Combined use of point rain gauges, radar, microwave link and level measurements in urban hydrological modelling

This paper presents the preliminary results of the application of the methodology for the combined use of multiple rainfall and runoff data on a 4800 ha urban catchment within the Emscher river basin in Germany. The time series used come from 12 rain gauges, a C-band and an X-band radar covering the same area and a microwave link. The preliminary results support the methodology's potential as a technique for the combined use of different types of rainfall and runoff data. The results are discussed in terms of applicability, the methodology's limitations and future improvements.
