Since the major flood event in 2007, RPS has been deeply involved in investigating, understanding and reducing flood risk across the Hull and Haltemprice catchment. RPS has developed and refined a complex integrated catchment model by combining Yorkshire Water's model of below-ground assets with data for the watercourses and overland flow paths obtained from the Environment Agency, East Riding of Yorkshire Council and Hull City Council. RPS used the model to identify major schemes, leading to the design of flood alleviation schemes at Willerby and Derringham, Anlaby and East Ella, and Cottingham and Orchard Park. With further enhancements, the model has been used to better understanding of the complex interactions between the various water systems and solutions are being identified for a long-term plan. Hull has many unique features, driven by its topography, geology and the historical developments of its sewerage network and waterways. These specific challenges require bespoke solutions and there is a clear desire among the partner organisations to work together to drive contemporary blue–green solutions. This requires multi-agency working and progressive thinking to deliver effective flood risk management. This paper reviews the challenges in understanding and resolving these issues.

英格兰赫尔集水区的综合洪水管理

自 2007 年发生重大洪水事件以来，RPS 一直深入参与调查、了解和降低 Hull 和 Haltemprice 集水区的洪水风险。RPS 通过将约克郡水务公司的地下资产模型与从环境署、约克郡东区议会和赫尔市议会获得的水道和陆上流动路径数据相结合，开发并完善了一个复杂的综合集水区模型。RPS 使用该模型来确定主要方案，从而设计了威勒比和德林厄姆、安拉比和东埃拉以及科廷厄姆和果园公园的防洪方案。随着进一步的改进，该模型已被用于更好地理解各种水系统之间的复杂相互作用，并且正在为长期计划确定解决方案。船体有许多独特的特点，受其地形、地质和污水管网和水道历史发展的推动。这些具体挑战需要定制解决方案，合作伙伴组织明确希望共同努力推动当代蓝绿解决方案。这需要多机构的合作和进步的思维来提供有效的洪水风险管理。本文回顾了理解和解决这些问题所面临的挑战。
