抽象。数据集Future Flows Hydrology是作为“未来流量和地下水位”项目的一部分开发的，旨在提供英格兰，威尔士和苏格兰的瞬时每日河流流量和每月地下水位预测的一致性，以便调查气候变化对全国河流流量和地下水位的作用以及未来可能发生的变化。未来流量水文学源自未来流量气候，这是一个来自哈德利中心的集合预测HadRM 3-PPE的国家集合预测，以适合水文应用的空间和时间分辨率为整个英国提供一套一致的气候变化预测。三个水文模型和一个地下水位模型被用来推导未来流量水文，30个河流站点由两个水文模型模拟，以评估水文模型的不确定性，研究气候变化对水文的影响。未来流量水文包含11个成员的合奏瞬态预测从1951年1月至2098年12月，每个与一个单一的实现从一个不同的变体HadRM 3和一个单一的水文模型。提供了281个河流集水区的每日河流流量和24个钻孔的每月地下水位，作为包含所有11个集合成员的.csv文件。当使用两个水文模型进行单独模拟时，将提供两个单独的.csv文件。由于气候-水文模拟链中的潜在偏差，集水区概况介绍与每个集合相关联。这些包含与水文建模相关的不确定性的信息，当使用观测到的气候和未来流动气候的一个时期的参考时间片1961-1990年所描述的关键水文统计数据的代表。还提供了2050年代部分水文指标的预测变化图。提供了与数据集相关的限制，沿着实际使用建议。Future Flows Hydrology在某些许可条件下可免费用于非商业用途。对于每个研究地点，提供了用于驱动水文模型的日降水量和月潜在蒸散量的集水区平均值，以便进一步探讨气候变化条件下水文模型的不确定性。doi：10.5285/f3723162-4fed-4d9d-92c6-dd17412fa37b
Abstract. The dataset Future Flows Hydrology was developed as part of the project "Future Flows and Groundwater Levels'' to provide a consistent set of transient daily river flow and monthly groundwater level projections across England, Wales and Scotland to enable the investigation of the role of climate variability on river flow and groundwater levels nationally and how this may change in the future. Future Flows Hydrology is derived from Future Flows Climate, a national ensemble projection derived from the Hadley Centre's ensemble projection HadRM3-PPE to provide a consistent set of climate change projections for the whole of Great Britain at both space and time resolutions appropriate for hydrological applications. Three hydrological models and one groundwater level model were used to derive Future Flows Hydrology, with 30 river sites simulated by two hydrological models to enable assessment of hydrological modelling uncertainty in studying the impact of climate change on the hydrology. Future Flows Hydrology contains an 11-member ensemble of transient projections from January 1951 to December 2098, each associated with a single realisation from a different variant of HadRM3 and a single hydrological model. Daily river flows are provided for 281 river catchments and monthly groundwater levels at 24 boreholes as .csv files containing all 11 ensemble members. When separate simulations are done with two hydrological models, two separate .csv files are provided. Because of potential biases in the climate–hydrology modelling chain, catchment fact sheets are associated with each ensemble. These contain information on the uncertainty associated with the hydrological modelling when driven using observed climate and Future Flows Climate for a period representative of the reference time slice 1961–1990 as described by key hydrological statistics. Graphs of projected changes for selected hydrological indicators are also provided for the 2050s time slice. Limitations associated with the dataset are provided, along with practical recommendation of use. Future Flows Hydrology is freely available for non-commercial use under certain licensing conditions. For each study site, catchment averages of daily precipitation and monthly potential evapotranspiration, used to drive the hydrological models, are made available, so that hydrological modelling uncertainty under climate change conditions can be explored further. doi:10.5285/f3723162-4fed-4d9d-92c6-dd17412fa37b
