A non-calibrated rainfall-runoff model for large arid catchments, Nahal Zin, Israel

 

Much field based hydrological research has been conducted in arid environments mainly in microscale studies. Two main processes dominate arid zone flood generation:

The present study wants to incorporate this knowledge into a rigorous analysis of a single high magnitude event in a large arid catchment. This required a new appropriate tool, i.e. a rainfall-runoff model not depending on calibration with hydrometric streamflow data.
