Towards controlling urban storm water runoff with rainfall information from telecommunication microwave links

Popis výsledku v původním jazyce

The ability to predict rainfall-runoff response of an urban catchment is crucial for managing effectively drainage systems and thus control discharges from urban areas. In this paper we investigate potential of commercial microwave links (MWL) to capturethe spatio-temporal rainfall dynamics and thus improve rainfall-runoff modelling in urban areas. Specifically, we perform numerical experiments with virtual rainfall fields and compare the results of MWL rainfall reconstructions to those of rain gauge (RG) observations. For a case study of a small sewer system, we are able to show that MWL networks in urban areas are sufficiently dense to provide good information on spatio-temporal rainfall variability and can thus considerably improve pipe flow prediction and enable better control of discharges from urban areas. This is especially beneficial for high-intensity rainfalls, which usually have a high spatial variability that cannot be accurately captured by RG point measurements.
