A trapezoidal channel carries 5 m³.s⁻¹ of water under uniform flow condition. The channel has a bottom width of 2 m, side slope of 2:1 (horizontal: vertical), and a bed slope of 1%. If the Manning roughness coefficient is 0.03, the conveyance of the channel, in m³.s⁻¹, is

A natural colloidal clay, having the characteristics of absorbing water and swelling 8 to 15 times its dry size, used as an efficient and effective sealing material for farm ponds, is

By depth-area-duration analysis, the maximum average depth of rainfall over a \(10^5\) km² catchment due to a 6-hour storm is 80 mm. For the same storm, the maximum average depth of rainfall for a \(10^4\) km² catchment, in mm, is

A homogeneous earthen embankment has an upstream water level of 12 m. The top width of the embankment is 3 m, and its upstream and downstream slopes (horizontal: vertical) are 2:1 and 2.5:1, respectively. A freeboard of 2 m is provided. The coefficient of permeability of the fill material is 2.5 × 10^-5 m.s^-1. If a 20 m long horizontal filter is placed inward from the downstream toe, the seepage discharge per unit length of the embankment is \(n \times 10^{-5}\) m³.s^-1.m^-1. The value of \(n\) is ______. (Rounded off to two decimal places)

When the bed slope of the discharge carrier in a chute spillway changes from steeper to milder, we provide a
