Abstract

Theoretical assumptions and practical approaches to temporal and spatial distribution of rainfall intensity in urban watersheds is still a research topic. The speed and direction of movement of rainfall events above urban watersheds are principal hydrologic parameters, which influence a rainfall-runoff process. This contribution reviews three methods, namely the Inverse Distance-Weighted Method (IDWM), Time Shift Method (TSM) and newly developed Geometrical Method (GM). The principal assumption of all three methods is based on the calculation of fictitious rainfall intensity at a particular location as weighted interpolation among the nearest real rain gauge stations. Any rainfall event above the urban watershed can be classified either as moving or non-moving storm. While the Inverse Distance-Weighted Method can be used for non-moving storms, the other two methods can describe the parameters of moving storms. Model RainGen, which was originally developed to create a basic source of rainfall data for rainfall-runoff mathematical models in urban watersheds, may be used not only for visualization but as well as for comparing of the measured and computed results. Case study for moving storms in Prague shows the results of TSM and GM methods.
