Microwave links potential for runoff prediction: Case study Letnany

Popis výsledku v původním jazyce

Urban storm water management requires rainfall data of high spatial and temporal resolution which is often not available. Path-integrated rain rate information from cellular microwave links (MWL) has a great potential to improve this situation as the MWL network is very dense in urban areas. The paper investigates the MWL potential in terms of urban storm runoff prediction. It compares the rainfall-runoff model performance when using rain rate input from six different rainfall monitoring scenarios derived from stochastically generated rainfall fields: complete rainfall information (reference), rain rates as measured by MWL network and rain rates as measured by four different rain gauge layouts. The paper focuses on effect of rainfall spatial variation description rather than uncertainties in instrumentation itself. Rainfall data (150 rainfall events) for six scenarios were derived from stochastically generated rain fields used as an input to a calibrated rainfall-runoff model. Model performance is evaluated with respect to hydrograph shapes, runoff volumes, peak discharges and time shift of peak discharges. Results show a high potential of the MWL method which in all metrics of interest exhibit a very close similarity with the reference scenario.
