Embodiment Construction
[0077] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0078] A method for estimating the water transfer rate induced by raindrops and the depth of the mixed layer in the present invention first combines the Philip model and the kinematic wave model to solve the time-varying process of flow at the outlet and slope water depth; then further divide the rainfall process into 3 stages , combined with the solute transport model to solve the runoff solute loss rate, combined with the measured solute loss data to calculate the raindrop-induced water transfer rate e r and mixed layer depth d e .
[0079] Step 1: Combining the kinematic wave model and the Philp infiltration model to establish a slope flow movement model under rainfall conditions;
[0080] Step 2: Build a model of solute migration with runoff.
[0081] Step 3: Combined with the measured data (runoff time, outlet flow, NO in runoff 3 -...
