A National Scale Model of Green Infrastructure for Water Resources

绿色基础设施能成为水资源计划的一部分吗？我们如何评估新的湿地和森林对哪里的影响最大？这些“自然保水方法”(NWRM)对气候变化的影响有多大？与传统方法相比，这些方法的成本是多少？目前正在根据当地情况回答这些问题，建立了很好的案例研究和试点项目，并理解了它们的产出。在全国范围内，完成的工作要少得多。没有一个模型采用单个西北水资源管理的产出，并形成一个通用的方法，可以用来确定整个英国新的西北水资源管理的一系列选择的成本和收益，并从财务和碳排放的角度绘制解决方案。这项工作建立在牛津研究小组在水资源系统建模规划方面的现有专业知识的基础上，并利用项目合作伙伴的现有知识。我们项目的主要步骤是：1.探索我们项目合作伙伴关于NWRM的知识。我们将在使用西北水资源管理的地点主持讨论，并通过采访专家项目合作伙伴记录这些计划是如何制定的。我们将询问：-建筑成本，开发场地所需的时间，以及运营成本。-他们注意到或监测到的对当地河流的影响我们将把我们得到的答案与世界其他地方的报告中的信息进行比较。利用这些信息，我们将建立一个模型，说明西北偏南地区对水的影响。这将涉及查看每个NWRM上的哪些信息可以告诉我们对水资源的影响将是什么。3.在制作了个别西北水资源模型后，我们将把这一模型应用于我们现有的英国大陆水资源模型。这决定了每个水资源区未来可用的供应和需求，也就是水资源管理单位。4.我们将调查气候变化和人口将如何影响目标3的答案，并考虑其他不确定因素，例如能源和工业对水的需求可能会如何变化，以及如果未来人们减少用水会发生什么。我们将在整个项目期间与我们的合作伙伴合作，就我们的工作编写实用和有用的报告。

Can green infrastructure form part of a water resources plan? How can we evaluate where the most impact from new wetlands and forests can be made? How robust are these 'natural water retention methods' (NWRM) to climate change? How much will they cost in comparison to conventional methods?These questions are currently being answered in a local context, with case studies and pilot projects well established and their outputs understood. At the national scale there has been far less work done. No model has taken the outputs of individual NWRM and formed a generalised approach which can be used to identify the costs and benefits of a range of options for new NWRM across Great Britain and mapped solutions in financial and carbon terms. This work builds on existing expertise on water resource systems modelling planning within the Oxford research group and uses the existing knowledge of project partners.The main steps in our project are:1. Explore the knowledge of our project partners on NWRM. We will host discussions on the sites where NWRM has been used and record the accounts of how these schemes have been developed through interviewing expert project partners. We will ask about: -The cost of building, the time taken to develop the sites, and the operational costs. -The impacts that they noticed or monitored on local riversWe will compare the answers we are given with information from reports from elsewhere in the world.2. Using this information we will make a model of the effects of NWRM on water. This will involve looking at what information on each NWRM can tell us about what the impact on water resources is going to be. 3. Having made a model of individual NWRM, we will apply this to our existing model of water resources for mainland Great Britain. This determines future available supplies and demands for each water resource zone, the management units for water resources. 4. We will investigate how climate change and population will affect the answers from Objective 3, and look at other uncertain factors such as how energy and industry demand for water might change and what happens if people use less water in future.5. We will work with our partners throughout the project to develop practical and useful reports on our work.
