Webb5 mars 2024 · 5.7: Gradually Varied Flow. Nonuniform flows for which the changes in depth and velocity are so abrupt that radial accelerations distort the vertical distribution of fluid pressure from the hydrostatic condition are called rapidly varied flows. Flow over a sharp-crested dam or weir, and flow under a sluice gate, are good examples. WebbAbstract Based on analytical considerations and supported by experimental information, a general equation has been developed for predicting the flow under a vertical sluice gate in a rectangular channel for free as well as submerged conditions.
