  2. Standard step method - Wikipedia

    en.wikipedia.org/wiki/Standard_Step_Method

    Using Figure 3 and knowledge of the upstream and downstream conditions and the depth values on either side of the gate, a general estimate of the profiles upstream and downstream of the gate can be generated. Upstream, the water surface must rise from a normal depth of 0.97 m to 9.21 m at the gate.

  3. Hydraulic jump - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_jump

    Figure 4: An undular front on a tidal bore. At this point the water is relatively deep and the fractional change in elevation is small. A tidal bore is a hydraulic jump which occurs when the incoming tide forms a wave (or waves) of water that travel up a river or narrow bay against the direction of the current. [16]

  4. Upwind scheme - Wikipedia

    en.wikipedia.org/wiki/Upwind_scheme

    In computational physics, the term advection scheme refers to a class of numerical discretization methods for solving hyperbolic partial differential equations.In the so-called upwind schemes typically, the so-called upstream variables are used to calculate the derivatives in a flow field.

    Parshall flume submerged flow example problem: Using the Parshall flume flow equations and Tables 1-3, determine the flow type (free flow or submerged flow) and discharge for a 36-inch flume with an upstream depth, Ha of 1.5 ft and a downstream depth, H b of 1.4 ft. For reference of locations H a and H b, refer to Figure 1.

  6. Flow net - Wikipedia

    en.wikipedia.org/wiki/Flow_net

    The method consists of filling the flow area with stream and equipotential lines, which are everywhere perpendicular to each other, making a curvilinear grid.Typically there are two surfaces (boundaries) which are at constant values of potential or hydraulic head (upstream and downstream ends), and the other surfaces are no-flow boundaries (i.e., impermeable; for example the bottom of the dam ...

  7. Drop structure - Wikipedia

    en.wikipedia.org/wiki/Drop_structure

    A drop structure, also known as a grade control, sill, or weir, is a manmade structure, typically small and built on minor streams, or as part of a dam's spillway, to pass water to a lower elevation while controlling the energy and velocity of the water as it passes over.
