And it was an effective method in researching the gully erosion generation, development, evolution process and the field gully erosion control through laboratory experiment. Both the erosion amount and the erosion gully topography of the scale model were successfully verified by the measured data of the prototype. The equivalent rainfall process of gully prototype were that the rainfall intensity was 1.25 mm/min and the lasting time was 508 min and precipitation was 636mmn. ![]() Company Tech Stack by G2 Stack Active Products Antetype uses 18 technology products and services including HTML5, jQuery, and Google Analytics, according to G2 Stack. These include Viewport Meta, IPhone / Mobile Compatible, and LetsEncrypt. The experiment results indicated that the extreme rainstorm gully erosion process of the prototype could be reappeared. Antetype is actively using 26 technologies for its website, according to BuiltWith. The model hydraulic boundary from the prototype was the factor of the test process of rainfall. researchh in this area has been of the ex ante type. Second, the normal and scale 10 experiment model was built under complying with the similarities of geometric, rainfall, flow, erosion production sediment transport and bed deformation etc. payy considerable attention to alternative forms of risk management. Their indirect approach is based on an irrelevance. First soil was selected by starting velocity similar. similar to ours, with the buyers ex ante type continuous and ordered by first-order stochastic dominance. The model experiment wan carried out in State Key Laboratory of Soil Erosion and Dry land Farming On the Loess Plateau in Institute of Soil and Water Conservation of Northwest A&F University. The gully prototype is one of Majiagou of Ansai county of Yanan City of Shaanxi Province in China. The similarity of the hydraulic boundary was the necessary and sufficient condition between the model and the prototype. The primary similarity scale relation expressions were the ones of the geometric, rainfall, flow, erosion sediment transport and soil water movement similarity etc. The geometric, kinematical and dynamic similarity must be obeyed for these models. The model and antetype should be in obedience to the same physical equations of rainfall, runoff, erosion, sediment transport, bed deformation and Soil water transport. The basic ideas was that the erosion process of the field erosion gully was forecast by constructing similar model. In view of simulation difficultment of the field gully erosion process because of complex of rainfall runoff erosion mechanism and gully geometry a design means and experimentation technology and its verification test were given based on similarity theory and hydrodynamic principles.
