In prior art, the research to overland flow mainly passes through simulating lab test, the simulation of some of which experimental provision
Impact of the slope vegetation to resistance to water-flow is have studied, but general experiment can arrange different gradient tank, and put in bottom of gullet
The plant of upper artificial growth, pasture and water and slotting sticking plaster etc. to simulate slope vegetation, by discharging water or rain making is come mould
Intend slope flow, observe mobility status of the slope flow under different slope vegetations and the gradient, and then analyze slope flow resistance
Change mechanism, although this laboratory facilities can to a certain extent prove that different slope vegetations have influence to insulated stream.
But, artificial vegetation, pasture and water of experimental trough bottom etc. can be with the change vertical bottom of gullets all the time of the gradient, and in reality
Slope vegetation is perpendicular to level rather than domatic.Therefore, the result that existing experimental provision simulation is obtained is inaccurate, is obtained
Achievement in research with actually have certain deviation.But currently without experimental provision to different gradient Caused by Sloping Surfaces vegetation perpendicular to the ground
Such case carries out research simulation, so the impact rule for the modern basin slope vegetation of more true simulation to resistance to water-flow
Rule, needing to be aided with new experimental model carries out the simulated experiment of correlation.
As can be seen here, prior art awaits further improving.
