New and improved hydraulic radius for channels of the second kind

The Manning’s equation is commonly used to calculate discharge and mean velocity of the uniform flows. According to experimental data, Manning’s equation with constant Manning’s coefficient overestimates the discharge of second-kind channels (channels with a closing top-width), under the partially f...
