明渠水理計算(Open Channel Flow Cal)

Features 明渠水理計算(Open Channel Flow Cal)

In the design of irrigation ditches, firstly, based on the conditions of the irrigation area and plant species, the irrigation water flow rate Q is estimated; the design of the drainage ditches is based on the rainfall, catchment area, etc., to estimate the drainage demand flow Q; therefore Generally, the first value obtained when designing a ditch is the flow rate Q, and then according to the size of the construction land, an appropriate channel width B and cross-section type (rectangular or trapezoidal, etc.) are selected, and the water level height d is calculated.
Finally, the designer can add an appropriate water outlet height as the final channel design wall height.
