Embodiment Construction
[0065] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0066] The method for estimating slope surface roughness and infiltration parameters under the condition of water scour of the present invention is specifically implemented according to the following steps:
[0067] Step 1 Establish the motion wave equation
[0068] According to the water balance relationship under the condition of water scour, the kinetic wave equation is established, and the equation is:
[0069] ∂ h ∂ t + ∂ q ∂ x = - i - - - ( 1 )
[0070] In formula (1), h is the depth of water flow on the slope / m, t is the water su...
