, through blending of existing and potential (including through treatment processes) new water resources (such as groundwaters of various salinities and rainwater harvesting). The IW-QC2 model was developed to enable ready determination and or prediction of water resource availability, water quality and treatment needs based on selected crop types, climate prediction modelling and current horticulture practices. The model, in Excel forms a platform on which crop types can be expanded as well as inclusion and application of alternative climate prediction models.
