M-K non parametric test and M-K mutation test
4.0
Application background Mann Kendall non parameter test and Mann Kendall mutation test has been widely used in the meteorological and hydrological time series trend analysis, its advantage lies in does not require sample follow certain distribution, and are not subject to the interference of a few outliers hypothesis H0 of original sequences no trend, if 1 alpha / alpha / 2 and Z Key Technology Nothing is difficult, when rainfall events were classified as rr1 and the PI30 values of the rainfall events were higher t

Application background SWAT open source, for the further development of the hydrological model of open source, the source model can be modified to increase the module and reduce the module, and further development, so that the model is more suitable for the study area, can also be re assembled to develop the model, thereby saving costs, improve efficiency, to provide convenient for the development of hydrological model. Key Technology Excluded the influence of antecedent rainfall the, soil loss at the hillslope with ephemeral gully had a significant linear regression equation with PI30. AfterSince; determination coefficient and (R2) Nash-Suttclife efficiency coefficient (ENS) all satisfactory were, results showed that soil loss equations were all run well while soil to applying loss prediction for the three rainfall regimes. the
