The analysis of spatial-temporal transition information of land cover vegetation is essential for urban urban flood prevention and urban water resource management.For a further understanding on the mechanism of urban flood.An integration model include runoff and confluence combined with Markov matrix is developed to evaluate the urban inundation influenced by spatial-temporal transfer of land cover vegetation.The model is validated by using historical rainfall and inundation data obtained from investigation and measurement.This analysis are implemented by urban flood models to depict urban flood routing process and submerge locations.Findings of this research reveal that the spatial-temporally of land cover vegetation is the major factor contributing to road inundation in urban area.A comparison for quantifying in spatial-temporal transition of stream flows is also proposed.It is concluded that joint application of hydrological models and Markov theory serve as a good approach for ensemble modelling of inundation and can highlight the spatial-temporal transition in local regions.
