Over the past 50 years changes in UK land-use have been considerable and substantial change is likely to continue. The UK population is projected to increase by 16% to 2035 which will bring about change to the size and structure of urban areas and increased pressure on land management, especially in the south-east. This project, by calling upon a range of tested modelling approaches and associated expertise will advance understanding of the fine-scale impacts of urbanisation on water resources and pollution, which are currently poorly understood. The focus will be on water security in the Thames river basin where projections of future population and climate indicate serious water stress. Detailed case studies at a local scale (including Bracknell and Swindon), where the impacts of past land-use changes on river hydrological and ecological regimes are likely to be large, will be undertaken and a novel integrated modelling approach developed and tested. The approach will then be rationalised and up-scaled for testing across the entire Thames, and, in conjunction with projections of urban development and land management change, used to quantify future effects. These findings will be set in the context of effects indicated to be a direct consequence of climate drivers.

在过去的50年里，英国的土地使用发生了巨大的变化，而且很可能还会继续发生实质性的变化。预计到2035年，英国人口将增加16%，这将给城市地区的规模和结构带来变化，并增加土地管理的压力，特别是在东南部。该项目通过调用一系列经过测试的建模方法和相关的专业知识，将促进对城市化对水资源和污染的细微规模影响的了解，目前对这些影响的了解很少。重点将放在泰晤士河流域的水安全上，那里对未来人口和气候的预测表明，严重的水资源短缺。将在当地(包括Bracknell和Swindon)进行详细的案例研究，过去土地利用的变化对河流水文和生态状况的影响可能很大，并将开发和测试一种新的综合建模方法。然后，该方法将被合理化并扩大规模，以便在整个泰晤士河上进行测试，并与城市发展和土地管理变化的预测一起用于量化未来的影响。这些研究结果将放在气候驱动因素直接影响的背景下得出。
