Green infrastructure (GI) river engineering approaches are fundamental to improving the quality, morphology and ecology of our waterbodies; and as part of an overall strategy to help people and communities adapt to the negative effects of climate change. There is also a strong legislative framework which drives the need to protect and enhance the environment.GI solutions include green engineering measures and greening grey river engineering assets with equivalent or increased benefits compared to conventional "grey" infrastructure. They can become self-regenerating and represent a long-term solution that also promotes bio-diversity.There are however, procedural and technical barriers which prevent and obstruct the implementation of green solutions as part of river engineering protection schemes. They are perceived as having a higher risk of failure than grey (or hard) engineering solutions, are insufficiently supported by design and maintenance guidance and procedures or by evidence-based approaches.The objective of the project is to support asset managers, engineers, decision-makers, and other end-users to identify and select green engineering options for river engineering protection in the fluvial environment. The project will develop a decision support framework for selection and application of green infrastructure approaches to fluvial flood defence and erosion risk management interventions in rivers. The proposed work will draw together the existing academic knowledge on green infrastructure measures for flood risk and erosion protection schemes and be complemented with a range of case studies that support their practical application. This will underpin the decision support tool that will be developed. It will answer the questions: what techniques work in different channel typologies and what are their benefits and limitations.The project will pull out the new available and relevant research and experience and knowledge and make it more widely available to practitioners helping them to select green and green-grey solutions using similar type of criteria than when exploring grey solutions. This will help to overcome some of the barriers of prejudice and ignorance and enable the implementation of GI concepts. The uptake of GI approaches will strengthen the functionality of fluvial ecosystems by greening the new and existing river protection and management infrastructure and will assist in compliance with the environmental aspects of the Floods Directive and the Water Framework Directive.

绿色基础设施(GI)河流工程方法是改善我们水体的质量、形态和生态的根本；也是帮助人们和社区适应气候变化负面影响的总体战略的一部分。GI的解决方案包括绿色工程措施和绿化灰色河流工程资产，与传统的“灰色”基础设施相比，其效益相当或更高。它们可以自我再生，是促进生物多样性的长期解决方案。然而，作为河流工程保护计划的一部分，程序和技术障碍阻碍了绿色解决方案的实施。它们被认为具有比灰色(或硬)工程解决方案更高的失败风险，设计和维护指导和程序或基于证据的方法支持不足。该项目的目标是支持资产经理、工程师、决策者和其他最终用户识别和选择绿色工程选项，以保护河流环境中的河流工程。该项目将为选择和应用河流防洪和河流侵蚀风险管理干预措施的绿色基础设施办法制定一个决策支助框架。拟议的工作将汇集关于洪水风险和侵蚀保护计划的绿色基础设施措施的现有学术知识，并辅之以支持其实际应用的一系列案例研究。这将为将要开发的决策支持工具奠定基础。它将回答以下问题：哪些技术在不同的渠道类型中起作用，它们的好处和限制是什么。该项目将带来新的可用和相关的研究、经验和知识，并使其更广泛地可供从业者使用，帮助他们使用与探索灰色解决方案类似的标准来选择绿色和绿色-灰色解决方案。这将有助于克服偏见和无知的一些障碍，并使GI概念得以实施。采用GI方法将通过绿化新的和现有的河流保护和管理基础设施来加强河流生态系统的功能，并将有助于遵守洪水指令和水框架指令的环境方面。
