Impact of changing environment and human activities on urban hydrological and hydrodynamics process – a review

With rapid development of urbanization, flood disaster caused by urbanization is becoming ever more serious, related research is needed increasingly urgently. Combined impact of changing environment and human activities on urban hydrological and hydrodynamic processes is demonstrated here from three aspects: spatial and temporal variability of precipitation, spatial variability of underlying surface and artificial infrastructure. Shortcomings in current research are analyzed, future research prospects are outlined, to provide some reference for urban hydrology and flood disaster management.
