Tweed Valley Floodplain Risk Management Study - Report

Summary of recommended Floodplain Risk Management options is contained in the report. It considered Existing Flood Risk, Flood Modification Measures, Response Modification Measures, Property Modification Measures, Future Flood Risk, Climate Change, and Planning and Future Development.\r\n\r\nThese measures are summarised in an options assessment matrix which highlights quantifiable impacts, costs and benefits, but also intangible considerations such as social and environmental factors. The matrix can be used to compare options and inform the selection of measures to be adopted for implementation.\r\n\r\nMeasures are also marked on Figure ES-1 in report where possible / appropriate.\r\n\r\nA number of other measures were considered during the study. Measures which were not carried over to this document were found to be not feasible or practicable based on hydraulic assessments and advice from members of the Floodplain Management Technical Sub-committee.

本报告涵盖了推荐的洪泛区风险管理（Floodplain Risk Management）方案概要。本次研究考量了既有洪水风险、洪水调控措施、应急响应调整措施、财产保护调整措施、未来洪水风险、气候变化，以及规划与未来发展方向。

上述措施被汇总至方案评估矩阵中，该矩阵不仅明确了可量化的影响、成本与收益，还纳入了社会、环境等非量化考量因素。该矩阵可用于对比不同方案，为选定拟实施的措施提供决策依据。

在条件允许且适宜的情况下，相关措施已标注于本报告的ES-1附图中。

本次研究期间还考量了多项其他措施。基于水力学评估结果与洪泛区管理技术小组委员会（Floodplain Management Technical Sub-committee）成员的专业建议，未纳入本文档的相关措施被认定为不具备可行性或可操作性。
