The Multi-Basin DYnamic Reservoir Simulation Model (MB-DYRESM) has been developed to bridge the gap between the computationally cheap, one-dimensional lake models and the computationally expensive, three-dimensional lake models. It was extended from the classic one-dimensional lake model DYRESM by incorporating a horizontal water exchange algorithm to simulate gravitational mass transport between adjacent sub-basins. Numerical experiments with increasing complexity were carried out for capacity demonstration, in which MB-DYRESM successfully reproduced the thermal structure and mass distribution in each sub-basin with accuracy comparable to and computational speed approximately 300 times faster than the three-dimensional model applied in parallel. In situations where turbulence was suppressed by stratification it actually provided better simulation results. The combination of low computational demand, reasonable spatial resolution of mass flux path and constrained numerical diffusion makes MB-DYRESM a more applicable option for simulations where the balance between affordable computational power and proper spatial resolution is concerned.

多盆地动态水库模拟模型 (MB-DYRESM) 的开发旨在弥合计算成本低的一维湖泊模型与计算成本高的三维湖泊模型之间的差距。它是从经典的一维湖泊模型 DYRESM 扩展而来的，通过结合水平水交换算法来模拟相邻子盆地之间的重力质量传输。进行了越来越复杂的数值实验进行容量论证，其中MB-DYRESM成功地再现了每个子盆地的热结构和质量分布，其精度与并行应用的三维模型相当，计算速度大约快300倍. 在通过分层抑制湍流的情况下，它实际上提供了更好的模拟结果。低计算需求、质量通量路径的合理空间分辨率和受约束的数值扩散相结合，使 MB-DYRESM 成为更适用的模拟选项，其中涉及负担得起的计算能力和适当的空间分辨率之间的平衡。
