Modelling the impact on infrastructure resilience of local vegetation-influenced ground movement with multi-scale spatio-temporal environmental data

研究项目的简要定义：英国水网包括不同材料，直径和年龄的管道。这些管道被埋在不同的土壤中，并且有不同的外部因素影响其弹性。我们知道地面移动会破坏管道，但由于环境和管道网络的复杂性，预测爆裂的数量，特别是最有可能发生的地方，仍然非常具有挑战性。根据我们研究区域内2800万棵树的位置、高度和树冠，您将计算“树木影响”土壤湿度的区域，并使用这些区域来预测高度局部的地面运动。预计将新的树数据集纳入基础设施-环境模型将提高我们预测爆裂管道位置的能力。通过对Anglian Water地区长达10年的大型历史性案例研究，这将是基于土壤、天气和树木变量的环境-水基础设施模型第一次在这种规模上得到开发和测试。您将使用一系列统计方法来测试假设的关系，以评估基础设施和环境变量对每个基础设施故障的相对贡献。在未来气候条件下，树木对当地土壤湿度的变化影响也将被模拟。由于英国供水网络的年龄和完整性变化，这项工作将具有国家重要性，因为它将有助于集中有限的可用资源进行维修和更换，这将在减少泄漏和相关能源成本，对附近基础设施的附带损害以及最大限度地减少故障对人类和环境的潜在影响方面带来最大利益。

Brief definition of research project: The UK water network includes pipes of different materials, diameters and ages. These pipes are buried in different soils and have different external factors influencing their resilience. We know that ground movement breaks pipes, but due to the complexity of the environment and pipe network, predicting the number of bursts, and particularly where they are most likely to occur, remains very challenging. Based on the location, height and canopy of the 28 million trees within our study area, you will calculate areas of 'tree influence' on soil moisture, and use these to predict highly local ground movements. It is expected that the incorporation of the new tree datasets into infrastructure-environmental models will enhance our ability to predict the location of burst pipes. Taking a large, historic 10 year, case study in the Anglian Water region, this will be the first time environmental-water infrastructure models based on soil, weather and tree variables will have been developed and tested on this scale.You will test the relationships hypothesised using a range of statistical methods to assess the relative contributions of the infrastructure and environmental variables to each infrastructure failure. The changing impact of trees on local soil moisture under future climates will also be modelled.Due to the age and variable integrity of the UK water network, this work will be of national importance in as it will help to focus the limited resources available for repair and replacement in the areas which will deliver the maximum benefit in reducing leakage and associated energy costs, collateral damage to nearby infrastructure, and minimising the potential impact of failures to both humans and the environment.
