Natural Flood Processes for Flood Risk Management

该项目的目的是开发一种新的方法来评估自然洪水管理（NFM）干预措施在集水区水位上的有效性。该方法是基于综合和互补的监测和建模方法，利用北威州的技术，这将导致改进洪水建模软件。将使用来自Shropshire两个集水区的一个新的综合现场监测方案的数据来测试其有效性。该项目有五个目标：了解在新的NFM站点（如Corvedale和Coalbrookdale）的集水区水平上有效的NFM干预措施的规模和位置要求。目标2。通过加强现有的监测计划，制定一项新的技术支持方案，以监测森林保护区内木屑坝的有效性。目标3。通过在EA批准的洪水建模工具中添加河面单元，开发并验证NFM预测方法。这个单元将代表水动力蓄水效应。目标4。将新单元与现场数据集进行对比测试，并与现有洪水模拟软件中目前模拟木屑坝的方法进行对比。目标5。使用新的建模单元来测试木屑坝集群和NFM干预类型的组合，以适应当前和未来的气候变化动态。

The aim of this project is to develop a novel methodology to assess the effectiveness of Natural Flood Management (NFM) interventions at catchment reach levels. The methodology is based on an integrated and complementary monitoring and modelling approach, utilising NRW technologies, which will lead to improved flood modelling software. The effectiveness will be tested using data from a new integrated field monitoring programme at two Shropshire catchments. The project has five objectives:Objective 1. To understand the scale and location requirements for effective NFM interventions at catchment level in new NFM sites (e.g. Corvedale and Coalbrookdale).Objective 2. To develop a novel technology supported protocol for monitoring the effectiveness of woody debris dams at the NFM sites by enhancing the current monitoring programme.Objective 3. To develop and validate a NFM prediction methodology by adding on a unit at reach level to EA approved flood modelling tools. This unit will represent the hydrodynamic impounding effect.Objective 4. To test the new unit against the field site data sets and benchmark against current approaches to modelling woody debris dams in existing flood modelling software.Objective 5. To use the new modelling unit to test clusters of woody debris dams and combinations of NFM intervention types for current and future climate change dynamics.
