This study develops a novel reservoir regulation routine, incorporated into a continental-scale hydrologic model in the Nelson, Churchill, Yenisey, Ob, and Lena basins. This regulation routine is integrated into the Hydrological Predictions for the Environment (HYPE) hydrologic model, used for continental-scale applications. Applying this daily timestep regulation routine at 19 reservoirs in the Arctic Ocean watershed, performance is shown to improve upon the reservoir regulation currently available in the HYPE model when testing outflow and storage Nash Sutcliffe Efficiencies (NSEs). Improvements stem from intra-annually variable storage rule curves and a variety of stage-dependent outflow functions, improving simulation skill (median NSE increases of 0.18 over 21 reservoir outflow records and 0.49 over 19 reservoir storage records). This new, reservoir regulation routine is suitable for continental-scale modelling by deriving varying, rather than fixed, threshold water surface levels and associated outflow rules in a programmatic way for multiple reservoirs.

这项研究开发了一种新颖的储层调节程序，并纳入了纳尔逊，丘吉尔，叶尼西，奥布和莱纳盆地的大陆尺度水文模型。该调节程序已集成到用于大陆规模应用的环境水文预测（HYPE）水文模型中。在北冰洋流域的19个水库中应用此日常时步调节例程，在测试流出和存储纳什·苏特克利夫效率（NSE）时，HYPE模型中当前可用的水库调节性能得到改善。改进来自于年内可变的存储规则曲线和各种与阶段有关的流出函数，从而提高了模拟技巧（NSE在21个储层流出记录中平均增加了0.18，在19个储层存储记录中增加了0.49）。这个新的，
