Abstract: Reliable prediction of hydraulic performance is challenging for Piano Key Weir (PKW) design because discharge capacity depends on three-dimensional geometry and operating conditions. Surrogate models can accelerate hydraulic-structure design, but progress is limited by scarce large, well-documented datasets that jointly capture geometric variation, operating conditions, and functional performance. This study presents WeirNet, a large 3D CFD benchmark dataset for geometric surrogate modeling of PKWs. WeirNet contains 3,794 parametric, feasibility-constrained rectangular and trapezoidal PKW geometries, each scheduled at 19 discharge conditions using a consistent free-surface OpenFOAM workflow, resulting in 71,387 completed simulations that form the benchmark and with complete discharge coefficient labels. The dataset is released as multiple modalities compact parametric descriptors, watertight surface meshes and high-resolution point clouds together with standardized tasks and in-distribution and out-of-distribution splits. Representative surrogate families are benchmarked for discharge coefficient prediction. Tree-based regressors on parametric descriptors achieve the best overall accuracy, while point- and mesh-based models remain competitive and offer parameterization-agnostic inference. All surrogates evaluate in milliseconds per sample, providing orders-of-magnitude speedups over CFD runtimes. Out-of-distribution results identify geometry shift as the dominant failure mode compared to unseen discharge values, and data-efficiency experiments show diminishing returns beyond roughly 60% of the training data. By publicly releasing the dataset together with simulation setups and evaluation pipelines, WeirNet establishes a reproducible framework for data-driven hydraulic modeling and enables faster exploration of PKW designs during the early stages of hydraulic planning.

spent quality snow-eve time with @…'s brilliant & inspiring "other networks," an asynchronous history of non-internet communications. like many readers, i imagine, it made me think of others that might belong & my contribution is... jukeboxes!

#22 on our countdown is the 893 km La Grande River, which drains a modest watershed of 97,600 km2 in Quebec and flows westward into James Bay. In French, La Grande Rivière, and its original Cree name, Chisasibi, both mean "great river") and it is the second-longest river in the province. The river has been extensively developed as a source of hydroelectric power by Hydro-Québec, starting in 1974 a total of 8 hydroelectric dams have been built on the waterway. As a result of the development projects, the Cree people of the region lost parts of their traditional hunting and trapping territories. Organic mercury levels increased in the fish, which forms an important part of their diet, as the organic material is trapped by the rising waters in the new reservoirs.

@… To jest chrzest bojowy przed mieszkaniem za miastem ;) jeszcze 4 lata temu dzwoniłem po hydraulika do wymiany spłuczki, a teraz - elektryk, hydraulik, gazownik, mechanik amator , blacharz - nie ma wyjscia :D
