The use of natural flood management (NFM) measures to address severe flooding received considerable public attention during December 2015-January 2016 storms. Within the Warwickshire-Avon Catchment, UK, high arable and improved grassland land cover with small, isolated communities at risk, lead to the exploration of novel techniques that use farmland high up in flood-prone catchments to hold water and reduce outflow discharge. This paper will discuss the methodology used to identify areas in the Warwickshire-Avon, which could be used to install NFM measures to attenuate the storm peak and provide wider ecosystem services, principally addressing total phosphate and sediment entering the receiving watercourse. This involved constructing a GIS database of catchment geomorphological characteristics whilst simultaneously engaging with those significant stakeholders of farmers and landowners to capture local input and produce a model for applied NFM for future projects looking to explore the role of working with natural processes (WwNP) for flood risk reduction within the agricultural environment. The advantages, disadvantages and key lessons learnt are also presented in this paper, to recognise the benefits and limitations of communities and catchments exploring such methods for flood risk management (FRM).
利用自然洪水管理（NFM）措施来应对严重洪水在 2015 年 12 月至 2016 年 1 月的风暴期间受到了公众的广泛关注。在英国的沃里克郡-埃文流域，高耕地和改良草地的覆盖面积较小，孤立的社区面临风险，这导致人们探索了利用洪水多发流域上游的农田蓄水并减少出流排放的新技术。本文将讨论用于确定沃里克郡-埃文流域内可用于安装 NFM 措施的区域的方法，这些措施可以减轻风暴峰值并提供更广泛的生态系统服务，主要解决进入受纳水道的总磷酸盐和沉积物问题。这涉及构建一个集水区地貌特征的 GIS 数据库，同时与农民和土地所有者等重要利益相关者合作，以获取当地的意见，并为未来的项目创建一个应用 NFM 的模型，这些项目旨在探索在农业环境中利用自然过程（WwNP）来降低洪水风险的作用。本文还介绍了优点、缺点和关键经验教训，以认识到社区和集水区探索此类洪水风险管理（FRM）方法的益处和局限性。
