Broad Crested Weir Calculator

Calculates the flow rate of water passing over a broad-crested weir, which is a type of hydraulic structure used in fluid mechanics. The tool requires users to input physical dimensions, such as the width of the weir crest, the height difference between the upstream and downstream water levels, and sometimes the length of the measuring section. By applying established hydraulic formulas, it determines the discharge (volume flow rate) that crosses the barrier under given conditions. Students studying civil or environmental engineering, as well as physics enthusiasts, use this calculator to model fluid dynamics scenarios. It assists in understanding how changes in water head or weir geometry affect overall water flow. The ability to accurately estimate discharge helps users analyze drainage systems, river management projects, and various open channel hydraulics problems.
