As flood hazard, and the frequency of extreme floods in particular, is projected to increase in the future the risks associated with the impact of wood in rivers is also likely set to increase. Thus, in order effectively manage wood in river systems there is a need to understand and predict how the presence of wood will produce ecological benefits and how these benefits trade-off against the risks associated with its presence. This is not currently possible and this project seeks to address this significant knowledge gap. In order to improve understanding of this benefit-risk relationship there is a need to overcome major deficiencies in knowledge, including: (i) a lack of any attempt to systematically quantify the driving variables in wood dynamics and despite the rapid development and evolution of high-resolution measuring technologies there are inconsistencies in the type and methods of data collected. This means that there is limited capacity to validate predictive models of risk; (ii) research has been undertaken in an ad hoc manner and so many of the empirical relationships of the cost-benefits of wood dynamics have been drawn from case studies. Since the empirical relationships are used to underpin management strategies it is unclear of the global applicability of these sites beyond specific environments in which the relationships were derived, and (iii) limited understanding of how predicted increases in the frequency and intensity of flood events will serve to increase the risks posed by wood in river systems. By bringing the diverse skill set of the project partners together for the first time means that this network is now in a position to address these deficiencies. This proposal draws on the experience and expertise of all project partners who work across different global catchments representative of different hydroclimates and operationalise different management strategies. By doing this the network will deliver a globally derived and globally applicable standardised approach to both quantifying the impact of, and predicating current and future risks posed by, wood in rivers. The project will outcome 6 deliverables, including: D1 - A fully searchable interactive global digital risk atlas; D2 - A new series of directly comparable, standardised metrics and measuring protocols for quantifying, modelling and managing wood dynamics in rivers; D3 - A systems dynamics model which can be used to predict how key management interventions and environmental change scenarios affect risk associated with wood in rivers; D4 - A series of journal papers (included already outline agreed Nature Reviews article) to disseminate research findings to the academic and practitioner community; D5 - A series of funding proposals to underpin future sustainability of the network; and D6 - A series of events to further expand the scope of the network to the academic and practitioner communities.

随着洪水危害，尤其是极端洪水的频率，预计将来会增加与木材在河流中的影响有关的风险也可能会增加。因此，为了有效地管理河流系统中的木材，有必要理解和预测木材的存在将如何产生生态益处，以及这些利益如何权衡与其存在相关的风险。目前这是不可能的，该项目旨在解决这一重要的知识差距。 为了提高对这种利益风险关系的了解，需要克服主要缺陷知识，包括：（i）缺乏系统地量化木材动力学中的驾​​驶变量的任何尝试，尽管高分辨率测量技术的快速发展和进化，但收集到的数据类型和方法中仍然存在不一致的方法。这意味着验证风险预测模型的能力有限； （ii）研究是以临时的方式进行的，从案例研究中得出了木材动力学成本效益的许多经验关系。由于经验关系用于支持管理策略，因此不清楚这些站点的全球适用性超出了这种关系的特定环境，并且（iii）（iii）对洪水事件频率和强度的预测如何增加的理解将有助于增加木材系统中木材所带来的风险。通过将项目合作伙伴的多样化技能汇集在一起​​，这意味着该网络现在可以解决这些缺陷。 该建议借鉴了所有项目合作伙伴的经验和专业知识，这些项目合作伙伴在代表不同氢化物的不同全球流域工作并运行不同的管理策略。通过这样做，网络将提供全球且全球适用的标准化方法，以量化木材在河流中造成的当前和未来风险的影响。 该项目将成果6个可交付成果，包括：D1-完全可搜索的交互式全球数字风险地图集； D2-一系列直接比较的，标准化的指标和测量协议，用于量化河流中的木材动力学； D3-一种系统动力学模型，可用于预测关键管理干预措施和环境变化方案如何影响河流中木材相关的风险； D4-一系列的期刊论文（包括已经概述的大自然评论文章），向学术和从业者社区传播研究结果； D5-一系列资金提案，以支持网络未来的可持续性；和D6-​​一系列事件，以进一步将网络范围扩大到学术和从业者社区。
