Weirs
Coming soon - Darcy Weisbach Equation
Manning's equation is a fundamental tool in hydraulic engineering used to calculate the velocity and flow rate of water in open channels or partially full pipes.
Hydraulic engineering classifies waterfalls into three main types based on channel geometry: circular culverts, rectangular channels, and triangular open channels. Each configuration has distinct characteristics affecting flow behavior and discharge measurement.
Weirs are structures used in open channels to measure and control water flow. The three main types are Cipolletti, rectangular, and V-notch weirs.
